Astronomer, Cartographer and Naturalist of the New World Volume 1: Life, Work and Legacy
This volume, Volume 1, presents Marggrafe’s stunning biography. Volume 2 consists of a text edition of his astronomical legacy, prepared for the printing press in the 1650s, but only now finalized and published. Georg Marggrafe (1610-1643) is today hailed as the principal author of an influential account of the natural history of Northern Brazil and as compiler of the first accurate map of the area, which is considered as one of the most elegant products of seventeenth-century Dutch cartography. But initial he had the ambition to become known in astronomy. With the support Johan Maurits van Nassau-Siegen, then governor-general of colonial Dutch Brazil, he built in Recife the first European-style astronomical observatory on the South-American continent, where he systematically charted the southern stars. He intended to supplement the famous astronomer Tycho Brahe, who charted the Northern sky half a century before. But Marggrafe’s untimely death (and the negligence of a Leiden professor) prevented the publication of his valuable observations. As a result, Marggrafe did not achieve fame in astronomy, but instead became famous for his equally remarkable other achievements.

STUDIES IN NUCLEAR SCATTERING USING MANNING-ROSEN POTENTIAL
The first explanation on the properties of the nuclear force came from Yukawa. It said that interaction between two nucleons is mediated by mesons (heavy bosons). The most effective practical model for a quantitative nucleon-nucleon potential has been meson-exchange theory ever since. Manning-Rosen potential (M-R pot) is a diatomic molecular potential but in the moderate range it behaves as the Yukawa potential. Thus M-R pot can be considerable for the nuclear domain also. We have treated both the on- and off-shell two-particle nuclear scattering in the non-relativistic region.

The elliptical restricted three body problem
Restricted three body problem is used to study the behavior of spacecraft, asteroids, and moons in systems like the Earth-Moon-Sun, Jupiter's moons etc. The present book deals with the problem of finding the existence and stability of the equilibrium points in the Elliptical restricted 3-body problem. It also helps in analyzing Lagrange points, which are positions in the orbital plane of the two massive bodies where the third body can maintain a stable position. Resonances play a critical role in understanding the long-term evolution of orbits in celestial mechanics. The linear and non-linear stability has been studied for 3rd and 4th order resonance.

Growth and characterizations for CRXW1-XSE2 single crystals
Transition metal dichalcogenide is a family of thin semiconducting materials in the form of MX2 in which M represents the transition metals molybdenum (Mo), tungsten (W), vanadium (V), etc. and X represents chalcogen atoms sulphur (S), selenium (Se), tellurium (Te). The transition metal layer is sandwiched between layers of chalcogen atoms. By virtue of excellent electrical and chemical properties, high mobility of charge carriers, low-power consumption, high flexibility and stretchability, lightweight, good mechanical robustness, and environmental stability, these materials proved themselves appropriate for flexible gas sensing applications.

Host Stars and their Effects on Exoplanet Atmospheres
This comprehensive introductory overview describes the emission of radiation (X-rays to radio) and the winds of host stars and how they control the past, present, and future evolution of an exoplanet. The book focuses on topics that are critically important for understanding exoplanet atmospheres but are often posed without a comprehensive and detailed understanding of the host star and its effects on the exoplanet. Although both stars and exoplanets are usually studied in isolation, in this book they are treated as an integrated system. Whether or not an exoplanet can retain its atmosphere and the chemical composition of the atmosphere depends critically on the strength, time dependence, and spectral energy distribution of the host star's radiation, flares, coronal mass ejections, and wind, which are described in detail in the book. The book describes the roles played by magnetic fields in the coronae and chromospheres of host stars that tie together stellar active phenomena with major effects on exoplanet atmospheres. In the era of JWST and very sensitive ground- and space-based instruments, a critical topic is the noise imposed on radial velocity measurements and transit photometry and spectroscopy by the host star's activity and variability that fundamentally limit our understanding of exoplanet properties. This topic is addressed in detail in the book. This book is written primarily for graduate students and researchers who are studying exoplanet atmospheres and habitability, but who may not have a background in the physics and phenomenology of host stars. The book could serve as a reference book for graduate level classes on exoplanets. Nonspecialists with a scientific background should also find this text a valuable resource for understanding the critical issues of contemporary exoplanet research. This new edition of "Host Stars and their Effects on Exoplanet Atmospheres" is a major revision of the existing book in the following ways:It includes a new discussion of how stellar noise fundamentally limits our understanding of exoplanet atmospheresIt demonstrates in detail how stellar activity acts as fundamental driver of exoplanet atmosphere evolutionIt provides an outlook on how the field of exoplanet atmospheres and bio-astrophysics is being driven by powerful new telescopes and instrumentsIt extensively updates many chapters, in particular concerning host star extreme- and far-ultraviolet emission, stellar winds, stellar surface structures, the effects of space weather on exoplanets, and provides a realistic evaluation of habitability taking into account the evolution of host star activity.

Mars and the Earthlings: A Realistic View on Mars Exploration and Settlement
In an era of public Mars fascination, this book offers an objective presentation of the challenges of crewed Mars missions and discusses scenarios of Mars settlements under scientific, technical, social, economic , ethical and political aspects. With the aim to make the reader comprehend what is plausible and what is at stake, the book tries to clarify misconceptions and half-truths spreading rapidly in the public. The authors argue that approximations and misinformation should be countered for two main reasons. First, to avoid missing out on the benefits that Mars exploration may bring, including major scientific discoveries and an inspiring, federative human endeavor. Second, to remediate dangerous delusions - such as the idea that humanity could be transferred there should the Earth become inhabitable in the near term. In preparation for this book a group of European, world-renowned scientists from fields as diverse as astronomy, planetology, geology, biology, philosophy, or economics, as well as astronauts and science-fiction writers, was gathered to discuss Mars missions ranging from near-term robotic missions, all the way to large-scale settlements and even the feasibility of terraforming. For each, they draw arguments from their domains of expertise to discuss what is feasible and what is desirable. The result provides researchers with an objective review of the field, policy makers with a reference to make informed decisions, and the general public with a tool to form educated opinions.

Unified Energy Dynamics
Unified Energy Dynamics (UED) is a groundbreaking exploration into the essence of energy, offering a revolutionary framework that bridges the realms of quantum mechanics, cosmology, and philosophy. Authored by Sandeep Chavan, this book redefines energy as the cornerstone of all existence, presenting a cohesive narrative that integrates science, metaphysics, and practical applications.At the heart of UED is the concept of energy existing in dual states: stable energy, a timeless reservoir of latent potential, and active energy, the dynamic force driving transformation. This duality forms the basis of all cosmic phenomena, from quantum interactions to galactic evolution. Chavan introduces the infinite energy pool as the unifying medium that sustains existence, providing the foundation for matter, consciousness, and the interplay between stability and dynamism.One of the book's most innovative contributions is the replacement of the Big Bang with the concept of the First Disturbance-a continual quantum superposition event that initiated the interaction between stable and active energy. This perspective shifts the focus from a singular creation event to an ongoing dynamic process, connecting the emergence of matter, photons, and consciousness.The book also delves into exotic states of matter, such as Bose-Einstein Condensates (BECs) and Fermionic Condensates, as tangible examples of UED principles. These states, formed at near-absolute zero temperatures, demonstrate the transition from chaotic energy to quantum coherence, providing insights into universal stability and the early universe's conditions.Practical applications of UED are woven throughout, highlighting its relevance to quantum computing, superfluidity, and sustainable technologies. The framework extends beyond traditional physics, offering a unified perspective on phenomena like entropy, time, and consciousness. Chavan emphasizes energy's role in bridging the tangible and intangible, redefining our understanding of existence.With its innovative concepts, practical implications, and philosophical depth, Unified Energy Dynamics (UED) by Sandeep Chavan offers a transformative vision of the universe, inspiring readers to rethink the nature of energy, matter, and the interconnectedness of all things. This book is a must-read for scientists, philosophers, and anyone seeking a deeper understanding of reality.

THE TRUTH OF THE ORIGIN OF THE UNIVERSE (A NOVEL PERCEPTION OF THE BIG BANG AND THE UFO'S)
The Big Bang and UFOs: Unworthy Credit!The topic of undeserving credit given to the Big Bang and UFOs is a controversial one, with many people having strong opinions on the matter. While both the Big Bang theory and the existence of UFOs have been widely accepted, the author argues that they are given too much credit and recognition without sücient evidence to support their claims.The Big Bang theory is widely accepted as the most plausible explanation for the origin of the universe. Some critics argue that it is not the only possible explanation for the universe's origins. Some alternative theories, such as the steady-state theory or the oscillating universe theory, have been proposed as alternatives to the Big Bang theory.Similarly, the existence of UFOs is a topic that has been hotly debated for decades. While there have been countless reports of UFO sightings and encounters, there is a lack of concrete evidence to support the existence of extraterrestrial visitors. While the Big Bang theory and UFOs may be popular topics in popular culture, it is important to approach them with a critical eye and to consider the evidence before giving them undeserving credit.
