An Introduction to Stellar Astrophysics Review

Average Reviews:

(More customer reviews)This is one of the best book on the market that covers the most important topics of stellar astrophysics (stellar formation, stellar atmospheres, stellar interiors, stellar evolution, etc.) at the advanced undergraduate level. The sections on the Saha equation, the radiative transfer equation, stellar atmospheres and on nucleosynthesis are excellent. The explanations of the physical phenomena are clear and direct which makes this an excellent textbook.

An Introduction to Stellar Astrophysics aspires to provide the reader with an intermediate knowledge on stars whilst focusing mostly on the explanation of the functioning of stars by using basic physical concepts and observational results.
The book is divided into seven chapters, featuring both core and optional content:
Basic concepts
Stellar Formation
Radiative Transfer in Stars
Stellar Atmospheres
Stellar Interiors
Nucleosynthesis and Stellar Evolution and
Chemically Peculiar Stars and Diffusion.

Student-friendly features include:
Detailed examples to help the reader better grasp the most important concepts
A list of exercises is given at the end of each chapter and answers to a selection of these are presented.
Brief recalls of the most important physical concepts needed to properly understand stars.
A summary for each chapter
Optional and advanced sections are included which may be skipped without interfering with the flow of the core content.

This book is designed to cover the most important aspects of stellar astrophysics inside a one semester (or half-year) course and as such is relevant for advanced undergraduate students following a first course on stellar astrophysics, in physics or astronomy programs. It will also serve as a basic reference for a full-year course as well as for researchers working in related fields.

Modeling and Control of Antennas and Telescopes (Mechanical Engineering Series) Review

Average Reviews:

(More customer reviews)This book fills an interesting niche in the field. Large antennas and large telescope structures are very similar, and the fundamental approaches used to understand their performance are the same. The author does a commendable job of presenting the necessary information in a clear and understandable way; let down slightly by a few typos and some slightly weak error checking and editing (this book is not cheap - this sort of thing should be picked up in the proofing) - but despite this it is well worth the money.
I work for a large telescope project and this book is worth purchasing simply to get the perspective of an experienced practitioner in the field, and to see common questions ('Is a velocity loop really necessary?') comprehensively yet compactly addressed. Overall, an interesting and worthwhile book - would that more engineers in the field could - and would - produce something similar. The discipline would be the richer for it.

The book shows, step by step, the design, implementation, and testing of the antenna/telescope control system, from the design stage (analytical model) to fine tuning of the RF beam pointing (monopulse and conscan). The purpose of this book is to present the implementation of the new theoretical developments in structural dynamics and control theory in the antenna and telescope industry. Also to present the significant improvement in pointing accuracy of the antenna and telescope when the presented techniques are implemented.This book fills the need in the antenna/telescope control techniques. For long time, since 1990 when the last book was published, there was no publication on the antenna/telescope/radar modeling and control.
