Edited by Sara Seager

Sara SeagerFor the first time in human history, we know for certain the existence of planets around other stars. Now the fastest-growing field in space science, the time is right for this fundamental source book on the topic which will lay the foundation for its continued growth. Exoplanets serves as both an introduction for the non-specialist and a foundation for the techniques and equations used in exoplanet observation by those dedicated to the field.

Exoplanet Atmospheres: Physical Processes

By Sara SeagerSara Seager

Over the past twenty years, astronomers have identified hundreds of extrasolar planets--planets orbiting stars other than the sun. Recent research in this burgeoning field has made it possible to observe and measure the atmospheres of these exoplanets. This is the first textbook to describe the basic physical processes--including radiative transfer, molecular absorption, and chemical processes--common to all planetary atmospheres, as well as the transit, eclipse, and thermal phase variation observations that are unique to exoplanets.

In each chapter, Professor Sara Seager offers a conceptual introduction, examples that combine the relevant physics equations with real data, and exercises. Topics range from foundational knowledge, such as the origin of atmospheric composition and planetary spectra, to more advanced concepts, such as solutions to the radiative transfer equation, polarization, and molecular and condensate opacities. Since planets vary widely in their atmospheric properties, Seager emphasizes the major physical processes that govern all planetary atmospheres.

Moving from first principles to cutting-edge research, Exoplanet Atmospheres is an ideal resource for students and researchers in astronomy and earth sciences, one that will help prepare them for the next generation of planetary science.

The first textbook to describe exoplanet atmospheres Illustrates concepts using examples grounded in real data Provides a step-by-step guide to understanding the structure and emergent spectrum of a planetary atmosphere Includes exercises for students.


"Exoplanet Atmospheres is a major scholarly contribution to an exciting, scientifically important, and rapidly expanding area of research in astrophysics, written by one of its intellectural leaders. Seager pulls together a comprehensive and meticulously organized set of scientific results and techniques. This book will be a bible for students and professionals interested in exoplanet atmospheres."

Exoplanets and the Search For Habitable Worlds

By Sara Seager

Have you ever wondered whether life exists beyond Earth?
Are you curious to know how many planets just like Earth might be out there?
To answer these and other common questions Professor Seager has written the factual non-fiction book: Is there Life Out There? The Search for Habitable Exoplanets. Exoplanets are planets orbiting stars other than the sun. By searching for exoplanets like Earth, science will one day answer humanity's oldest question: Is There Life Out There? Few understand that science fiction is becoming science fact with a serious search for planets beyond Earth that can support life.


"Brilliant, engaging, comprehensive, and visually attractive. It's sure to be a hit."
- Dr. Alan Stern, former NASA SMD Associate Administrator
