An Introduction to Brown Dwarfs by John Gizis, 2024

From very-low-mass stars to super-Jupiters

This book provides an introduction to brown dwarfs aimed at advanced undergraduates and beginning graduate students, supplementing stellar astrophysics or (exo)planetary science classes. It emphasizes the key theoretical ideas and the main observational results that support those ideas.

The first chapter is an introduction to the concept of brown dwarfs, their similarities and differences with stars and planets, and classification challenges. The second section examines brown dwarf atmospheres, with an emphasis on both understanding the key concepts and making use of the detailed models. The final major section addresses the formation of brown dwarfs, the initial mass function, and the related problem of brown dwarf multiplicity.

Key features

• First book aimed at brown dwarfs.

• An extension of stellar astrophysics and exoplanetary astronomy.

• Includes Python programs.

• Includes problems and solutions.

An article published in "The Astrophysical Journal" reports the identification of 64 brown dwarf candidates in the star cluster NGC 602 in the Small Magellanic Cloud, one of the Milky Way's satellite galaxies. A team of researchers used the James Webb Space Telescope to obtain the sensitivity and resolution needed to detect possible objects halfway between the planet and the star about 200,000 light-years away.

Two articles, one published in the journal "Nature" and one in "The Astrophysical Journal Letters", report the results of two independent studies on Gliese 229 B, the first brown dwarf whose existence was confirmed, which conclude that it's actually a pair of close brown dwarfs.

I suspect that just as there are many stellar doubles out there, so it goes with brown dwarfs

Stellar surprise – astronomers uncover methane emission on a cold brown dwarf for the first time
