I am beginning to try to understand the gravothermal catastrophegravothermal catastrophe. I was hoping someone could provide an explanation to help me understand what the gravothermal catastrophe is and why it is important, as well as physical systems where it is important.
Unfortunately, there is no Wikipedia article on the subject. I am hoping for an explanation that is maybe a little more technical than a Wikipedia explanation but still easy for someone unfamiliar with the subject to understand.
