Gravitational instability of polytropic spheres and generalized thermodynamics
P. H. Chavanis
We complete the existing literature on the structure and stability of polytropic gas spheres reported in the classical monograph of Chandrasekhar (1942). For isolated polytropes wi…

Gravitational instability of finite isothermal spheres in general relativity. Analogy with neutron stars
Pierre-Henri Chavanis
We investigate the effects of relativity on the gravitational instability of finite isothermal gaseous spheres. In the first part of the paper, we treat the gravitational field wit…

Gravitational instability of finite isothermal spheres
P. -H. Chavanis
We investigate the stability of bounded self-gravitating systems in the canonical ensemble by using a thermodynamical approach. Our study extends the earlier work of Padmanabhan [A…
