Gravitational instability of polytropic spheres containing region of trapped null geodesics: a possible explanation of central supermassive black holes in galactic halos
Zdeněk Stuchlík, Jan Schee, Bobir Toshmatov +2
We study behaviour of gravitational waves in the recently introduced general relativistic polytropic spheres containing a region of trapped null geodesics extended around radius of…

Polytropic spheres containing regions of trapped null geodesics
Jan Novotný, Jan Hladík, Zdeněk Stuchlík
We demonstrate that in the framework of standard general relativity polytropic spheres with properly fixed polytropic index and relativistic parameter , giving ratio of the…
