Trapping of neutrinos in extremely compact stars
Abstract
Extremely compact objects (9GM/4c^2<R<3GM/c^2) contain trapped null geodesics that cannot escape the objects. Certain part of neutrinos produced in their interior will therefore be trapped, thus influencing neutrino luminosity of the objects and consequently their thermal evolution. The existence of trapped neutrinos also indicates possibility of ``two-temperature'' cooling regime of extremely compact objects. It is shown that the trapping of neutrinos can be relevant even for moderately extremely compact stars.
