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.
