    Abstract:
    Extremely compact objects (R<3 GM/c2) contain null
    geodesics that are captured by the object. Certain part of neutrinos
    produced in their interior will therefore be trapped, thus influencing
    neutrino luminosity of the objects and their thermal evolution. This
    effect was investigated for the interior Schwarzschild spacetimes with
    the uniform distribution of energy density by Stuchlík, Z.,
    Török, G., Hledík, S. and Urbanec, M. (2005), Neutrino
    trapping in extremely compact objects, Classical Quantum Gravity,
    submitted. We will investigate here influence of the cosmological
    constant on the trapping phenomena. We use again the simplest model for
    interior of such objects based on the interior Schwarzschild-(anti-)de
    Sitter spacetimes. We determine behaviour of the trapping coefficients,
    i.e., „global“ one representing influence on the neutrino luminosity
    and „local“ one representing influence on the cooling process.
