    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.
