Abstract
Abstract Bremsstrahlung photons emitted during nucleon-nucleus reactions in compact star are investigated.
Influence of density of stellar medium on intensity of emission is studied at first time in quantum approach.
Bremsstrahlung model is generalized, where new term describing influence of stellar medium is added to interactions between nucleons of nucleus (in frameworks of nuclear model of deformed oscillatoric shells).
Polytropic EOS, Chandrasekar EOS and Harrison-Wheeler EOS are applied for calculations.
Unified EOS of neutron-star matter of Haensel and Potekhin based on FPS an SLy EOSs is used for tests.
Bremsstrahlung calculations are tested on existed measurements of bremsstrahlung in the scattering of protons off the \isotope[197]{Au} nuclei at energy of proton beam of $E_{\rm p}=190$~MeV.
Many properties of bremsstrahlung emitted from nuclear processes in stellar medium of compact stars are studied at first time.
In particular, the spectra of photons in the scattering of protons and neutrons off \isotope[4]{He}, \isotope[8]{Be}, \isotope[12]{C}, \isotope[16]{O}, \isotope[24]{Mg}, \isotope[40]{Ca}, \isotope[56]{Fe} are estimated in dependence on density of stellar medium.
Medium of white dwarfs has small influence on the bremsstrahlung emission from nuclear processes, while
bremsstrahlung emission is intensive in neutron stars and it is changed essentially in dependence on stellar density and structure.
