Stellar black holes and neutron stars, so-called compact objects, are the final stages in the evolution of massive stars with more than ~8 solar masses. If the mass of a compact object is greater than the theoretical mass ...
Since the discovery of their photovoltaic capabilities, hybrid metal organic halide perovskites have continued to set new record efficiencies. Perovskite-based solar cells promise the possibility to be fabricated in more ...
Black holes and neutron stars are compact remnants of massive stars at the endpoint of stellar evolution. As they have consumed all their nuclear fuel they are not radiating themselves anymore, which makes isolated compact ...
Neutron stars are compact objects, characterized by R~10-14 km radius, M~1.4Msun and extremely high central densities ~10e15 g/cm^3. If they are part of a binary system, a flow of matter can take place from the companion ...
