Abstract

The plan aims identify the presence of exotic mater in stellar interiors. For this we must execute the necessary calculations to interpret the binding energy emitted in neutrinos (by SN1987A and other events) and analyze its viability in terms of the collapse theories with and without hadron-quark phase transitions, in addition to study the relation of the evolutionary histories of the black widow systems in relation to its internal structure to identify them as candidates to contain quark matter, in the face of crescent evidence of mass greater than well-accepted 1.97±0.03 M_™published for Demorest et al. in 2010.
