The Galactic Black Hole mass distribution

L S. Rocha, N. Pires, L. M. de Sá +8

The population of extragalactic black holes has been significantly expanded and better understood since the first detection of gravitational waves. Over the past decade, approximat…

The mass of the neutron star in 4U 1820-30 revisited

Marcio G B de Avellar, Jorge E Horvath, Nathalia D Pires +7

We revisit the mass of the neutron star in the ultracompact binary 4U 1820--30 in light of a recently reported transient absorption feature at about 3.8 keV, interpreted as a gravi…

Evolution of long-period compact radio sources driven by winds

J. E. Horvath, Lucas M. de Sá, Lívia S. Rocha +3

We address in this work the nature and evolution of the long-period compact star sources, which has recently added several unexpected members. The central hypothesis is that partic…

Mass Distribution and Maximum Mass of Neutron Stars: Effects of Orbital Inclination Angle

Lívia S. Rocha, Jorge E. Horvath, Lucas M. de Sá +3

Matter at ultra-high densities finds a physical realization inside neutron stars. One key property is their maximum mass, which has far-reaching implications for astrophysics and t…

A light strange star in the remnant HESS J1731-347: minimal consistency checks

J. E. Horvath, L. S. Rocha, L. M. de Sá +5

Context: Recently, Doroshenko and collaborators reported a very low-mass compact star, a Central Compact Object named XMMU J173203.3-344518 inside the supernova remnant HESS J1731-…

An Overview of Compact Star Populations and Some of Its Open Problems

L. M. de Sá, A. Bernardo, R. R. A. Bachega +3

The study of compact object populations has come a long way since the determination of the mass of the Hulse-Taylor pulsar, and we now count on more than 150 known Galactic neutron…
