The Stellar Winds Atlas II: Black Hole Formation at Solar Metallicity
Amedeo Romagnolo, Floor S. Broekgaarden, Alex C. Gormaz-Matamala +7
Stellar winds are a primary source of uncertainty in predicting the masses of black holes (BHs) from massive stars. At solar metallicity, theoretical models lead to widely divergen…
How Common Are Common Envelopes? Quantifying Their Role in Forming Gravitational-Wave Sources
Floor S. Broekgaarden, Ana Lam, Sasha Levina +14
A central goal of gravitational-wave astronomy is to use merging binary black hole (BBH), black hole-neutron star (BHNS), and binary neutron star (BNS) systems as fossils to recons…
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…
