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…
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…
Counting States: A Combinatorial Analysis of SQM Fragmentation
A. Bernardo, L. Paulucci, L. M. de Sá +1
The Strange Quark matter (SQM) hypothesis states that at extreme pressure and density conditions a new ground state of matter would arise, in which half of the \textit{down} quarks…
Effects of a non-universal IMF and binary parameter correlations on compact binary mergers
L. M. de Sá, A. Bernardo, R. R. A. Bachega +2
Binary population synthesis provides a direct way of studying the effects of different choices of binary evolution models and initial parameter distributions on present-day binary…
