Best practices in software citation

Phil R. Van-Lane, Floor S. Broekgaarden, Daniel S. Katz +11

Software is both a foundational tool and a primary output of modern computational research, yet citation practices for software remain inconsistent, incomplete, and rarely machine-…

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…

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…
