Kilonova/Macronova Emission from Compact Binary Mergers
Published 2016-01-01“…We review current understanding of kilonova/macronova emission from compact binary mergers (mergers of two neutron stars or a neutron star and a black hole). Kilonova/macronova is emission powered by radioactive decays of r-process nuclei and it is one of the most promising electromagnetic counterparts of gravitational wave sources. …”

Pulse-profile Modeling and Spin–Orbit Alignment in a Suzaku Sample of Accreting X-Ray Binary Pulsars
Published 2024-01-01“…The implications of our study are as follows: (a) apparently, accretion torques have had time to erase spin–orbit misalignment caused by supernova kicks in two-thirds of the systems; (b) many X-ray binary pulsars have dominant dipolar surface magnetic fields, in contrast to the recently reported exotic configurations in millisecond pulsars; and (c) if the binary inclinations can be determined by pulse-profile modeling, even for a subset of the ∼200 known X-ray binary pulsars, most of which orbital inclinations are as yet poorly constrained, it raises the prospect of tightening dramatically ongoing neutron-star mass determinations. This is because masses in binary systems overwhelmingly come from an orbital-mechanics formulation (Kepler’s third law), in which the dominant source of uncertainty is the inclination of the orbital plane.…”

Stability of compact stars in a uniform density background cloud
Published 2024-12-01“…Abstract We are discussing a scenario where a compact star (neutron star, NS) is embedded in a thin, uniform density background cloud (a remnant cloud after a supernova or a cloud generated from the late stages of a star e.g., a planetary nebula or asymptotic red giant phases) and its effect on the stability of the compact star. …”

Population of Merging Compact Binaries Inferred Using Gravitational Waves through GWTC-3
Published 2023-03-01“…The Gravitational-Wave Transient Catalog 3 (GWTC-3) contains signals consistent with three classes of binary mergers: binary black hole, binary neutron star, and neutron star–black hole mergers. We infer the binary neutron star merger rate to be between 10 and 1700 Gpc^{−3} yr^{−1} and the neutron star–black hole merger rate to be between 7.8 and 140 Gpc^{−3} yr^{−1}, assuming a constant rate density in the comoving frame and taking the union of 90% credible intervals for methods used in this work. …”

Revisiting the 3α reaction rates in helium burning stars
Published 2025-01-01“…Helium burning is one of the most fundamental steps of stellar nucleosynthesis, as it describes the formation of life-determining element of carbon, while it plays a key role in the evolution of Red Giant, accreting White Dwarfs and Neutron Stars. In this work we develop a generalized statistical theory for the 3α reaction, which is based on the use of the Imaginary Time Method, along with the semi-classical Hybrid α-Clustering (HαC) and Neck Model (NM) frameworks. …”
