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. …”

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. …”

Predicting the Rate of Fast Radio Bursts in Globular Clusters from Binary Black Hole Observations
Published 2025-01-01“…A potential explanation is super-Chandrasekhar binary white dwarf (BWD) coalescences, which may produce FRB-emitting neutron stars. GCs can also give rise to binary black hole (BBH) mergers detectable with gravitational waves, and the BWD coalescence rate from GCs is correlated with their BBH merger rate. …”

The stability of anisotropic compact stars influenced by dark matter under teleparallel gravity: an extended gravitational deformation approach
Published 2025-02-01“…To validate our findings, we compare our model predictions with observational constraints, including GW190814 (with a mass range of $$2.5-2.67 M_{\odot }$$ 2.5 - 2.67 M ⊙ ) and neutron stars (NSTRs) such as EXO 1785-248 [mass= $$1.3_{-0.2}^{+0.2}~M_{\odot }$$ 1 . 3 - 0.2 + 0.2 M ⊙ ], 4U 1608-52 [mass= $$1.74_{-0.14}^{+0.14}~M_{\odot }$$ 1 . 74 - 0.14 + 0.14 M ⊙ ], and PSR J0952-0607 [mass= $$2.35_{-0.17}^{+0.17}~M_{\odot }$$ 2 . 35 - 0.17 + 0.17 M ⊙ ]. …”
