Impact of Decay-Chain Feeding by Long-Lived Heavy Nuclei on Nuclear Cosmochronology
Qiu-Hong Chen, Meng-Hua Chen, Xianlin Yang +1
Nuclear cosmochronology provides an independent method for determining the ages of astrophysical objects without relying on Galactic chemical evolution models. Long-lived radioacti…
-equivariant minimal Lagrangian surfaces in the complex quadric and the complex hyperbolic quadric
Sihao Zeng
We study global and variational properties of -equivariant minimal Lagrangian surfaces in the complex quadric and the complex hyperbolic quadric arising fr…
Kilonova Emission from Neutron Star Mergers with Different Equations of State
Wu-Zimo Qiumu, Meng-Hua Chen, Qiu-Hong Chen +1
Kilonova is an optical-infrared transient powered by the radioactive decay of heavy nuclei from binary neutron star mergers. Its observational characteristics depend on the mass an…
Impact of nuclear mass models on -process nucleosynthesis and heavy element abundances in -process enhanced metal-poor stars
Meng-Hua Chen, Li-Xin Li, En-Wei Liang +1
Due to the lack of experimental data on extremely neutron-rich nuclei, theoretical values derived from nuclear physics models are essential for the rapid neutron capture process ($…
Origin of Black Hole Spin in Lower-Mass-Gap Black Hole-Neutron Star Binaries
Ying Qin, Zhen-Han-Tao Wang, Georges Meynet +8
During the fourth observing run, the LIGO-Virgo-KAGRA Collaboration reported the detection of a coalescing compact binary (GW230529181500) with component masses estimated at…
Radioactive Gamma-Ray Lines from Long-lived Neutron Star Merger Remnants
Meng-Hua Chen, Li-Xin Li, En-Wei Liang
The observation of a kilonova AT2017gfo associated with the gravitational wave event GW170817 provides the first strong evidence that neutron star mergers are dominant contributors…
The Energy Sources, the Physical Properties, and the Mass-loss History of SN 2017dio
Deng-Wang Shi, Shan-Qin Wang, Wen-Pei Gan +1
We study the energy sources, the physical properties of the ejecta and the circumstellar medium (CSM), as well as the mass-loss history of the progenitor of SN 2017dio which is a b…
A Channel to Form Fast-spinning Black Hole-Neutron Star Binary Mergers as Multimessenger Sources. II. Accretion-induced Spin-up
Zhen-Han-Tao Wang, Rui-Chong Hu, Ying Qin +7
In this work, we investigate an alternative channel for the formation of fast-spinning black hole-neutron star (BHNS) binaries, in which super-Eddington accretion is expected to oc…
Ejecta-circumstellar medium interaction in high-density environment contribution to kilonova emission: Application to GRB 191019A
Suo-Ning Wang, Hou-Jun Lü, Yong Yuan +4
The nearby long-duration GRB 191019A recently detected by Swift lacks an associated supernova and belongs to a host galaxy with little star formation activity, suggesting that the…
Neutron Star Mergers as the Dominant Contributor to the Production of Heavy -Process Elements
Meng-Hua Chen, Li-Xin Li, Qiu-Hong Chen +2
The discovery of the radioactively powered kilonova AT2017gfo, associated with the short-duration gamma-ray burst GRB 170817A and the gravitational wave source GW170817, has provid…
Radioactive Decay of Specific Heavy Elements as an Energy Source for Late-Time Kilonovae and Potential JWST Observations
Meng-Hua Chen, En-Wei Liang
Revealing the temporal evolution of individual heavy elements synthesized in the merger ejecta from binary neutron star mergers not only improves our understanding of the origin of…
