Effects of vertical advection on multimessenger signatures of black hole neutrino-dominated accretion flows in compact binary coalescences
Bing-Guang Chen, Tong Liu, Yan-Qing Qi +5
In the coalescence events of binary neutron star (NS) or a black hole (BH) and an NS, a BH hyperaccretion disk might be eventually formed. At very high mass accretion rates, MeV ne…
The Nearest Neutron Star Candidate in a Binary Revealed by Optical Time-domain Surveys
Ling-Lin Zheng, Mouyuan Sun, Wei-Min Gu +19
The near-Earth (within pc) supernova explosions in the past several million years can cause the global deposition of radioactive elements (e.g., Fe) on Earth. The…
Compact Object Candidates with K/M-dwarf Companions from LAMOST Low-resolution Survey
Hui-Jun Mu, Wei-Min Gu, Tuan Yi +6
Searching for compact objects (black holes, neutron stars, or white dwarfs) in the Milky Way is essential for understanding the stellar evolution history, the physics of compact ob…
One-off and Repeating Fast Radio Bursts: A Statistical Analysis
Hao-Yan Chen, Wei-Min Gu, Mouyuan Sun +1
According to the number of detected bursts, fast radio bursts (FRBs) can be classified into two categories, i.e., one-off FRBs and repeating ones. We make a statistical comparison…
A White Dwarf-Main Sequence Binary Unveiled by Time-Domain Observations from LAMOST and TESS
Ling-Lin Zheng, Wei-Min Gu, Mouyuan Sun +16
We report a single-lined white dwarf-main sequence binary system, LAMOST J172900.17+652952.8, which is discovered by LAMOST's medium resolution time-domain surveys. The radial velo…
A long-period pre-ELM system discovered from LAMOST medium-resolution survey
Zhi-Xiang Zhang, Ling-Lin Zheng, Wei-Min Gu +16
We present LAMOST~J041920.07+072545.4 (hereafter J0419), a close binary consisting of a bloated extremely low mass pre-white dwarf (pre-ELM WD) and a compact object with an orbital…
A dynamically discovered and characterized non-accreting neutron star -- M dwarf binary candidate
Tuan Yi, Wei-Min Gu, Zhi-Xiang Zhang +26
Optical time-domain surveys can unveil and characterize exciting but less-explored non-accreting and/or non-beaming neutron stars (NS) in binaries. Here we report the discovery of…
Searching for compact objects in binaries with Gaia DR3
Jin-Bo Fu, Wei-Min Gu, Zhi-Xiang Zhang +4
We search for compact objects in binaries based on Gaia DR3. A sample of ten targets is derived under the conditions: radial velocity variable, low temperature ($T_{\rm eff} < 6000…
Effects of Gravitational Wave Radiation of Eccentric Neutron Star-White Dwarf Binaries on the Periodic Activity of Fast Radio Burst Sources
Yi-Qing Lin, Hao-Yan Chen, Wei-Min Gu +1
We revisit the eccentric neutron star (NS)-white dwarf (WD) binary model for the periodic activity of fast radio burst (FRB) sources, by including the effects of gravitational wave…
