A 1.9 solar-mass neutron star candidate in a 2-year orbit
Published 2024-04-01“…The companion is most likely a massive neutron star: the only viable alternative is two massive white dwarfs in a close binary, but this scenario is disfavored on evolutionary grounds. …”

Discovery and Timing of Millisecond Pulsars in the Globular Cluster M5 with FAST and Arecibo
Published 2023-01-01“…The binary pulsars M5D, M5E, and M5F are confirmed to be in low-eccentricity binary systems, the low-mass companions of which are newly identified to be He white dwarfs using Hubble Space Telescope data. Four pulsars are also found to be associated with X-ray sources. …”

Spectroscopic Follow-up on Potential Magnetic Cataclysmic Variables
Published 2024-01-01“…Spectroscopic observations of nine cataclysmic variables that have been postulated to contain magnetic white dwarfs were obtained to further characterize their classifications, orbital parameters, inclinations, and/or accretion properties. …”

Mass Distribution for Single-lined Hot Subdwarf Stars in LAMOST
Published 2023-01-01“…By comparing the observed mass distributions to the predictions of different formation scenarios, we concluded that the binary merger channel, including two helium white dwarfs (He-WDs) and He-WD + main-sequence mergers, cannot be the only main formation channel for He-rich hot subdwarfs, and other formation channels, such as the surviving companions from Type Ia supernovae, could also make impacts on producing this special population, especially for He-rich hot subdwarfs with masses less than 0.44 M _⊙ . …”

Induced Gravitational Collapse, Binary-Driven Hypernovae, Long Gramma-ray Bursts and Their Connection with Short Gamma-ray Bursts
Published 2019-05-01“…The binary components involve carbon-oxygen cores (CO<inline-formula> <math display="inline"> <semantics> <msub> <mrow></mrow> <mi>core</mi> </msub> </semantics> </math> </inline-formula>), neutron stars (NSs), black holes (BHs), and white dwarfs (WDs). We review here the salient features of the specific class of binary-driven hypernovae (BdHNe) within the induced gravitational collapse (IGC) scenario for the explanation of the long GRBs. …”
