White Dwarf Merger Remnants with Cooling Delays on the Q Branch Lack Strong Magnetism
Lou Baya Ould Rouis, J. J. Hermes, Joseph A. Guidry +8
A population of anomalous ultra-massive white dwarfs discovered with Gaia, often referred to as the Q branch, show high (multi-Gyr) cooling delays produced by exotic physical mecha…
Discovery of a dwarf planet candidate in an extremely wide orbit: 2017 OF201
Sihao Cheng, Jiaxuan Li, Eritas Yang
We report the discovery of a dwarf planet candidate, 2017 OF201, currently located at a distance of 90 au. Its orbit is extremely wide and extends to the inner Oort cloud, with a s…
Buoyant crystals halt the cooling of white dwarf stars
Antoine Bédard, Simon Blouin, Sihao Cheng
White dwarfs are stellar remnants devoid of a nuclear energy source, gradually cooling over billions of years and eventually freezing into a solid state from the inside out. Recent…
A new code for low-resolution spectral identification of white dwarf binary candidates
Genghao Liu, Baitian Tang, Liangliang Ren +7
Close white dwarf binaries (CWDBs) are considered to be progenitors of several exotic astronomical phenomena (e.g., type Ia supernovae, cataclysmic variables). These violent events…
A Systematic Search for Short-period Close White Dwarf Binary Candidates Based on Gaia EDR3 Catalog and Zwicky Transient Facility Data
Liangliang Ren, Chengyuan Li, Bo Ma +4
Galactic short-period close white dwarf binaries (CWDBs) are important objects for space-borne gravitational-wave (GW) detectors in the millihertz frequency bands. Due to the intri…
