Multi-Gigayear White Dwarf Cooling Delays from Clustering-Enhanced Gravitational Sedimentation
Evan B. Bauer, Josiah Schwab, Lars Bildsten +1
Cooling white dwarfs (WDs) can yield accurate ages when theoretical cooling models fully account for the physics of the dense plasma of WD interiors. We use MESA to investigate coo…
Two delays in white dwarf evolution revealed by Gaia
Sihao Cheng
By comparing two age indicators of high-mass white dwarfs derived from Gaia data, two discoveries have been made recently: one is the existence of a cooling anomaly that produces t…
A cooling anomaly of high-mass white dwarfs
Sihao Cheng, Jeffrey D. Cummings, Brice Ménard
Recently, the power of Gaia data has revealed an enhancement of high-mass white dwarfs (WDs) on the Hertzsprung--Russell diagram, called the Q branch. This branch is located at the…
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…
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…
Do Transformers Have the Ability for Periodicity Generalization?
Huanyu Liu, Ge Li, Yihong Dong +7
Large language models (LLMs) based on the Transformer have demonstrated strong performance across diverse tasks. However, current models still exhibit substantial limitations in ou…
