Dynamical masses across the Hertzsprung-Russell diagram
Hsiang-Chih Hwang, Yuan-Sen Ting, Sihao Cheng +1
We infer the dynamical masses of stars across the Hertzsprung-Russell (H-R) diagram using wide binaries from the Gaia survey. Gaia's high-precision astrometry measures the wide bin…
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…
A Gravitational Redshift Measurement of the White Dwarf Mass-Radius Relation
Vedant Chandra, Hsiang-Chih Hwang, Nadia L. Zakamska +1
The mass-radius relation of white dwarfs is largely determined by the equation of state of degenerate electrons, which causes the stellar radius to decrease as mass increases. Here…
Forever young white dwarfs: when stellar ageing stops
María E. Camisassa, Leandro G. Althaus, Santiago Torres +5
White dwarf stars are the most common end point of stellar evolution. Of special interest are the ultramassive white dwarfs, as they are related to type Ia Supernovae explosions, m…
Carbon star formation as seen through the non-monotonic initial-final mass relation
Paola Marigo, Jeffrey D. Cummings, Jason Lee Curtis +13
The initial-final mass relation (IFMR) links the birth mass of a star to the mass of the compact remnant left at its death. While the relevance of the IFMR across astrophysics is u…
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…
