An Increase in Small-planet Occurrence with Metallicity for Late-type Dwarf Stars in the Kepler Field and Its Implications for Planet Formation
Cicero X. Lu, Kevin C. Schlaufman, Sihao Cheng
While it is well established that giant-planet occurrence rises rapidly with host star metallicity, it is not yet clear if small-planet occurrence around late-type dwarf stars depe…
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…
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…
