A New Approach to Modeling Line Shapes with Quasi-H Satellites in Stellar Atmospheres
Jackson R. White, Thomas A. Gomez, Mark C. Zammit +6
Theoretical spectral line shapes describe the distribution of opacity due to bound electronic transitions in hot dense plasmas and are used to fit emergent spectra from many astrop…
Hunting for Polluted White Dwarfs and Other Treasures with Gaia XP Spectra and Unsupervised Machine Learning
Malia L. Kao, Keith Hawkins, Laura K. Rogers +5
White dwarfs (WDs) polluted by exoplanetary material provide the unprecedented opportunity to directly observe the interiors of exoplanets. However, spectroscopic surveys are often…
Kepler and TESS Observations of PG 1159-035
Gabriela Oliveira da Rosa, S. O. Kepler, Alejandro H. Córsico +11
PG 1159-035 is the prototype of the DOV hot pre-white dwarf pulsators. It was observed during the Kepler satellite K2 mission for 69 days in 59 s cadence mode and by the TESS satel…
The Pulsating Helium-Atmosphere White Dwarfs I: New DBVs from the Sloan Digital Sky Survey
Zachary P. Vanderbosch, J. J. Hermes, Don E. Winget +4
We present a dedicated search for new pulsating helium-atmosphere (DBV) white dwarfs from the Sloan Digital Sky Survey using the McDonald 2.1m Otto Struve Telescope. In total we ob…
Pulsating hydrogen-deficient white dwarfs and pre-white dwarfs observed with {\it TESS}: III. Asteroseismology of the DBV star GD 358
Alejandro H. Córsico, Murat Uzundag, S. O. Kepler +14
The collection of high-quality photometric data by space telescopes is revolutionizing the area of white-dwarf asteroseismology. Among the different kinds of pulsating white dwarfs…
I Spy Transits and Pulsations: Empirical Variability in White Dwarfs Using Gaia and the Zwicky Transient Facility
Joseph A. Guidry, Zachary P. Vanderbosch, J. J. Hermes +13
We present a novel method to detect variable astrophysical objects and transient phenomena using anomalous excess scatter in repeated measurements from public catalogs of Gaia DR2…
