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…
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…
Identifying Periodic Variable Stars and Eclipsing Binary Systems with Long-Term Las Cumbres Observatory Photometric Monitoring of ZTF J0139+5245
Aniket Sanghi, Zachary P. Vanderbosch, Michael H. Montgomery
We present the results of our search for variable stars using the long-term Las Cumbres Observatory (LCO) monitoring of white dwarf ZTF J0139+5245 with the two 1.0-m telescope node…
On The Impact Of 22Ne On The Pulsation Periods Of Carbon-Oxygen White Dwarfs With Helium Dominated Atmospheres
Morgan T. Chidester, F. X. Timmes, Josiah Schwab +6
We explore changes in the adiabatic low-order g-mode pulsation periods of 0.526, 0.560, and 0.729 M carbon-oxygen white dwarf models with helium-dominated envelopes due to…
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…
