Dr. Judi Provencal
Judi is currently undertaking a project to narrow down the temperature of the hot edge of the Helium atmosphere pulsation instabililty strip.
Millie Dill
Millie studies two pulsating Hydrogen atmosphere pulsating white dwarfs, HL Tau 76 and EC 14012-1446. She has been studying 50 years of data on these stars, and hopes to undertake convective light curve fitting as she moves into a Ph.D. program.
Kaylee Grace (she/they)
Kaylee is currently studying pulsating helium atmosphere white dwarfs on the hot edge of the DBV instability strip. The location of the hot edge of the strip is unknown after the discovery of hot pulsator PG 0112+104. Using HST spectra of these hot DBs, Kaylee aims to determine their effective temperatures and surface gravities to determine the location of the blue edge. She also takes ground based observations of a number of DB/DBVs, including GD 358. Combining 35 years of archival data with three years of TESS data and recent ground-based data taken by herself and collaborators she is working to create updated asteroseismic and spectral models of the star.
Zach Savery (he/him)
Zach’s research is currently focused on studying the DAV pulsating white dwarf, G29-38. G29-38 is an interesting object for not only being a pulsating white dwarf, but it’s also one of the first white dwarfs with a known debris disk. This research has involved studying ground and spaced-based optical lightcurves of G29-38, spanning from 1975 to 2023. The ground-based observations have involved the use of the Mount Cuba Observatory, the SARA Observatories, and PJMO, among many others. The space-based observations have been made by TESS.
