Modeling Circumstellar Gas Emission around a White Dwarf Using Cloudy
Siyi Xu, Sherry Yeh, Laura. K. Rogers +9
The chemical composition of an extrasolar planet is fundamental to its formation, evolution and habitability. In this study, we explore a new way to measure the chemical compositio…
WD0141-675: A case study on how to follow-up astrometric planet candidates around white dwarfs
Laura K. Rogers, John Debes, Richard J. Anslow +22
This work combines spectroscopic and photometric data of the polluted white dwarf WD0141-675 which has a now retracted astrometric super-Jupiter candidate and investigates the most…
An emerging and enigmatic spectral class of isolated DAe white dwarfs
Abbigail K. Elms, Pier-Emmanuel Tremblay, Boris T. Gänsicke +9
Two recently discovered white dwarfs, WDJ041246.84754942.26 and WDJ165335.21100116.33, exhibit H and H Balmer line emission similar to stars in the emerging DAHe class,…
Disk or Companion: Characterizing Excess Infrared Flux in Seven White Dwarf Systems with Near-Infrared Spectroscopy
Dylan Owens, Siyi Xu, Elena Manjavacas +7
Excess infrared flux from white dwarf stars is likely to arise from a dusty debris disk or a cool companion. In this work, we present near-infrared spectroscopic observations with…
Faro: A framework for measuring the scientific performance of petascale Rubin Observatory data products
Leanne P. Guy, Keith Bechtol, Jeffrey L. Carlin +14
The Vera C. Rubin Observatory will advance many areas of astronomy over the next decade with its unique wide-fast-deep multi-color imaging survey, the Legacy Survey of Space and Ti…
Understanding Systematics in ZZ Ceti Model Fitting to Enable Differential Seismology
J. T. Fuchs, Bart H. Dunlap, J. C. Clemens +3
We are conducting a large spectroscopic survey of over 130 Southern ZZ Cetis with the Goodman Spectrograph on the SOAR Telescope. Because it employs a single instrument with high U…
