Simultaneous emission from dust and gas in the planetary debris orbiting a white dwarf
Laura K. Rogers, Christopher J. Manser, Amy Bonsor +11
There is increasing evidence for the presence and variability of circumstellar dust and gas around white dwarfs that are polluted with exoplanetary material, although the origin of…
The Origins of Lithium Enhancement in Polluted White Dwarfs
Benjamin C. Kaiser, J. Christopher Clemens, Simon Blouin +4
The bulk abundances of exoplanetesimals can be measured when they are accreted by white dwarfs. Recently, lithium from the accretion of exoplanetesimals was detected in relatively…
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…
