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…
Semi-supervised Spectral Classification of DESI White Dwarfs by Dimensionality Reduction
Xander Byrne, Amy Bonsor, Laura K. Rogers +1
As a new generation of large-sky spectroscopic surveys comes online, the enormous data volume poses unprecedented challenges in classifying spectra. Modern unsupervised techniques…
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…
The frequency of metal-enrichment of cool helium-atmosphere white dwarfs using the DESI Early Data Release
Christopher J. Manser, Boris T. Gänsicke, Paula Izquierdo +35
There is overwhelming evidence that white dwarfs host planetary systems; revealed by the presence, disruption, and accretion of planetary bodies. A lower limit on the frequency of…
The DESI Early Data Release White Dwarf Catalogue
Christopher J. Manser, Paula Izquierdo, Boris T. Gänsicke +51
The Early Data Release (EDR) of the Dark Energy Spectroscopic Instrument (DESI) comprises spectroscopy obtained from 2020 December 14 to 2021 June 10. White dwarfs were targeted by…
An HST COS ultra-violet spectroscopic survey of 311 DA white dwarfs.I. Fundamental parameters and comparative studies
Snehalata Sahu, Boris T. Gaensicke, Pier-Emmanuel Tremblay +8
White dwarf studies carry significant implications across multiple fields of astrophysics, including exoplanets, supernova explosions, and cosmological investigations. Thus, accura…
