Infrared Excesses around Bright White Dwarfs from Gaia and unWISE. II
Samuel Lai, Erik Dennihy, Siyi Xu +7
Infrared excesses around white dwarf stars indicate the presence of various astrophysical objects of interest, including companions and debris disks. In this second paper of a seri…
An Isolated White Dwarf with 317-Second Rotation and Magnetic Emission
Joshua S. Reding, J. J. Hermes, Z. Vanderbosch +5
We report the discovery of short-period photometric variability and modulated Zeeman-split hydrogen emission in SDSSJ125230.93-023417.72 (EPIC 228939929), a variable white dwarf st…
A Word to the WISE: Confusion is Unavoidable for WISE-selected Infrared Excesses
Erik Dennihy, Jay Farihi, Nicola Pietro Gentile Fusillo +1
Stars with excess infrared radiation from circumstellar dust are invaluable for studies of exoplanetary systems, informing our understanding on processes of planet formation and de…
A White Dwarf with Transiting Circumstellar Material Far Outside the Roche Limit
Z. Vanderbosch, J. J. Hermes, E. Dennihy +9
We report the discovery of a white dwarf exhibiting deep, irregularly shaped transits, indicative of circumstellar planetary debris. Using Zwicky Transient Facility DR2 photometry…
A Volume Limited Sample of Cataclysmic Variables from DR2: Space Density and Population Properties
A. F. Pala, B. T. Gänsicke, E. Breedt +15
We present the first volume-limited sample of cataclysmic variables (CVs), selected using the accurate parallaxes provided by the second data release (DR2) of the ESA $\mathit{Gaia…
Dusty Exoplanetary Debris Disks in the Single-Temperature Blackbody Plane
E. Dennihy, J. C. Clemens, B. H. Dunlap
We present a bulk sample analysis of the metal polluted white dwarfs which also host infrared bright dusty debris disks, known to be direct signatures of an active exoplanetary acc…
