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…
Host-star and exoplanet compositions: a pilot study usinga wide binary with a polluted white dwarf
Amy Bonsor, Paula Jofre, Oliver Shorttle +3
Planets and stars ultimately form out of the collapse of the same cloud of gas. Whilst planets, and planetary bodies, readily loose volatiles, a common hypothesis is that they reta…
Serendipitous discovery of a dusty disc around WDJ181417.84-735459.83
E. González Egea, R. Raddi, D. Koester +8
Spectroscopic observations of white dwarfs reveal that many of them are polluted by exoplanetary material, whose bulk composition can be uniquely probed this way. We present a spec…
Exocomets from a Solar System Perspective
Paul A. Strøm, Dennis Bodewits, Matthew M. Knight +24
Exocomets are small bodies releasing gas and dust which orbit stars other than the Sun. Their existence was first inferred from the detection of variable absorption features in ste…
Near-infrared variability in dusty white dwarfs: tracing the accretion of planetary material
Laura K. Rogers, Siyi Xu, Amy Bonsor +4
The inwards scattering of planetesimals towards white dwarfs is expected to be a stochastic process with variability on human time-scales. The planetesimals tidally disrupt at the…
Dust Production and Depletion in Evolved Planetary Systems
J. Farihi, R. van Lieshout, P. W. Cauley +15
The infrared dust emission from the white dwarf GD 56 is found to rise and fall by 20% peak-to-peak over 11.2 yr, and is consistent with ongoing dust production and depletion. It i…
