Where planetary solids survive sublimation around young and hot white dwarfs
Dimitri Veras, Keiji Ohtsuki, Rafael Martinez-Brunner +2
All observed planetary systems orbiting single white dwarfs have lived through the hot stellar transition from an asymptotic giant branch star. In this post-nebular transition peri…
White dwarf planets in star clusters: gravitational scattering versus mass-loss effects
Richard J. Parker, Dimitri Veras
White dwarfs are unique laboratories for understanding the formation, evolution and survivability of planetary systems. Post-main sequence mass-loss will change planetary orbital p…
Size limits on tidal debris around white dwarfs: the km-size barrier
Jordan K. Steckloff, Dimitri Veras, Kathryn Volk
Compact disks of planetary debris orbiting white dwarfs provide a crucial window into our understanding of evolved planetary systems. The formation of these disks has been widely m…
DebrisWatch II: Digging deeper for geosynchronous debris
James A. Blake, Benjamin F. Cooke, Cristina Paragini +27
The geosynchronous (GSO) debris environment is continually evolving. Regular monitoring of the region is consequently of great importance, though the trade-off between coverage and…
Producing planetary debris exterior to white dwarf Roche radii through sublimative rotational fission
Dimitri Veras, Jordan K. Steckloff, Kathryn Volk
The majority of white dwarfs that host periodic transiting planetary debris do so at distances that exceed the rubble-pile Roche limit, in disagreement with canonical formation mod…
The evolution of exocomets and their source populations
Alexander J. Mustill, Tim Pearce, Michele Bannister +12
We review the current state of knowledge of the long-term evolution of the small bodies that give rise to comets and exocomets, as well as their reservoirs. The active cometary pha…
Exocometary physics: material release and tails
Théo Vrignaud, Dennis Bodewits, Jake Hanlon +5
Despite decades of observations, the physical processes governing mass loss from small bodies beyond our Solar System remain poorly constrained. These exocomets are often treated a…
The Future of Evolved Planetary Systems
Roberto Raddi, Anna F. Pala, Alberto Rebassa-Mansergas +19
Understanding the formation, evolution, and chemical diversity of exoplanets are now central areas of astrophysics research. White dwarfs provide a uniquely sensitive laboratory fo…
The Origins & Reservoirs of Exocomets
Michele Bannister, Susanne Pfalzner, Tim Pearce +11
Small bodies exist in distinct populations within their planetary systems. These reservoir populations hold a range of compositions, which to first order are dependent on formation…
Discovery of an icy and nitrogen-rich extrasolar planetesimal
Snehalata Sahu, Boris T. Gänsicke, Jamie T. Williams +7
White dwarfs accreting planetary debris provide detailed insight into the bulk composition of rocky exo-planetesimals. However, only one Kuiper-Belt analogue has been identified in…
Transiting Planetary Debris near the Roche Limit of a White Dwarf on a 4.97hr Orbit -- and its Vanishing
Joseph A. Guidry, Zachary P. Vanderbosch, J. J. Hermes +9
We present the discovery of deep, irregular, periodic transits towards the white dwarf ZTFJ19444557 using follow-up time-series photometry and spectroscopy from Palomar, Kec…
Bounding destruction timescales of minor planets orbiting white dwarfs with the sesquinary catastrophe
Dimitri Veras, Matija Ćuk
Dynamical activity attributed to the destruction of minor planets orbiting white dwarfs has now been photometrically monitored in individual systems for up to one decade, long enou…
Resupplying planetary debris to old white dwarfs with supernova blast waves
Dimitri Veras
One challenge with explaining how high levels of planetary debris can enrich, or "pollute", old (3 Gyr) and very old (10 Gyr) white dwarfs is that debris reservoirs dep…
Characterizing planetary material accreted by cool helium atmosphere white dwarfs using an exponentially decaying disc model
Mairi W. O'Brien, Pier-Emmanuel Tremblay, Beth L. Klein +5
We present Keck High Resolution Echelle Spectrometer (HIRES) observations and model atmosphere analysis for two nearby, cool, helium-dominated atmosphere white dwarfs that have bee…
The dearth of high-mass hydrogen-atmosphere metal-polluted white dwarfs within 40 pc
Tim Cunningham, Pier-Emmanuel Tremblay, Mairi O'Brien +7
We present a population synthesis model which addresses the different mass distributions of the metal-polluted and non-metal-polluted hydrogen-atmosphere white dwarfs identified in…
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 evolution and delivery of rocky extra-solar materials to white dwarfs
Dimitri Veras, Alexander J. Mustill, Amy Bonsor
Understanding stellar evolution and its effect on planetary systems is crucial for correctly interpreting the chemical constraints of exo-planetary material that can be given to us…
