Velocity-imaging the rapidly precessing planetary disc around the white dwarf HE 1349-2305 using Doppler tomography
Christopher J. Manser, Erik Dennihy, Boris T. Gänsicke +11
The presence of planetary material in white dwarf atmospheres, thought to be accreted from a dusty debris disc produced via the tidal disruption of a planetesimal, is common. Appro…
Relentless and Complex Transits from a Planetesimal Debris Disk
J. Farihi, J. J. Hermes, T. R. Marsh +11
This article reports quasi-continuous transiting events towards WD 1054-226 at d=36.2 pc and V=16.0 mag, based on simultaneous, high-cadence, multi-wavelength imaging photometry us…
Collisions in a gas-rich white dwarf planetary debris disc
Andrew Swan, Scott J. Kenyon, Jay Farihi +5
WD 0145+234 is a white dwarf that is accreting metals from a circumstellar disc of planetary material. It has exhibited a substantial and sustained increase in 3-5 micron flux sinc…
Recurring Planetary Debris Transits and Circumstellar Gas around White Dwarf ZTF J03281219
Zachary P. Vanderbosch, Saul Rappaport, Joseph A. Guidry +14
We present follow-up photometry and spectroscopy of ZTF J03281219 strengthening its status as a white dwarf exhibiting transiting planetary debris. Using TESS and Zwicky Transie…
Five New Post-Main-Sequence Debris Disks with Gaseous Emission
Erik Dennihy, Siyi Xu, Samuel Lai +13
Observations of debris disks, the products of the collisional evolution of rocky planetesimals, can be used to trace planetary activity across a wide range of stellar types. The mo…
The Planets around the Post-Common Envelope Binary NN Serpentis
F. V. Hessman, K. Beuermann, S. Dreizler +10
We have detected 2 circumbinary planets around the close binary system NN Serpentis using the orbital time delay effect measured via the sharp eclipses of the white dwarf primary.…
