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…
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…
A 15.7-Minute AM CVn Binary Discovered in K2
M. J. Green, J. J. Hermes, T. R. Marsh +14
We present the discovery of SDSS J135154.46-064309.0, a short-period variable observed using 30-minute cadence photometry in K2 Campaign 6. Follow-up spectroscopy and high-speed ph…
The first sub-70 minute non-interacting WD-BD system: EPIC212235321
S. L. Casewell, I. P. Braker, S. G. Parsons +9
We present the discovery of the shortest-period, non-interacting, white dwarf-brown dwarf post-common-envelope binary known. The K2 light curve shows the system, EPIC 21223532 has…
Rapid Evolution of the Gaseous Exoplanetary Debris Around the White Dwarf Star HE 1349--2305
E. Dennihy, J. C. Clemens, B. H. Dunlap +3
Observations of heavy metal pollution in white dwarf stars indicate that metal-rich planetesimals are frequently scattered into star-grazing orbits, tidally disrupted, and accreted…
