Lithium pollution of a white dwarf records the accretion of an extrasolar planetesimal
Benjamin C. Kaiser, J. Christopher Clemens, Simon Blouin +4
Tidal disruption and subsequent accretion of planetesimals by white dwarfs can reveal the elemental abundances of rocky bodies in exoplanetary systems. Those abundances provide inf…
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…
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…
Photometric and Spectroscopic Properties of Type Ia Supernova 2018oh with Early Excess Emission from the 2 Observations
W. Li, X. Wang, J. Vinkó +160
Supernova (SN) 2018oh (ASASSN-18bt) is the first spectroscopically-confirmed type Ia supernova (SN Ia) observed in the field. The data revealed an excess emission…
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…
