Serendipitous Discovery of Nine White Dwarfs With Gaseous Debris Disks
Carl Melis, B. Klein, A. E. Doyle +3
Optical spectroscopic observations of white dwarf stars selected from catalogs based on the Gaia DR2 database reveal nine new gaseous debris disks that orbit single white dwarf sta…
A Giant Planet Candidate Transiting a White Dwarf
Andrew Vanderburg, Saul A. Rappaport, Siyi Xu +61
Astronomers have discovered thousands of planets outside the solar system, most of which orbit stars that will eventually evolve into red giants and then into white dwarfs. During…
Atmospheric Temperature Inversions and He I 5876 Core Profile Structure in White Dwarfs
Beth Klein, Simon Blouin, Diego Romani +7
We report distinctive core profiles in the strongest optical helium line, He I 5876, from high-resolution high-sensitivity observations of spectral type DB white dwarfs. By analyzi…
Dynamical masses for the Pleiades binary system HII-2147
Guillermo Torres, Carl Melis, Adam L. Kraus +3
We report our long-term spectroscopic monitoring of the Pleiades member HII-2147, which has previously been spatially resolved at radio wavelengths in VLBI observations. It has als…
Mid-infrared Studies of HD 113766 and HD 172555: Assessing Variability in the Terrestrial Zone of Young Exoplanetary Systems
Kate Y. L. Su, George H. Rieke, Carl Melis +4
We present multi-epoch infrared photometry and spectroscopy obtained with warm Spitzer, Subaru and SOFIA to assess variability for the young (20 Myr) and dusty debris systems…
