Distant White Dwarfs in the US Naval Observatory Flagstaff Station Parallax Sample
S. K. Leggett, P. Bergeron, John P. Subasavage +18
This paper presents new trigonometric parallaxes and proper motions for 214 stars. The measurements were made at the US Naval Observatory Flagstaff Station (NOFS) between 1989 and…
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…
Infrared Variability of Two Dusty White Dwarfs
Siyi Xu, Kate Y. L. Su, Laura Rogers +11
The most heavily polluted white dwarfs often show excess infrared radiation from circumstellar dust disks, which are modeled as a result of tidal disruption of extrasolar minor pla…
The Excited Spin State of 1I/2017 U1 `Oumuamua
Michael J. S. Belton, Olivier R. Hainaut, Karen J. Meech +15
We show that `Oumuamua's excited spin could be in a high energy LAM state, which implies that its shape could be far from the highly elongated shape found in previous studies. CLEA…
