Evidence for Misalignment Between Debris Disks and Their Host Stars
Spencer A. Hurt, Meredith A. MacGregor
We place lower limits on the obliquities between debris disks and their host stars for 31 systems by comparing their disk and stellar inclinations. While previous studies did not f…
The apparent absence of forward scattering in the HD 53143 debris disk
Christopher C. Stark, Bin Ren, Meredith A. MacGregor +5
HD 53143 is a mature Sun-like star and host to a broad disk of dusty debris, including a cold outer ring of planetesimals near 90 AU. Unlike most other inclined debris disks imaged…
Planet Search with the Keck/NIRC2 Vortex Coronagraph in Ms-band for Vega
Bin B. Ren, Nicole L. Wallack, Spencer A. Hurt +12
Gaps in circumstellar disks can signal the existence of planetary perturbers, making such systems preferred targets for direct imaging observations of exoplanets. Being one of the…
ALMA Images the Eccentric HD 53143 Debris Disk
Meredith A. MacGregor, Spencer A. Hurt, Christopher C. Stark +6
We present ALMA 1.3 mm observations of the HD~53143 debris disk - the first infrared or millimeter image produced of this ~1 Gyr-old solar-analogue. Previous HST STIS coronagraphic…
Confirmation of the Long-Period Planet Orbiting Gliese 411 and the Detection of a New Planet Candidate
Spencer A. Hurt, Benjamin Fulton, Howard Isaacson +4
We perform a detailed characterization of the planetary system orbiting the bright, nearby M dwarf Gliese 411 using radial velocities gathered by APF, HIRES, SOPHIE, and CARMENES.…
A decade of radial-velocity monitoring of Vega and new limits on the presence of planets
Spencer A. Hurt, Samuel N. Quinn, David W. Latham +7
We present an analysis of 1524 spectra of Vega spanning 10 years, in which we search for periodic radial velocity variations. A signal with a periodicity of 0.676 days and a semi-a…
