A Test of Substellar Evolutionary Models with High-Precision Ages from Asteroseismology and Gyrochronology for the Benchmark System HR 7672AB
Yaguang Li, Michael C. Liu, Trent J. Dupuy +35
We present high-precision measurements for HR~7672AB, composed of a Sun-like (G0V) star and an L~dwarf companion. Three nights of precise (70 cm/s) radial velocity (RV) asteroseism…
The Hybrid Debris Disk Host Star HD 21997 is a High-Frequency Delta Scuti Pulsator
Aldo G. Sepulveda, Timothy R. Bedding, Simon J. Murphy +3
HD 21997 is host to a prototypical "hybrid" debris disk characterized by debris disk-like dust properties and a CO gas mass comparable to a protoplanetary disk. We use Transiting E…
Weakened Magnetic Braking in the Exoplanet Host Star 51 Peg
Travis S. Metcalfe, Klaus G. Strassmeier, Ilya V. Ilyin +11
The consistently low activity level of the old solar analog 51 Peg not only facilitated the discovery of the first hot Jupiter, but also led to the suggestion that the star could b…
HIP 65426 is a High-Frequency Delta Scuti Pulsator in Plausible Spin-Orbit Alignment with its Directly Imaged Exoplanet
Aldo G. Sepulveda, Daniel Huber, Timothy R. Bedding +4
HIP 65426 hosts a young giant planet that has become the first exoplanet directly imaged with JWST. Using time-series photometry from the Transiting Exoplanet Survey Satellite (TES…
The Directly-Imaged Exoplanet Host Star 51 Eridani is a Gamma Doradus Pulsator
Aldo G. Sepulveda, Daniel Huber, Zhoujian Zhang +3
51 Eri is well known for hosting a directly-imaged giant planet and for its membership to the Pictoris moving group. Using two-minute cadence photometry from the Transiting Exo…
Dynamical Mass of the Exoplanet Host Star HR 8799
Aldo G. Sepulveda, Brendan P. Bowler
HR 8799 is a young A5/F0 star hosting four directly imaged giant planets at wide separations (16-78 au) which are undergoing orbital motion and have been continuously monitor…
The REASONS Survey: Resolved Millimeter Observations of a Large Debris Disk Around the Nearby F Star HD 170773
Aldo G. Sepulveda, Luca Matra, Grant M. Kennedy +15
Debris disks are extrasolar analogs to our own Kuiper Belt and they are detected around at least 17% of nearby Sun-like stars. The morphology and dynamics of a disk encode informat…
