HD 38973 b -- a cold Saturn orbiting a Sun-like star
Adriana Errico, Robert A. Wittenmyer, Jonathan Horner +2
We report the detection of a long-period companion to the nearby solar-type star HD\,38973 using precision radial-velocity measurements. The radial-velocity data reveal a coherent…
A Cool Earth-sized Planet Candidate Transiting a Tenth Magnitude K-dwarf From K2
Alexander Venner, Andrew Vanderburg, Chelsea X. Huang +7
The transit method is currently one of our best means for the detection of potentially habitable "Earth-like" exoplanets. In principle, given sufficiently high photometric precisio…
RVTESS I: Modeling Asteroseismic Signals with Simultaneous Photometry and RVs
Jiaxin Tang, Sharon X. Wang, Yaguang Li +22
Detecting small planets via the radial velocity method remains challenged by signals induced by stellar variability, versus the effects of the planet(s). Here, we explore using Gau…
SPORES-HWO. II. Companion Mass Limits and Updated Planet Properties for 120 Future Exoplanet Imaging Targets from 35 yr of Precise Doppler Monitoring
Caleb K. Harada, Courtney D. Dressing, Emma V. Turtelboom +17
A goal of the future Habitable Worlds Observatory (HWO) is to directly image and spectroscopically characterize true Earth-analogs. However, if a large fraction of HWO target stars…
The Spin-orbit alignment of two short period eclipsing binary systems
Tony Wells, B. C. Addison, R. A. Wittenmyer +8
We present a joint analysis of TESS photometry and radial velocity measurements obtained from the Minerva-Australis facility for two short-period eclipsing binaries, TIC 48227288 a…
Sub-Jupiter Gas Giants Orbiting Giant Stars Uncovered using a Bayesian Framework
J. S. Jenkins, M. I. Jones, J. I. Vines +6
Giant stars have been shown to be rich hunting grounds for those aiming to detect giant planets orbiting beyond ~0.5 AU. Here we present two planetary systems around bright giant s…
