The NEID Earth Twin Survey. I. Confirmation of a 31-day planet orbiting HD 86728

Arvind F. Gupta, Jacob K. Luhn, Jason T. Wright +21

With close to three years of observations in hand, the NEID Earth Twin Survey (NETS) is starting to unearth new astrophysical signals for a curated sample of bright, radial velocit…

The HD 191939 Exoplanet System is Well-Aligned and Flat

Jack Lubin, Erik A. Petigura, Judah Van Zandt +25

We report the sky-projected spin-orbit angle for HD 191939 b, the innermost planet in a 6 planet system, using Keck/KPF to detect the Rossiter-McLaughlin (RM) effect. Planet b…

Data-Driven Modeling of Telluric Features and Stellar Variability with StellarSpectraObservationFitting.jl

Christian Gilbertson, Eric B. Ford, Samuel Halverson +11

A significant barrier to achieving the radial velocity (RV) measurement accuracy and precision required to characterize terrestrial mass exoplanets is the existence of time-variabl…

Searching for GEMS: Characterizing Six Giant Planets around Cool Dwarfs

Shubham Kanodia, Arvind F. Gupta, Caleb I. Canas +42

Transiting giant exoplanets around M-dwarf stars (GEMS) are rare, owing to the low-mass host stars. However, the all-sky coverage of TESS has enabled the detection of an increasing…

Asteroseismology of the Nearby K-Dwarf Draconis using the Keck Planet Finder and TESS

Marc Hon, Daniel Huber, Yaguang Li +76

Asteroseismology of dwarf stars cooler than the Sun is very challenging due to the low amplitudes and rapid timescales of oscillations. Here, we present the asteroseismic detection…

Quiet Please: Detrending Radial Velocity Variations from Stellar Activity with a Physically Motivated Spot Model

Jared C. Siegel, Samuel Halverson, Jacob K. Luhn +15

For solar-type stars, spots and their associated magnetic regions induce radial velocity perturbations through the Doppler rotation signal and the suppression of convective blueshi…
