Order-by-order Modeling of Exoplanet Radial Velocity Data

Zachary Langford, Cullen Blake, Samuel Halverson +12

Precise radial velocity (RV) measurements are a crucial tool for exoplanet discovery and characterization. Today, the majority of these measurements are derived from Echelle spectr…

Discovery of a Nearby Habitable Zone Super-Earth Candidate Amenable to Direct Imaging

Corey Beard, Paul Robertson, Jack Lubin +31

We present the discovery of GJ 251 c, a candidate super-Earth orbiting in the Habitable Zone (HZ) of its M dwarf host star. Using high-precision Habitable-zone Planet Finder (HPF)…

An Earth-Sized Planet in a 5.4h Orbit Around a Nearby K dwarf

Kaya Han Taş, Gudmundur Stefansson, Syarief N. M. Fariz +25

We present the discovery and confirmation of the ultra-short period (USP) planet TOI-2431 b orbiting a nearby ( pc) late K star ( = $4109 \pm 28 \, {\rm…

TOI-1259Ab: A Warm Jupiter Orbiting a K-dwarf White-Dwarf Binary is on a Well-aligned Orbit

Hugo Veldhuis, Juan I. Espinoza-Retamal, Gudmundur Stefansson +21

The evolution of one member of a stellar binary into a white dwarf has been proposed as a mechanism that triggers the formation of close-in gas giant planets. The star's asymmetric…

The NEID Earth Twin Survey. III. Survey Performance After Three Years on Sky

Arvind F. Gupta, Evan Fitzmaurice, Suvrath Mahadevan +22

The NEID Earth Twin Survey (NETS) has been delivering a rich set of precise radial velocity (RV) measurements for 41 bright, nearby main sequence stars. Here, we describe the statu…

The NEID Earth Twin Survey. II. Dynamical Masses in Seven High-acceleration Star Systems

Mark R. Giovinazzi, Cullen H. Blake, Paul Robertson +26

We present a set of companion dynamical masses and orbital parameters of seven star systems from the NEID Earth Twin Survey with significant absolute astrometric accelerations betw…

Searching for GEMS: Confirmation of TOI-5573b, a Cool, Saturn-like Planet Orbiting An M-dwarf

Rachel B Fernandes, Shubham Kanodia, Megan Delamer +35

We present the confirmation of TOI-5573b, a Saturn-sized exoplanet on an 8.79-day orbit around an early M-dwarf (3790 K, 0.59 R, 0.61 M, 12.30 J mag). TOI-5573b has a…

Three-dimensional Orbit and Dynamical Masses of GJ 105 AC

Cayla M. Dedrick, Jason T. Wright, Jason D. Eastman +11

The precision of stellar models is higher than the precision at which we are able to measure the masses of most stars, with the notable exception of binaries where we can determine…
