The Pandora SmallSat: post-launch operations and mission update
Trevor O. Foote, Elisa V. Quintana, Jessie L. Dotson +41
The Pandora SmallSat is a NASA flight project designed to study the atmospheres of exoplanets. Transmission spectroscopy of transiting exoplanets provides our best opportunity to i…
The NEID Earth Twin Survey. VI. Discovery of a Low-Mass Planet Orbiting HD 126053 and RV Signals Near the Rotation Periods of HD 168009 and HD 10780
Arvind F. Gupta, Sarah E. Logsdon, Jacob K. Luhn +19
Extreme precision radial velocity (EPRV) spectrographs are making strides in extending the limits of radial velocity exoplanet detection. Perhaps the best evidence for this is how…
A Revised Mass and Period for the Habitable Zone super-Earth GJ 3378b: A Planet Straddling the Cosmic Shoreline
Paul Robertson, Michael Endl, William D. Cochran +18
The nearby ( pc) M4V star GJ~3378 is a target of our radial velocity (RV) exoplanet survey of fully convective stars in the Solar neighborhood with the near-infrared spect…
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)…
The NEID Earth Twin Survey. IV. Confirming an 89 d, Planet Orbiting a Nearby Sun-like Star
Mark R. Giovinazzi, Evan Fitzmaurice, Arvind F. Gupta +19
We present the confirmation of HD 190360 d, a warm (), low-mass () planet orbiting the nearb…
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…
The TESS Grand Unified Hot Jupiter Survey. III. Thirty More Giant Planets
Samuel W. Yee, Joshua N. Winn, Joel D. Hartman +123
We present the discovery of 30 transiting giant planets that were initially detected using data from NASA's Transiting Exoplanet Survey Satellite (TESS) mission. These new planets…
Time-resolved p-mode oscillations for subgiant HD 142091 with NEID at WIYN
Jacob K. Luhn, Paul Robertson, Samuel Halverson +22
Detections of Earth-analog planets in radial velocity observations are limited by stellar astrophysical variability occurring on a variety of timescales. Current state-of-the-art m…
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…
Jitter Across 15 Years: Leveraging Precise Photometry from Kepler and TESS to Extract Exoplanets from Radial Velocity Time Series
Corey Beard, Paul Robertson, Jack Lubin +24
Stellar activity contamination of radial velocity (RV) data is one of the top challenges plaguing the field of extreme precision RV (EPRV) science. Previous work has shown that pho…
The Immediate, Exemplary, and Fleeting echelle spectroscopy of SN 2023ixf: Monitoring acceleration of slow progenitor circumstellar material, driven by shock interaction
