The Discovery of K2-232c: Divergent Formation Histories for Hot and Warm Jupiters Based on Outer Companion Eccentricity

Jessica A. Ranshaw, Xian-Yu Wang, Jennifer A. Burt +6

Ever since their discovery, hot Jupiters have been one of the most studied types of exoplanets to exist thanks to their significant size, their proximity to their host star, and th…

The Stellar Observations Network Group (SONG) -- A Legacy Archive of Stellar Time-Domain Spectroscopy

M. N. Lund, F. Grundahl, M. S. Fredslund +41

The Stellar Observations Network Group (SONG) network has operated for more than a decade, providing long-baseline, high-cadence spectroscopic observations of bright stars and the…

Design and Commissioning of an Iodine Cell for the ESPRESSO Spectrograph

Gillian Nave, R. Paul Butler

High resolution echelle spectrographs remain the backbone of precision Doppler radial velocity (RV) programs, detecting almost all known exoplanets within 50 pc. Precision Doppler…

A universal brown dwarf desert formed between planets and stars

Kaiming Cui, Guang-Yao Xiao, Fabo Feng +10

Giant planets and brown dwarfs play a crucial role in star and planet formation, as they are situated at the boundary between planets and stars with uncertain formation mechanisms.…

A Century of Radial Velocity and Astrometric Monitoring of 70 Oph AB: New PFS Data and Constraints on Planetary Companions

Yiting Li, Michael R. Meyer, Skylar D'Angiolillo +29

At a distance of 5.1 pc, the 70 Oph AB binary star system is one of the most favorable targets for future direct imaging and astrometry missions surveying mature, terrestrial plane…

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…

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…

The Super-Puff WASP-193b is On A Well-Aligned Orbit

Samuel W. Yee, Gudmundur Stefansson, Daniel Thorngren +8

The "super-puffs" are a population of planets that have masses comparable to that of Neptune but radii similar to Jupiter, leading to extremely low bulk densities ($ρ_p \lesssim 0.…

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…

Search for Nearby Earth Analogs. III. Detection of ten new planets, three planet candidates, and confirmation of three planets around eleven nearby M dwarfs

Fabo Feng, Stephen A. Shectman, Matthew S. Clement +10

Earth-sized planets in the habitable zones of M dwarfs are good candidates for the study of habitability and detection of biosignatures. To search for these planets, we analyze all…

Detection of Planetary and Stellar Companions to Neighboring Stars via a Combination of Radial Velocity and Direct Imaging Techniques

Stephen R. Kane, Paul A. Dalba, Zhexing Li +13

The sensitivity of radial velocity (RV) surveys for exoplanet detection are extending to increasingly long orbital periods, where companions with periods of several years are now b…

New Constraints on Gliese 876 -- Exemplar of Mean-Motion Resonance

Sarah Millholland, Gregory Laughlin, Johanna Teske +7

Gliese 876 harbors one of the most dynamically rich and well-studied exoplanetary systems. The nearby M4V dwarf hosts four known planets, the outer three of which are trapped in a…

The LCES HIRES/Keck Precision Radial Velocity Exoplanet Survey

R. Paul Butler, Steven S. Vogt, Gregory Laughlin +8

We describe a 20-year survey carried out by the Lick-Carnegie Exoplanet Survey Team (LCES), using precision radial velocities from HIRES on the Keck-I telescope to find and charact…
