TL;DR
This paper presents a comprehensive analysis of TESS exoplanet candidates using radial velocity data from the TESS-Keck Survey, resulting in new planet mass measurements, validations, and a valuable data release, advancing exoplanet characterization.
Contribution
It provides a uniform RV analysis of all TESS-Keck Survey targets, including mass constraints for 126 planets, validation of 32 new planets, and a large data release, improving exoplanet characterization methods.
Findings
Mass constraints for 126 planets, including 58 with high-precision measurements.
Validation of 32 new planets from TESS data.
Assessment of survey performance and comparison with mass-radius relations.
Abstract
The Transiting Exoplanet Survey Satellite (TESS) has discovered hundreds of new worlds, with TESS planet candidates now outnumbering the total number of confirmed planets from . Owing to differences in survey design, TESS continues to provide planets that are better suited for subsequent follow-up studies, including mass measurement through radial velocity (RV) observations, compared to Kepler targets. In this work, we present the TESS-Keck Survey's (TKS) Mass Catalog: a uniform analysis of all TKS RV survey data which has resulted in mass constraints for 126 planets and candidate signals. This includes 58 mass measurements that have reached precision. We confirm or validate 32 new planets from the TESS mission either by significant mass measurement (15) or statistical validation (17), and we find no evidence of likely false positives among our entire…
