TOI-6884b: A low-mass brown dwarf transiting a slightly evolved star
Akanksha Khandelwal, Shubhendra Nath Das, Rishikesh Sharma +42
We report the discovery of a low-mass transiting brown dwarf orbiting TOI-6884 (TIC~156514476, ) from NASA's \textit{Transiting Exoplanet Survey Satellite} (\text…
A Uniform Determination of the Bulk Metallicities and Alpha Enrichments of Confirmed Exoplanet Systems with TRES
Romy RodrÃguez MartÃnez, Emily K. Pass, Phillip A. Cargile +4
We present a uniform spectroscopic characterization of 625 F, G, and K stars hosting 859 confirmed exoplanets using high-resolution archival optical spectra from the Tillinghast Re…
TOI-6692b: An eccentric 130 day period giant planet with a single transit from TESS
Allyson Bieryla, Karen A. Collins, George Zhou +46
We report the discovery and characterization of TOI-6692 b, an eccentric (e~0.54) Jupiter on a 130-day orbit. TOI-6692 b was first detected as a community TESS Object of Interest (…
A Paradigm Shift in Exoplanet False Positive Identification with HIP-44302
Arielle C. Frommer, Jason D. Eastman, David R. Ciardi +5
Through detailed modeling of all three stars, we show that HIP-44302 is a false positive triple-star system. While the Transiting Exoplanet Survey Satellite initially designated th…
Migration and Evolution of giant ExoPlanets (MEEP) II: Super-Jupiters and Lithium-rich Host Stars
Jack Schulte, Joseph E. Rodriguez, David W. Latham +30
Although hot Jupiters were the first exoplanets discovered orbiting main sequence stars, the dominant mechanisms through which they form and evolve are not known. To address the qu…
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…
