HIP 61637 b: a TESS Brown Dwarf in a Near-circular Orbit around a Massive A-type Star
Nino Ephremidze, David W. Latham, Perry Berlind +8
We present the characterization of HIP 61637 b (TOI-5401 b), a brown dwarf discovered by TESS to transit an A-type star. HIP 61637 is the most massive and the brightest star known…
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…
TOI-7169 b: A Hot Jupiter Transiting a Metal-Poor Star
Joshua D. Simon, Joseph E. Rodriguez, Jhon Yana Galarza +38
Most known planets are found around metal-rich host stars, which has made it difficult to determine whether a lower metallicity limit for planet formation exists and how the proper…
TOI-2155 b: A Massive Brown Dwarf or a Very Low-Mass Star?
Md Redyan Ahmed, Tansu Daylan, Theron W. Carmichael +14
We present TOI-2155\,b, a massive transiting companion, discovered using data from NASA's Transiting Exoplanet Survey Satellite (TESS) mission and confirmed with ground-based RV me…
High five from ASTEP: Three validated planets and two eclipsing binaries in a diverse set of long-period candidates
Erika Rea, Maximilian N. Günther, George Dransfield +44
We present the analysis of five long-period TESS Objects of Interest (TOIs), all orbiting Sun-like stars, with orbital periods exceeding one month. Initially identified by the Tran…
A Planetary Illusion's Funeral: Non-detection of a Gaia DR3 Exoplanet Candidate, and the Role of Intermediate-precision Radial Velocities in Gaia Exoplanet Follow-up
Alexander Venner, Chelsea X. Huang, David W. Latham +4
The detection of exoplanets using astrometry has long been an area of interest, but is fraught with challenges. The Gaia mission is fundamentally reshaping this field thanks to its…
