TESS discovery of two super-Earths orbiting the M-dwarf stars TOI-6002 and TOI-5713 near the radius valley
M. Ghachoui, B. V. Rackham, M. Dévora-Pajares +45
We present the validation of two TESS super-Earth candidates transiting the mid-M dwarfs TOI-6002 and TOI-5713 every 10.90 and 10.44 days, respectively. The first star (TOI-6002) i…
Discovery and characterization of a dense sub-Saturn TOI-6651b
Sanjay Baliwal, Rishikesh Sharma, Abhijit Chakraborty +13
We report the discovery and characterization of a transiting sub-Saturn exoplanet TOI-6651b using PARAS-2 spectroscopic observations. The host, TOI-6651 (), is a…
Mass determination of two Jupiter-sized planets orbiting slightly evolved stars: TOI-2420 b and TOI-2485 b
Ilaria Carleo, Oscar Barrágan, Carina M. Persson +67
Hot and warm Jupiters might have undergone the same formation and evolution path, but the two populations exhibit different distributions of orbital parameters, challenging our und…
Trials and Tribulations in the Reanalysis of KELT-24 b: a Case Study for the Importance of Stellar Modeling
Mark R. Giovinazzi, Bryson Cale, Jason D. Eastman +21
We present a new analysis of the KELT-24 system, comprising a well-aligned hot Jupiter, KELT-24~b, and a bright (), nearby () F-type host star. KELT-24~b…
Using JWST transits and occultations to determine stellar radii and temperatures of low-mass stars
Alexandra S. Mahajan, Jason D. Eastman, James Kirk
Using JWST observations of a primary transit and two secondary eclipses for GJ 1214b, we determine an eccentricity that is more precise than a decade of HARPS data, which enables u…
The TESS-Keck Survey. XIX. A Warm Transiting Sub-Saturn Mass Planet and a non-Transiting Saturn Mass Planet Orbiting a Solar Analog
Michelle L. Hill, Stephen R. Kane, Paul A. Dalba +45
The Transiting Exoplanet Survey Satellite (TESS) continues to dramatically increase the number of known transiting exoplanets, and is optimal for monitoring bright stars amenable t…
