HD 715 b, a Warm Jupiter Orbiting a Massive Subgiant Discovered from a Single TESS Transit

Alexander Venner, Robert A. Wittenmyer, Andrew Vanderburg +23

Transiting Warm Jupiters orbiting bright stars are scarcely known, but a substantial number of these planets have been uncovered by the TESS mission. In this work we report the dis…

TOI-3664 b, TOI-4034 b & TOI-6564 b: Three new hot Jupiters around stars approaching the terminal age main sequence

Matthew P. Battley, Marina Lafarga, Edward Gillen +21

Studying the evolution of hot Jupiters requires a sample of well-characterised systems across all evolutionary states. We present three new gas giant exoplanets around stars approa…

JWST unveils a high mean molecular weight atmosphere for mini-Neptune TOI-1130b: Evidence for formation beyond the water ice line

Saugata Barat, Tyler Fairnington, Shelby Courreges +21

We present the combined JWST/NIRSpec G395H and NIRISS SOSS transmission spectrum of a warm mini-Neptune, TOI-1130b (3.66 R, 19.8 M, K). It is…

Exploring Warm Jupiter Migration Pathways with Eccentricities. I. Catalog of Uniform Keplerian Fits to Radial Velocities of 200 Warm Jupiters

Marvin Morgan, Brendan P. Bowler, Quang H. Tran +4

Giant planets are expected to predominantly form beyond the water ice line and occasionally undergo inward migration. Unlike hot Jupiters, which can result from high-eccentricity t…

The Spin-orbit alignment of two short period eclipsing binary systems

Tony Wells, B. C. Addison, R. A. Wittenmyer +8

We present a joint analysis of TESS photometry and radial velocity measurements obtained from the Minerva-Australis facility for two short-period eclipsing binaries, TIC 48227288 a…

Searching for helium escape and a low density atmosphere around the 120 Myr old sub-Neptune HIP94235b using CRIRES+

Ava Morrissey, George Zhou, Chelsea X. Huang +6

Atmospheric mass loss is thought to induce the bimodality in the small planet population as we observe it today. Observationally, active mass loss can be traced by excess absorptio…

The Eccentricity Distribution of Warm Sub-Saturns in TESS

Tyler R. Fairnington, Jiayin Dong, Chelsea X. Huang +45

We present the eccentricity distribution of warm sub-Saturns (4-8 Re, 8-200 day periods) as derived from an analysis of transit light curves from NASA's Transiting Exoplanet Survey…

A 16 Myr super-Neptune in Upper-Centaurus Lupus and a preliminary survey of transiting planets in Sco-Cen with TESS

Sydney Vach, George Zhou, Andrew W. Mann +25

Measuring the properties of planets younger than about 50 Myr helps to test different planetary formation and evolution models. NASA's Transiting Exoplanet Survey Satellite (TESS)…

A catalog of binary stars from phase modulation in the first four years of TESS Mission photometry

Shishir Dholakia, Simon J. Murphy, Chelsea X. Huang +2

We present a catalog of binary companions to Scuti stars, detected through phase modulations of their pulsations in TESS data. Pulsation timing has provided orbits for hundreds…

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…

Searching for Neutral Hydrogen Escape from the 120 Myr Old Sub-Neptune HIP94235b using HST

Ava Morrissey, George Zhou, Chelsea X. Huang +9

HIP94235 b, a 120 Myr old sub-Neptune, provides us the unique opportunity to study mass loss at a pivotal stage of the system's evolution: the end of a 100 million year (Myr) old p…

Surviving in the Hot Neptune Desert: The Discovery of the Ultra-Hot Neptune TOI-3261b

Emma Nabbie, Chelsea X. Huang, Jennifer A. Burt +45

The recent discoveries of Neptune-sized ultra-short period planets (USPs) challenge existing planet formation theories. It is unclear whether these residents of the Hot Neptune Des…

HD 21520 b: a warm sub-Neptune transiting a bright G dwarf

Molly Nies, Ismael Mireles, François Bouchy +49

We report the discovery and validation of HD 21520 b, a transiting planet found with TESS and orbiting a bright G dwarf (V=9.2, K, $R_{\star} = 1.04\pm 0.02…

Gliese 12 b, A Temperate Earth-sized Planet at 12 Parsecs Discovered with TESS and CHEOPS

Shishir Dholakia, Larissa Palethorpe, Alexander Venner +33

We report on the discovery of Gliese 12 b, the nearest transiting temperate, Earth-sized planet found to date. Gliese 12 is a bright ( mag, mag) metal-poor M4V star…

TOI-5126: A hot super-Neptune and warm Neptune pair discovered by and

Tyler R. Fairnington, Emma Nabbie, Chelsea X. Huang +33

We present the confirmation of a hot super-Neptune with an exterior Neptune companion orbiting a bright (V = 10.1 mag) F-dwarf identified by the $\textit{Transiting Exoplanet Surve…

Planets around young active Solar-type stars: Assessing detection capabilities from a non stabilised spectrograph

A. Heitzmann, S. C. Marsden, P. Petit +8

Short-orbit gas giant planet formation/evolution mechanisms are still not well understood. One promising pathway to discriminate between mechanisms is to constrain the occurrence r…

KELT-25b and KELT-26b: A Hot Jupiter and a Substellar Companion Transiting Young A-stars Observed by TESS

Romy Rodríguez Martínez, B. Scott Gaudi, Joseph E. Rodriguez +89

We present the discoveries of KELT-25b (TIC 65412605, TOI-626.01) and KELT-26b (TIC 160708862, TOI-1337.01), two transiting companions orbiting relatively bright, early A-stars. Th…
