Removal of Hot Saturns in Mass-Radius Plane by Runaway Mass Loss
Daniel P. Thorngren, Eve J. Lee, Eric D. Lopez
The hot Saturn population exhibits a boundary in mass-radius space, such that no planets are observed at a density less than 0.1 g cm. Yet, planet interior structure m…

Short-period sub-Neptunes with substantial volatile envelopes are among the most common type of known exoplanets. However, recent studies of the Kepler population have suggested a…
Slow Cooling and Fast Reinflation for Hot Jupiters
Daniel P. Thorngren, Jonathan J. Fortney, Eric D. Lopez +2
The unexpectedly large radii of hot Jupiters are a longstanding mystery whose solution will provide important insights into their interior physics. Many potential solutions have be…
An Ultra-Hot Neptune in the Neptune desert
James S. Jenkins, Matías R. Díaz, Nicolás T. Kurtovic +81
About one out of 200 Sun-like stars has a planet with an orbital period shorter than one day: an ultra-short-period planet (Sanchis-ojeda et al. 2014; Winn et al. 2018). All of the…
TOI-824 b: A New Planet on the Lower Edge of the Hot Neptune Desert
Jennifer A. Burt, Louise D. Nielsen, Samuel N. Quinn +54
We report the detection of a transiting hot Neptune exoplanet orbiting TOI-824 (SCR J1448-5735), a nearby (d = 64 pc) K4V star, using data from the \textit{Transiting Exoplanet Sur…
TOI-1235 b: a keystone super-Earth for testing radius valley emergence models around early M dwarfs
Ryan Cloutier, Joseph E. Rodriguez, Jonathan Irwin +85
Small planets on close-in orbits tend to exhibit envelope mass fractions of either effectively zero or up to a few percent depending on their size and orbital period. Models of the…
An Unusual Transmission Spectrum for the Sub-Saturn KELT-11b Suggestive of a Sub-Solar Water Abundance
Knicole D. Colón, Laura Kreidberg, Luis Welbanks +30
We present an optical-to-infrared transmission spectrum of the inflated sub-Saturn KELT-11b measured with the Transiting Exoplanet Survey Satellite (TESS), the Hubble Space Telesco…
Toward Complete Characterization: Prospects for Directly Imaging Transiting Exoplanets
Christopher C. Stark, Courtney Dressing, Shannon Dulz +4
High contrast direct imaging of exoplanets can provide many important observables, including measurements of the orbit, spectra that probe the lower layers of the atmosphere, and p…
Re-inflation of warm and hot Jupiters
Thaddeus D. Komacek, Daniel P. Thorngren, Eric D. Lopez +1
Understanding the anomalous radii of many transiting hot gas giant planets is a fundamental problem of planetary science. Recent detections of re-inflated warm Jupiters orbiting po…
