Exomoonlight Sonata: On the Fate of Exomoons Around Migrating White Dwarf Planets
Ritvik Sai Narayan, Joseph R. Livesey, Juliette Becker
The survival of exomoons around close-in white dwarf planets offers a potential constraint on their migration histories and an alternative pathway to post-main-sequence habitabilit…
GJ 523b is a Massive, 170 Myr-old Mega-Earth, Likely on a Polar Orbit
Maxwell A. Kroft, Thomas G. Beatty, Joseph M. Salzer +18
We use WIYN/NEID radial velocity measurements to confirm the planetary nature and measure the mass of the TESS transiting exoplanet candidate around the mid-K dwarf GJ 523 ($V=9.23…
TESS Hunt for Young and Maturing Exoplanets (THYME) XIV: A Comoving-Based Age Constraint for KELT-20
Adam Distler, Melinda Soares-Furtado, Andrew W. Mann +9
Young stellar moving groups offer unique opportunities to investigate the early evolution of stellar and planetary systems. In continuation of an ongoing effort to age-date compell…
THYME XIII: Two young Neptunes orbiting a 75-Myr star in the Alpha Persei Cluster
Anne Dattilo, Andrew M. Vanderburg, Madyson G. Barber +28
Young planets with mass measurements are particularly valuable in studying atmospheric mass-loss processes, but these planets are rare and their masses difficult to measure due to…
Tides Tighten the Hycean Habitable Zone
Joseph R. Livesey, Juliette Becker, Susanna L. Widicus Weaver
Hycean planets -- exoplanets with substantial water ice layers, deep surface oceans, and hydrogen-rich atmospheres -- are thought to be favorable environments for life. Due to a re…
Why M-dwarf flares have limited impact on the atmospheric evaporation of sub-Neptunes and Earth-sized planets
Andrea Caldiroli, Francesco Haardt, Elena Gallo +4
M-type stars are prime targets for exoplanet searches within their habitable zones (HZs). These stars also exhibit significant magnetic flaring activity, particularly during their…
The Effects of Kinematic MHD on the Atmospheric Circulation of Eccentric Hot Jupiters
Hayley Beltz, Willow Houck, Laura C. Mayorga +3
Hot Jupiters are typically considered to be tidally locked due to their short orbital periods. The extreme irradiation can result in atmospheric species becoming thermally ionized…
A Pair of Dynamically Interacting Sub-Neptunes Around TOI-6054
Maxwell A. Kroft, Thomas G. Beatty, Ian J. M. Crossfield +31
We confirm the planetary nature of a pair of transiting sub-Neptune exoplanets orbiting the bright F-type sub-giant star TOI-6054 (, ) as a part of the OrCAS radia…
Secular Perturbations from Exterior Giants Strongly Influence Gap Complexity in Peas-in-a-Pod Exoplanetary Systems
Joseph R. Livesey, Juliette Becker
It has been demonstrated that systems of tightly packed inner planets with giant exterior companions tend to have less regular orbital spacings than those without such companions.…
