Gaia astrometry disfavors a binary origin for long secondary periods
Cheyanne Shariat, Kareem El-Badry, Morgan MacLeod +1
Approximately one-third of luminous pulsating red giant stars exhibit long secondary periods (LSPs): stable photometric variability with periods of several months to years in addit…
Enhancement of the Rate of Tidal Disruption Events in Active Galactic Nuclei due to the Sweeping Secular Resonance Mechanism
Xiaochen Zheng, Morgan MacLeod, Douglas N. C. Lin +2
Tidal disruption event (TDE) rates in active galactic nuclei (AGN) consistently exceed predictions from two-body relaxation, particularly in post-starburst and green valley galaxie…
Streams and Bubbles: Tidal Shaping of Planetary Outflows
Morgan MacLeod, Antonija Oklopčić, Fabienne Nail +1
Planets lose mass to atmospheric outflows, and this mass loss is thought to be central in shaping the bimodal population of gaseous giant and rocky terrestrial exoplanets in close…
sunset: A database of synthetic atmospheric-escape transmission spectra for nearly every transiting planet
Dion Linssen, Antonija Oklopčić, Morgan MacLeod
Studying atmospheric escape from exoplanets can provide important clues about the formation and evolution of exoplanets. Observational evidence of atmospheric escape has been obtai…
Cold day-side winds shape large leading streams in evaporating exoplanet atmospheres
F. Nail, M. MacLeod, A. Oklopčić +3
Recent observations of planetary atmospheres in HAT-P-32 b and HAT-P-67 b reveal extensive outflows reaching up to hundreds of planetary radii. The helium 1083 nm light curves for…
The open-source sunbather code: modeling escaping planetary atmospheres and their transit spectra
Dion Linssen, Jim Shih, Morgan MacLeod +1
Atmospheric escape is thought to significantly influence the evolution of exoplanets, especially for sub-Jupiter planets on short orbital periods. Theoretical models predict that h…
Helium in the Extended Atmosphere of the Warm Super-Puff TOI-1420b
Shreyas Vissapragada, Michael Greklek-McKeon, Dion Linssen +11
Super-puffs are planets with exceptionally low densities (~g~cm) and core masses (). Many lower-mass () super-…
Effects of planetary day-night temperature gradients on He 1083 nm transit spectra
Fabienne Nail, Antonija Oklopčić, Morgan MacLeod
A notable fraction of helium observations probing the evaporating atmospheres of short-period gas giants at 1083~nm exhibit a blueshift during transit, which might be indicative of…
