Dynamical Tides during High-Eccentricity Migration produces the Hot Jupiter Pile-up, Neptune Ridge, and Neptune Desert
J. J. Zanazzi, Morgan MacLeod, Marta L. Bryan +1
The period distribution of hot gaseous exoplanets depends strongly on mass. Clustering between the orbital periods of 3 to 5-6 days is seen for sub-Saturns ("Neptune ri…
The First Dedicated Survey of Atmospheric Escape from Planets Orbiting F Stars
Morgan Saidel, Shreyas Vissapragada, Heather Knutson +9
Hydrodynamic escape can strip the envelopes of close-in exoplanets, but most observations of atmospheric mass loss to date have been confined to planets orbiting K and M dwarfs. A…
VIPER: A high-resolution multimode fiber-fed VIPA spectrograph concept for characterizing exoplanet atmospheric escape
Matthew C. H. Leung, David Charbonneau, Andrew Szentgyorgyi +7
An increasing number of applications in exoplanetary science require spectrographs with high resolution and high throughput without the need for a broad spectral range. Examples in…
Modeling tails of escaping gas in exoplanet atmospheres with Harmonica
Carlos Gascón, Mercedes López-Morales, Shreyas Vissapragada +5
Exoplanets that reside close to their host stars, and therefore receive substantial amounts of X-ray and ultraviolet radiation, are prone to suffer from strong atmospheric escape.…
