Evidence for an Extended Hydrogen Outflow on WASP-12 b
Morgan Saidel, Shreyas Vissapragada, Heather A. Knutson +6
Recent observations of atmospheric escape from planets orbiting early-type stars indicate that planets with higher Roche filling factors have significantly higher mass loss rates.…
WASP-12b Exhibits Persistent In-Transit H Absorption
Shreyas Vissapragada, Fabienne Nail, Morgan MacLeod +6
High-resolution H and He 10830 Å transit spectroscopy can trace the extended upper atmospheres of exoplanets, typically revealing excess in-transit absorption that occurs in the…
Time-resolved rotational velocities in the upper atmosphere of WASP-33 b
P. Wilson Cauley, Ji Wang, Evgenya L. Shkolnik +4
While steady empirical progress has been made in understanding the structure and composition of hot planet atmospheres, direct measurements of velocity signatures, including winds,…
No consistent atmospheric absorption detected for the ultra-hot Jupiter WASP-189 b
P. Wilson Cauley, Evgenya Shkolnik, Ilya Ilyin +3
We observed a partial transit of the ultra-hot Jupiter WASP-189 b with PEPSI on the LBT. We detect a highly variable transit signal in multiple atomic transitions, including H-alph…
Reconstructing Extreme Space Weather from Planet Hosting Stars
V. S. Airapetian, V. Adibekyan, M. Ansdell +80
The field of exoplanetary science is making rapid progress both in statistical studies of exoplanet properties as well as in individual characterization. As space missions provide…
Atmospheric dynamics and the variable transit of KELT-9 b
P. Wilson Cauley, Evgenya L. Shkolnik, Ilya Ilyin +3
We present a spectrally and temporally resolved detection of the optical Mg I triplet at 7.8 in the extended atmosphere of the ultra-hot Jupiter KELT-9 b, adding to the list of…
