Probing the extent of WASP-52 b's atmosphere. High-resolution observations and 3D modeling insights
F. Nail, A. OklopÄiÄ, M. MacLeod +5
WASP-52 b is an inflated hot Jupiter with a large Roche lobe filling fraction, positioned in the hot Neptune desert. Previous in-transit observations of the helium triplet at 10833…
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…
Cold day-side winds shape large leading streams in evaporating exoplanet atmospheres
F. Nail, M. MacLeod, A. OklopÄiÄ +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…
Streams and Bubbles: Tidal Shaping of Planetary Outflows
Morgan MacLeod, Antonija OklopÄiÄ, 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…
