Signatures of Strong Magnetization and Metal-Poor Atmosphere for a Neptune-Size Exoplanet
Lotfi Ben-Jaffel, Gilda E. Ballester, Antonio García Muñoz +10
The magnetosphere of an exoplanet has yet to be unambiguously detected. Investigations of star-planet interaction and neutral atomic hydrogen absorption during transit to detect ma…
Exoplanet Radio Transits as a Probe for Exoplanetary Magnetic Fields -- Time-dependent MHD Simulations
Soumitra Hazra, Ofer Cohen, Igor V. Sokolov
We perform a series of time dependent Magnetohydrodynamic simulations of the HD 189733 star-planet system in order to predict radio transit modulations due to the interaction betwe…
Space Weather-driven Variations in Ly Absorption Signatures of Exoplanet Atmospheric Escape: MHD Simulations and the Case of AU Mic b
O. Cohen, J. D. Alvarado-Gomez, J. J. Drake +3
We simulate the space environment around AU Microscopii b and the interaction between the magnetized stellar wind with a planetary atmospheric outflow for ambient stellar wind cond…
Stellar Winds Drive Strong Variations in Exoplanet Evaporative Outflows and Transit Absorption Signatures
Laura M. Harbach, Sofia P. Moschou, Cecilia Garraffo +4
Stellar wind and photon radiation interactions with a planet can cause atmospheric depletion, which may have a potentially catastrophic impact on a planet's habitability. While the…
The HST PanCET Program: An Optical to Infrared Transmission Spectrum of HAT-P-32Ab
Munazza K. Alam, Mercedes Lopez-Morales, Nikolay Nikolov +14
We present a 0.3-5 micron transmission spectrum of the hot Jupiter HAT-P-32Ab observed with the Space Telescope Imaging Spectrograph (STIS) and Wide Field Camera 3 (WFC3) instrumen…
Atmospheric Escape Processes and Planetary Atmospheric Evolution
Guillaume Gronoff, Phil Arras, Suleiman M Baraka +17
The habitability of the surface of any planet is determined by a complex evolution of its interior, surface, and atmosphere. The electromagnetic and particle radiation of stars dri…
