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…
Interpretation and diversity of exoplanetary material orbiting white dwarfs
Andrew Swan, Jay Farihi, Detlev Koester +5
Nine metal-polluted white dwarfs are observed with medium-resolution optical spectroscopy,where photospheric abundances are determined and interpreted through comparison against so…
Magnetic field strengths of hot Jupiters from signals of star-planet interactions
P. Wilson Cauley, Evgenya L. Shkolnik, Joe Llama +1
Evidence of star-planet interactions in the form of planet-modulated chromospheric emission has been noted for a number of hot Jupiters. Magnetic star-planet interactions involve t…
High-Energy Photon and Particle Effects onExoplanet Atmospheres and Habitability
Jeremy J. Drake, Julián D. Alvarado-Gómez, Vladimir Airapetian +41
It is now recognized that energetic stellar photon and particle radiation evaporates and erodes planetary atmospheres and controls upper atmospheric chemistry. Key exoplanet host s…
Constraining Stellar Photospheres as an Essential Step for Transmission Spectroscopy of Small Exoplanets
Benjamin V. Rackham, Arazi Pinhas, Dániel Apai +29
Transmission spectra probe the atmospheres of transiting exoplanets, but these observations are also subject to signals introduced by magnetic active regions on host stars. Here we…
Multi-wavelength observations of the EUV variable metal-rich white dwarf GD 394
David J. Wilson, Boris T. Gaensicke, Detlev Koester +13
We present new Hubble Space Telescope (HST) ultraviolet and ground-based optical observations of the hot, metal-rich white dwarf GD 394. Extreme-ultraviolet (EUV) observations in 1…
