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…
Evidence of magnetic star-planet interactions in the HD 189733 system from orbitally-phased Ca II K variations
P. Wilson Cauley, Evgenya L. Shkolnik, Joe Llama +2
Magnetic star-planet interactions (SPI) provide a detection method and insight into exoplanet magnetic fields and, in turn, exoplanet interiors and atmospheric environments. These…
K2-140b and K2-180b - Characterization of a hot Jupiter and a mini-Neptune from the K2 mission
J. Korth, Sz. Csizmadia, D. Gandolfi +40
We report the independent discovery and characterization of two K2 planets: K2-180b, a mini-Neptune-size planet in an 8.9-day orbit transiting a V = 12.6 mag, metal-poor ([Fe/H] =$…
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…
Black hole remnants may exist if Starobinsky inflation occurred
Paul R. Anderson, Mathew J. Binkley, Jillian M. Bjerke +1
Zero temperature black hole solutions to the semiclassical backreaction equations are investigated. Evidence is provided that certain components of the stress-energy tensors for fr…
Dust Production and Depletion in Evolved Planetary Systems
J. Farihi, R. van Lieshout, P. W. Cauley +15
The infrared dust emission from the white dwarf GD 56 is found to rise and fall by 20% peak-to-peak over 11.2 yr, and is consistent with ongoing dust production and depletion. It i…
