Orbital misalignment of the Neptune-mass exoplanet GJ 436b with the spin of its cool star
Vincent Bourrier, Christophe Lovis, Hervé Beust +12
The angle between the spin of a star and its planets' orbital planes traces the history of the planetary system. Exoplanets orbiting close to cool stars are expected to be on circu…
Hubble PanCET: An isothermal day-side atmosphere for the bloated gas-giant HAT-P-32Ab
N. Nikolov, D. K. Sing, J. Goyal +20
We present a thermal emission spectrum of the bloated hot Jupiter HAT-P-32Ab from a single eclipse observation made in spatial scan mode with the Wide Field Camera 3 (WFC3) aboard…
The discovery and mass measurement of a new ultra-short-period planet: EPIC~228732031b
Fei Dai, Joshua N. Winn, Davide Gandolfi +51
We report the discovery of a new ultra-short-period planet and summarize the properties of all such planets for which the mass and radius have been measured. The new planet, EPIC~2…
Contemporaneous Imaging Comparisons of the Spotted Giant Geminorum Using Interferometric, Spectroscopic, and Photometric Data
Rachael M. Roettenbacher, John D. Monnier, Heidi Korhonen +8
Nearby, active stars with relatively rapid rotation and large starspot structures offer the opportunity to compare interferometric, spectroscopic, and photometric imaging technique…
The quadruple-lined, doubly-eclipsing system V482 Persei
Guillermo Torres, Claud H. Sandberg Lacy, Francis C. Fekel +2
We report spectroscopic and differential photometric observations of the A-type system V482 Per that reveal it to be a rare hierarchical quadruple system containing two eclipsing b…
An ultrahot gas-giant exoplanet with a stratosphere
Thomas M. Evans, David K. Sing, Tiffany Kataria +24
Infrared radiation emitted from a planet contains information about the chemical composition and vertical temperature profile of its atmosphere. If upper layers are cooler than low…
