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…
The year-long flux variations in Boyajian's star are asymmetric or aperiodic
Michael Hippke, Daniel Angerhausen
We combine and calibrate publicly available data for Boyajian's star including photometry from ASAS (SN, V, I), Kepler, Gaia, SuperWASP, and citizen scientist observations (AAVSO,…
A first view with GAIA on KIC 8462852 - distance estimates and a comparison to other F stars
Michael Hippke, Daniel Angerhausen
Distance estimates from Gaia parallax and expected luminosities are compared for KIC 8462852. Gaia DR1 yields a parallax of mas, that is a distance of $391.4\substack{…
Sonneberg plate photometry for Boyajian's Star in two passbands
Michael Hippke, Peter Kroll, Frank Matthei +10
The F3 main sequence star KIC 8462852 (Boyajian's Star) showed deep (up to 20%) day-long brightness dips of unknown cause during the 4 years of the Kepler mission. A 0.164 mag (16%…
The Stability of F-star Brightness on Century Timescales
Michael B. Lund, Joshua Pepper, Keivan G. Stassun +2
The century-long photometric record of the DASCH project provides a unique window into the variability of stars normally considered to be photometrically inactive. In this paper, w…
First exoplanet transit observation with the Stratospheric Observatory for Infrared Astronomy: Confirmation of Rayleigh scattering in HD 189733 b with HIPO
Daniel Angerhausen, Georgi Mandushev, Avi Mandell +13
Here we report on the first successful exoplanet transit observation with the Stratospheric Observatory for Infrared Astronomy (SOFIA). We observed a single transit of the hot Jupi…
A comprehensive study of Kepler phase curves and secondary eclipses -- temperatures and albedos of confirmed Kepler giant planets
Daniel Angerhausen, Emily DeLarme, Jon A. Morse
We present a comprehensive study of phase curves and secondary eclipses in the Kepler data set using all data from 16 quarters that were available in 2013-2014. Our sample consists…
