The Random Transiter -- EPIC 249706694/HD 139139
S. Rappaport, A. Vanderburg, M. H. Kristiansen +16
We have identified a star, EPIC 249706694 (HD 139139), that was observed during K2 Campaign 15 with the Kepler extended mission that appears to exhibit 28 transit-like events over…
High-Resolution Spectroscopic Detection of TiO and Stratosphere in the Day-side of WASP-33b
Stevanus K. Nugroho, Hajime Kawahara, Kento Masuda +3
We report high-resolution spectroscopic detection of TiO molecular signature in the day-side spectra of WASP-33 b, the second hottest known hot Jupiter. We used High-Dispersion Spe…
Eccentric Companions to Kepler-448b and Kepler-693b: Clues to the Formation of Warm Jupiters
Kento Masuda
I report the discovery of non-transiting close companions to two transiting warm Jupiters (WJs), Kepler-448/KOI-12b (orbital period , radius $R_{\rm p}=1.23^…
Transiting Planet Candidates Beyond the Snow Line Detected by Visual Inspection of 7557 Kepler Objects of Interest
Sho Uehara, Hajime Kawahara, Kento Masuda +2
We visually inspected the light curves of 7557 Kepler Objects of Interest (KOIs) to search for single transit events (STEs) possibly due to long-period giant planets. We identified…
Spin-Orbit Angles of Kepler-13Ab and HAT-P-7b from Gravity-Darkened Transit Light Curves
Kento Masuda
Analysis of the transit light curve deformed by the stellar gravity darkening allows us to photometrically measure both components of the spin-orbit angle , its sky projection $…
