Hot Stars With Kepler Planets Have High Obliquities
Emma M. Louden, Joshua N. Winn, Erik A. Petigura +5
It has been known for a decade that hot stars with hot Jupiters tend to have high obliquities. Less is known about the degree of spin-orbit alignment for hot stars with other kinds…
Dippers from the TESS Full-Frame Images I: The Results of the first 1 year data and Discovery of A Runaway dipper
Tomoyuki Tajiri, Hajime Kawahara, Masataka Aizawa +9
We present a comprehensive catalog of the dippers---young stellar objects that exhibit episodic dimming---derived from the one year's worth of data of Transiting Exoplanet Survey S…
Revisiting the Architecture of the KOI-89 System
Kento Masuda, Daniel Tamayo
While high stellar obliquities observed in exoplanetary systems may be attributed to processes that tilt the planetary orbits, it is also possible that they reflect misalignments b…
Bayesian Dynamic Mapping of an Exo-Earth from Photometric Variability
Hajime Kawahara, Kento Masuda
Photometric variability of a directly imaged exo-Earth conveys spatial information on its surface and can be used to retrieve a two-dimensional geography and axial tilt of the plan…
On the Inference of a Star's Inclination Angle from its Rotation Velocity and Projected Rotation Velocity
Kento Masuda, Joshua N. Winn
It is possible to learn about the orientation of a star's rotation axis by combining measurements of the star's rotation velocity () and its projection onto our line of sight ($…
Four New Self-lensing Binaries from Kepler: Radial Velocity Characterization and Astrophysical Implications
Kento Masuda, Hajime Kawahara, David W. Latham +5
In Kawahara et al. (2018) and Masuda et al. (2019), we reported the discovery of four self-lensing binaries consisting of F/G-type stars and (most likely) white dwarfs whose masses…
