Sarah Ballard, Jessie L. Christiansen, David Charbonneau +14
We present time series photometry of the M dwarf transiting exoplanet system GJ 436 obtained with the the EPOCh (Extrasolar Planet Observation and Characterization) component of th…
Exoplanetary Spin-Orbit Alignment: Results from the Ensemble of Rossiter-McLaughlin Observations
Daniel C. Fabrycky, Joshua N. Winn
One possible diagnostic of planet formation, orbital migration, and tidal evolution is the angle psi between a planet's orbital axis and the spin axis of its parent star. In genera…
On the Spin-Orbit Misalignment of the XO-3 Exoplanetary System
Joshua N. Winn, John Asher Johnson, Daniel Fabrycky +8
We present photometric and spectroscopic observations of the 2009 Feb. 2 transit of the exoplanet XO-3b. The new data show that the planetary orbital axis and stellar rotation axis…
On the triple origin of blue stragglers
Hagai B. Perets, Daniel C. Fabrycky
Blue straggler stars (BSSs) are stars observed to be hotter and bluer than other stars with the same luminosity in their environment. As such they appear to be much younger than th…
