Hd 209458: physical parameters of the parent star and the transiting planet
The Sun-like star HD 209458 harbors a close-in giant planet that transits across the star's disk, and thus allows an unprecedented access to the basic parameters of the planet, given a certain
Rotation in the Pleiades with K2: I. Data and First Results
Young (125 Myr), populous ($>$1000 members), and relatively nearby, the Pleiades has provided an anchor for stellar angular momentum models for both younger and older stars. We used K2 to explore the
Rotation of Low-mass Stars in Upper Scorpius and ρ Ophiuchus with K2
We present an analysis of K2 light curves (LCs) for candidate members of the young Upper Sco (USco) association (~8 Myr) and the neighboring ρ Oph embedded cluster (~1 Myr). We establish ~1300 stars
CSI 2264: Simultaneous optical and infrared light curves of young disk-bearing stars in NGC 2264 with CoRoT and Spitzer-- evidence for multiple origins of variability
We present the Coordinated Synoptic Investigation of NGC 2264, a continuous 30 day multi-wavelength photometric monitoring campaign on more than 1000 young cluster members using 16 telescopes. The
Mapping accretion and its variability in the young open cluster NGC 2264: a study based on u-band photometry
Context. The accretion process has a central role in the formation of stars and planets. Aims. We aim at characterizing the accretion properties of several hundred members of the star-forming
New Pleiades Eclipsing Binaries and a Hyades Transiting System Identified by K2
We present the discovery in Kepler's $K2$ mission observations and our follow-up radial velocity observations from Keck/HIRES for four eclipsing binary (EB) star systems in the young benchmark
A Neptune-sized transiting planet closely orbiting a 5–10-million-year-old star
A newly born, transiting planet orbiting its star with a period of 5.4 days is reported, which is 50 per cent larger than Neptune, and its mass is less than 3.6 times that of Jupiter, with a true mass likely to be similar to that of Neptune.
Precision Photometric Monitoring of Very Low Mass σ Orionis Cluster Members: Variability and Rotation at a Few Myr
We present high-precision photometry on 107 variable low-mass stars and brown dwarfs in the ~3 Myr σ Orionis open cluster. We have carried out I-band photometric monitoring within two fields,
K2 Rotation Periods for low-mass Hyads and the Implications for Gyrochronology
As the closest open cluster to the Sun, the Hyades is an important benchmark for many stellar properties, but its members are also scattered widely over the sky. Previous studies of stellar rotation
