CoRoT 223992193: Investigating the variability in a low-mass, pre-main sequence eclipsing binary with evidence of a circumbinary disk
Edward Gillen, Suzanne Aigrain, Caroline Terquem +10
CoRoT 223992193 is the only known low-mass, pre-main sequence eclipsing binary that shows evidence of a circumbinary disk. The system displays complex photometric and spectroscopic…
The hot Jupiter of the magnetically-active weak-line T Tauri star V830 Tau
J. -F. Donati, L. Yu, C. Moutou +16
We report results of an extended spectropolarimetric and photometric monitoring of the weak-line T Tauri star V830 Tau and its recently-detected newborn close-in giant planet. Our…
CSI 2264: Investigating rotation and its connection with disk accretion in the young open cluster NGC 2264
L. Venuti, J. Bouvier, A. M. Cody +7
The low spin rates measured for solar-type stars at an age of a few Myr (~10% of the break-up velocity) indicate that some mechanism of angular momentum regulation must be at play…
A Model for (Quasi-)Periodic Multi-wavelength Photometric Variability in Young Stellar Objects
Aurora Y. Kesseli, Maya A. Petkova, Kenneth Wood +7
We present radiation transfer models of rotating young stellar objects (YSOs) with hotspots in their atmospheres, inner disk warps and other 3-D effects in the nearby circumstellar…
CSI 2264: Characterizing Young Stars in NGC 2264 with Stochastically Varying Light Curves
John Stauffer, Ann Marie Cody, Luisa Rebull +25
We provide CoRoT and Spitzer light curves, as well as broad-band multi-wavelength photometry and high resolution, multi- and single-epoch spectroscopy for 17 classical T Tauris in…
