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…
Kepler-21b: A rocky planet around a V = 8.25 magnitude star
Mercedes Lopez-Morales, Raphaelle D. Haywood, Jeffrey L. Coughlin +36
HD 179070, aka Kepler-21, is a V = 8.25 F6IV star and the brightest exoplanet host discovered by Kepler. An early detailed analysis by Howell et al. (2012) of the first thirteen mo…
A 1.9 Earth radius rocky planet and the discovery of a non-transiting planet in the Kepler-20 system
Lars A. Buchhave, Courtney D. Dressing, Xavier Dumusque +35
Kepler-20 is a solar-type star (V = 12.5) hosting a compact system of five transiting planets, all packed within the orbital distance of Mercury in our own Solar System. A transiti…
Uncovering the planets and stellar activity of CoRoT-7 using only radial velocities
J. P. Faria, R. D. Haywood, B. J. Brewer +4
Stellar activity can induce signals in the radial velocities of stars, complicating the detection of orbiting low-mass planets. We present a method to determine the number of plane…
The Sun as a planet-host star: Proxies from SDO images for HARPS radial-velocity variations
R. D. Haywood, A. Collier Cameron, Y. C. Unruh +11
The Sun is the only star whose surface can be directly resolved at high resolution, and therefore constitutes an excellent test case to explore the physical origin of stellar radia…
Long-term radial-velocity variations of the Sun as a star: The HARPS view
A. F. Lanza, P. Molaro, L. Monaco +1
Stellar radial velocities play a fundamental role in the discovery of extrasolar planets and the measurement of their physical parameters as well as in the study of stellar physica…
