CoRoT-18 b: Analysis of high-precision transit light curves with starspot features
St. Raetz, A. M. Heras, P. Gondoin +4
When a planet occults a spotty area on a stellar surface, the flux increases and a characteristic feature in a light curve - a bump - is observed. Among the planets detected by the…
Multi-wavelength variability of the young solar analog iota Hor. X-ray cycle, star spots, flares, and UV emission
J. Sanz-Forcada, B. Stelzer, M. Coffaro +2
Chromospheric activity cycles are common in late-type stars; however, only a handful of coronal activity cycles have been discovered. \ihor\ is the most active and youngest star wi…
Activity and rotation of the X-ray emitting Kepler stars
Daniele Pizzocaro, Beate Stelzer, Ennio Poretti +6
The relation between magnetic activity and rotation in late-type stars provides fundamental information on stellar dynamos and angular momentum evolution. Rotation/activity studies…
Diagnosing the Clumpy Protoplanetary Disk of the UXor Type Young Star GM Cephei
P. C. Huang, W. P. Chen, M. Mugrauer +29
UX Orionis stars (UXors) are Herbig Ae/Be or T Tauri stars exhibiting sporadic occultation of stellar light by circumstellar dust. GM\,Cephei is such a UXor in the young (~M…
