PROGRAM_ABSTRACT_BEG
The hot Jupiter orbiting the 2Myr wTTauri star V830 Tau has widened our view on the planetary formation and migration and offers a great laboratory to study how stars and planets evolve and interact during the first Myr of their life. Now that we demonstrated the reality of the RV planetary signal of V830 Tau using several independent techniques [Donati et al. 2016], we aim at characterizing the system better and putting constraints on the physical processes at work in these early stages of a planetary system. With the aid of optical and nIR radial velocity measurements with iSHELL, ESPaDOnS, GRACES coupled with the 2017 Kepler campaign on Taurus, we particularly want to improve the activity modeling of the complex surface of this young star and get better precision on the orbital elements of the planet. We thus need to sample the stellar rotation [2.74d] and the planetary orbital period [4.93d], to get simultaneous nIR RV and activity/magnetic field measurements, for a total of 2hrs per night over a 16 nights window. A moderate precision of up to 10m/s is required [since V830 Tau is a fast rotator]. This program has been accepted in 16b, as a snapshot program [planned observations Jan 4-8]. The proposed observations this semester are our last chance to monitor [full phase coverage] the star using, simultaneously, optical precise photometry [Kepler] and spectroscopic observations.
