Spectroscopic and photometric variability of a CTTS: HQ Tau

We studied the spectroscopic and photometric variation of the Classical T Tauri Star (CTTS) HQ Tau. We used the spectroscopic data from ESPaDOnS, the echelle spectrometer mounted at the Canada-France-Hawaï Telescope (CFHT), and the photometric data from the Kepler K2 mission. We first determined HQ Tau's stellar parameters, using ZEEMAN code and CESTAM models. We then looked for a periodic variability in the HQ Tau's lightcurve and spectrum through periodogram analysis, radial velocity, veiling, and emission line study. Finally we interpret the results obtained and try to connect spectroscopic and photometric variability within the framework of magnetospheric accretion.
