EX Lupi is the prototype of EX Lup-type stars, meaning classical T Tauri stars (cTTSs) showing luminosity bursts and outbursts of 1 to 5 magnitudes lasting for a few months to a few years. These events are ascribed to an episodic accretion that can o

Context. Both the stellar activity and the accretion processes of young stellar objects can induce variations in their radial velocity (RV). This variation is often modulated on the stellar rotation period and may hide a RV signal from a planetary or

The accretion and ejection of mass in pre-main sequence (PMS) stars are key processes in stellar evolution as they shape the stellar angular momentum transport necessary for the stars' stability. Magnetospheric accretion onto classical T Tauri stars

Classical T Tauri stars (CTTSs) are young stellar objects that accrete materials from their accretion disc influenced by their strong magnetic field. The magnetic pressure truncates the disc at a few stellar radii and forces the material to leave the

We aim to characterize the magnetospheric accretion process in the young stellar object V807 Tau, one of the most stable dippers revealed by K2 in the Taurus star forming region. We performed photometric and spectropolarimetric follow-up observations

This work aims to investigate the small-scale magnetic fields of a pair of binary T Tauri stars, V1878 Ori and V4046 Sgr. This is done in order to provide a more complete picture of their magnetic field, as so far only the large-scale structures have

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
