Results of magnetic field measurements in young stars DO Tau, DR Tau, DS Tau

Abstract

Results of measurements of the longitudinal magnetic field in a hot accretion spot in three classical T Tauri stars (CTTS) are presented. The magnetic field in the formation region of the narrow component of the emission line HeI 5876 Å was found for each star in our sample at a level of more than 2σ. In case of DS Tau we have found the field in the narrow components of NaI D lines, which was equal to +0.8 \pm 0.3 kG, i.e. it was equal to the field measured on the narrow component of HeI 5876 Å. Our results indicate that the magnetic field in the hot spots can be studied for CTTS down to 13^m that allow in the future to double a number of CTTS with measured field in the accretion zone.
