ABSTRACT:
We present a study of the radio emission and kinematics of a sample of stars belonging to the AB Doradus moving group through VLA and VLBI observations. The main aim of this program is to obtain precise estimates of the dynamical mass of young, low-mass stars, which in combination with photometric measurements will provide precise benchmarks for calibrating pre-main-sequence (PMS) stellar evolutionary models. Calibration of PMS models appears essential, as they are widely used to predict the masses of low mass objects as brown dwarfs and planets. Previous studies show that model predictions are in disagreement with experimental results for masses below 1.2 solar masses. Among the stars included in our program, we emphasize the results obtained in two of them: AB Doradus B and HD 160934.
