Информация о статье Текст статьиАннотация
We present phase-reference EVN observations that are part of a program to study the radio emission and kinematics of a sample of stars belonging to the AB Doradus moving group. 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 M⊙. Among the stars included in our program, we emphasize the results obtained in the stellar system HD 160934 A/c.

AB - We present phase-reference EVN observations that are part of a
program to study the radio emission and kinematics of a sample of
stars belonging to the AB Doradus moving group. 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 M⊙. Among the stars
included in our program, we emphasize the results obtained in the
stellar system HD 160934 A/c.
