摘要: We compare the angular momentum extracted by a wind from pre-main-sequence star to torques arising interaction between and its Keplerian accretion disk. find that alone can counteract spin-up torque mass accretion, solving mystery of why accreting stars are observed spin at less than 10% breakup speed, provided outflow rate in stellar winds is ~10% rate. suggest such massive will be driven some fraction power. For observationally constrained typical parameters classical T Tauri stars, needs few tens percent. In this scenario, efficient braking terminate simultaneously with as usually assumed explain rotation velocities young clusters.
