Scientific paper

The interaction of a T-Tauri-like solar wind and the protoplanetary cloud is studied on the basis of an analytical model for the cloud hydrostatic structure. The solar wind is approximated by a radial ideal gas flow without magnetic fields. Cloud density in the equatorial plane is assumed to be constant. Cloud gravitation is taken to be negligible with respect to that of the sun. With a mass loss rate of approximately 10 to the -8th power M/year, the sun would lose about 0.1 M during 10 to the 7th power years by the T-Tauri-like solar wind. It is felt that the wind would be capable of blowing away all the gas from a cloud which has not been accreted by the planets since protoplanetary cloud mass could not exceed 0.1 M.
