Scientific paper

The maximum loss rates of hydrogen from planetary atmospheres resulting from the heat input from solar extreme UV radiation and from a T-Tauri-like solar wind were 0.001-0.0001 parts of the planetary mass for the terrestrial planets and 10 to the -7th to 10 to the -8th parts for the outer planets. The mass loss rates due to a planetary wind are two to four times larger. The present extreme UV radiation of the sun or heating from the T-Tauri-like solar wind is not adequate to dissipate the protoplanetary nebula in the terrestrial region.
