Analytical formulae of the dependence of the velocity and density on the radius during spherical accretion with both mass and momentum inputs, as well as the rate of mass inflow are presented. Some features of gas inflow near the star are discussed, and details of mass loading are presented and calculated as caused by hydrodynamical ablation and conductivity. It looks like that in one example velocities of inflow are in the range from 10-20 km/s (free fall) to 40-50 km/s and the densities are in the range from 2 · 108 (free fall) to 6 · 106 cm−3 at 1017 cm when mass-loading accretion is taken place during formation of 10M⊙ mass star․

Communications of the Byurakan Astrophysical Observatory (ComBAO) is a peer-reviewed scientific journal, which publishes research in observational and theoretical astronomy/astrophysics and presents recent advances in these fields. It is being published by the NAS RA V. Ambartsumian Byurakan Astrophysical Observatory (BAO) in English in electronic form. The journal publishes original papers, review papers, brief reports, book reviews, special communications, observational and theoretical results in various fields of astronomy and related sciences, and some editorial notes, including anniversaries and obituaries. Under the heading “Legacy”, the renewed magazine will republish some old articles of high value in English. The heading “Guest articles” will bring to the attention of readers the articles of researchers who are not employees of BAO. ComBAO was founded in 1946 and regularly published in 1946-1990. However, the publication was interrupted because of the economic situation after the disintegration of the Soviet Union in 1991.
