Abstract
Gas–star complexes introduced by Efremov and Sitnik (1988) are approximated by ellipsoids. The total mass and the mean density of some complexes are estimated from the data on young open cluster sizes and their tidal sizes in the Galaxy gravitational field. The total mass ranges from 0.19 to 120 million solar masses, and the mean density ranges from 0.35 to 3.8 solar masses per cubic parsec.Keywords
