- W2296332015 abstract "We studied 102 star forming regions in seven spiral galaxies (NGC 628, NGC 783, NGC 2336, NGC 6217, NGC 6946, NGC 7331, and NGC 7678) on the basis of complex spectroscopic, photometric (UBVRI) and spectrophotometric (H alpha line) observations. Using data on the chemical composition and absorption in HII regions, obtained from spectroscopic observations, and using evolutionary models, we estimated physical parameters (ages and masses) of young stellar groupings embedded in HII regions. We found that the gas extinction, A(gas), which determined from the Balmer decrement, does not correspond in some cases to the absorption A(stars) in the young stellar associations (complexes). This is due to the spatial offset relative HII cloud the stellar group related to him. It has been found that the condition A(gas) = A(stars) does not satisfied for the star forming regions, in which: 1) the contribution to the total emission of gas in the B and/or V bands is higher than 40%, and 2) EW(H alpha) > 1500A. Extinction A(V) in studied star forming regions corrected for the Galactic absorption A(V)Gal ranges from 0 to 3 mag with a mean value A(V)-A(V)Gal = 1.18+-0.84 mag. We estimated masses and ages for 63 star forming regions. The regions have ages from 1 to 10 Myr, the most part of them are younger than 6 Myr. The derived masses of young stellar groupings range from 10^4Msun in the nearby galaxies NGC 628 and NGC 6946 to 10^7Msun in the most distant NGC 7678. More than 80% of groupings have masses between 10^5Msun and 10^6Msun. The lowest mass estimate of 1x10^4Msun for the objects in NGC 628 and NGC 6946 belongs to the mass interval of the youngest Galactic open clusters." @default.
