标题： Physical parameters of stellar population in star formation regions of galaxies

摘要： 我们展示了对与HII区域相关的年轻未分辨恒星聚集（簇、OB星协及其复合体）的研究结果，基于光谱、测光和H{\alpha }光谱测光观测的结合。 除了我们自己的观测数据外，我们还使用了文献和开放数据库中部分光谱和H{\alpha }数据。 该研究基于我们之前编纂的19个旋涡星系中1510个形成恒星区域的目录，这些区域的年龄约为10-20 Myr。 我们研究了恒星聚集的形态及其与相关H{\alpha }辐射区的关系。 测量了消光、气体化学丰度和恒星形成区域的大小。 使用针对金属丰度固定为所研究恒星形成区域固有颜色计算的数值SSP模型，我们估计了400个年轻恒星聚集的恒星族年龄和质量。 讨论了恒星形成区域中年轻恒星种群的观测参数与物理参数之间的不同关系。 显示英文摘要

摘要： We present the results of a study of young unresolved stellar groupings (clusters, OB associations, and their complexes) associated with HII regions, based on the coupling of spectroscopic, photometric and H{\alpha} spectrophotometric observations of star formation regions. Along with our own observations, we use a part of the spectroscopic and H{\alpha} data from the literature and open databases. The study is based on the catalogue of 1510 star formation regions with ages ~10-20 Myr in 19 spiral galaxies, compiled by us earlier. We study the morphology of stellar groupings and their relation with the associated H{\alpha} emission region. Extinctions, gas chemical abundances, and sizes of star formation regions are measured. Using numerical SSP models computed for metallicities fixed from observations to intrinsic colours of the studied star formation regions, we estimated ages and masses of stellar population of 400 young stellar groupings. Different relations between observational and physical parameters of the young stellar population in star formation regions are discussed.
