Primary disks are optically thin end are in state of quasi-magnetostatic equilibrium. They form at the initial stages of isothermal collapse mainly along the magnetic field lines. The sizes, masses and angular momentums of primary disks are determined. Calculations show that, at the time of formation of an optically opaque protostellar disk, the size of the primary disk is 5 000—19 000 AU, and the mass is about 1 % of the initial mass of the cloud.","PeriodicalId":183711,"journal":{"name":"Proceedings of the 48-th International student's conferences \"Physics of Space\"","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116273303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Для объектов, имеющих малое перигелийное расстояние, особое значение имеет оценивание влияния таких возмущающих факторов, как эффект Ярковского и световое давление.

Но темп звездообразования еще зависит и от глубины ямы гравитационного потенциала, и от момента вращения, и от стимулирующего влияния спиральных волн плотности и соседних остатков сверхновых, и от аккреции газа извне.
