1. Number of accreting X-ray binaries of selected types
... The numbers of three types of compact binaries containing accreting NSs and BHs, which are most interesting from the point of view of their observational appearances, have been calculated as a function of time: i) X-ray transient source containing a NS in an eccentric orbit around a main sequence Be-star (the observed prototype: A0535+26), ii) BH The evolution of the selected types of X-ray binaries during the first 10 million years after the starburst onset is presented in Fig. ...

2. A Search for Clustering around Herbig Ae/Be Stars
... However, while low mass stars are usually found to form in loose groups with densities of a few stars per cubic parsecs, high mass stars are known to form in dense clusters with up to 10000 stars per cubic parsec. ... We have undertaken a survey of a cospicuous number of fields around intermediate mass young stars (Herbig Ae/Be stars, HAeBe) with the aim of detect and characterize the groups of young stars that may have formed together with the HAeBe star. ...

10. Phase I Target Naming Conventions
Target names are used to provide unique designations for the targets that will be used throughout the proposal. These names will generally also be used in Phase II, and ultimately to designate targets in the HST data archive. ... This facility will be most useful if consistent naming conventions are used. ... If a target is not contained in these catalogs, other catalog designations may be used (e.g., 4U X-ray catalog designation, Villanova white-dwarf catalog number, etc.) ... Target Type . ...

17. Globular Clusters: Self-Enrichment
... We address a question if globular clusters (GC) in a protogalaxy could for some time evolve chemically as isolated systems, enriching themselves with heavy elements produced in first supernova events that follow initial star formation. We determine both the critical mass of a protoglobular cluster that is needed to retain the ejecta of the very first supernova, and the critical energy (i.e., number of supernovae) that is needed to expel the residual gas from a cluster of a given mass. ...

All the objects in the database, galaxies, stars, clusters, ..., are indexed with their pgc number. Historically, the pgc numbering was created to unify the names of the galaxies when the database project started in 1983. ... Still, all the objects in the database (about 5 millions) have a pgc number which is used as a unique identification across the different tables. This number should not be used to build a name , since it would not be recognized by any database, including HyperLeda. ...

... GSAOI Home . ... Science . ... Deep imaging at J , H , and K is required to identify all stellar objects, brown dwarfs, and planetary mass objects in the central region of the Orion Nebula Cluster down to masses comparable to that of Jupiter. This is required to establish the initial mass function, i.e., the number of stars of each mass that have formed, in this region of intense massive star formation. ... The fields of the GSAOI detectors are shown as four green squares in each frame. ...
