... Due costellazioni molto brillanti si trovano ai lati opposti della stella polare: l' Orsa Maggiore e Cassiopea . ... La bandiera mostra anche come si fa a trovare la Stella Polare. Immaginate una linea che congiunge le due stelle anteriori del "carro", prolungatela dalla parte dove si trova il "timone", fino a una distanza di 5 volte la distanza tra le due stelle (nella bandiera questa distanza un po' ridotta!), e vi troverete sulla (o molto vicini alla) stella polare. ...

These values are compared to the observed H II region luminosities, yielding an estimate for the mean fraction of H-ionizing photons that escape the local nebulae in this sample. We formally estimate that, overall, 0-51% of the ionizing radiation escapes the local H II regions and is available to ionize the warm, ionized medium in the LMC. ...

... Armagh Observatory, College Hill, Armagh BT61 9DG, +44 (0)28 3752 2928 . ... Radio luminosity - spectral type plot for all ultracool dwarfs observed at 4.9 GHz. ... Whilst no radio emission was detected from any of the targets, significant upper limits were placed on the radio luminosities that are below the luminosities of previously detected ultracool dwarfs. Combining our results with those from the literature gives a detection rate for dwarfs in the spectral range M7 тАУ L3.5 of тИ® 9%. ...

... The earliest X--ray observations were carried out in the mid--1970s. X--ray luminosities of order L erg/sec were detected in the 2-11 keV range in the direction of the Orion star forming region. ... These observations showed that the O and B stars were the brightest X--ray sources, and that TTs were also associated with emission. Feigelson and Kriss (1981) showed that some of the X--ray sources were associated with PMS stars which had not been previously detected which H surveys. ...

... Ultraluminous X-ray sources (ULXs) are located in external galaxies, their X-ray luminosities (10 39 - 10 41 erg/s) are thousand times greater than those of brightest black holes in the Galaxy. ULXs may be supercritical accretion disks around black holes of stellar masses (~10 Solar masses) like that in SS433, or they may be a hypothetical intermediate-mass black holes (hundreds - thousands Solar masses) with standard accretion disks. ... 2) The ULX progenitors were ejected from the star clusters. ...
