... Astronomy news . ... NASA's Spitzer Images Out-of-This-World Galaxy . ... It is spiral-shaped like our Milky Way, with long, spindly arms of stars. The "eye" at the center of the galaxy is actually a monstrous black hole surrounded by a ring of stars. In this color-coded infrared view from Spitzer, the area around the invisible black hole is blue and the ring of stars, white. ... The ring around the black hole is bursting with new star formation. ...

Next: Initial parameters of compact Up: The Model Previous: The Model . To start the calculations, we choose the distributions of initial binary parameters: mass of the primary ZAMS component, ; binary mass ratio, ; and orbital separation, a . ... As for the mass ratio distribution in binaries, the observational information is poor. Meanwhile, from the evolutionary point of view, it is particularly important how different are the initial masses of the components (see, e.g., Trimble 1983). ...

HI envelopes around HII regions . ... We have investigated 32 HII regions and around 17 of them we have found the clumped HI envelopes with radial motions. The example of the envelope around HII regions M16 is shown on figure 1. ... The thickness of envelopes is rather great - 0.44 radius, mass are about 6E+4 mass of the Sun, kinetic energies - 10E+50 ergs. ... The model of formation of HI envelope was advanced as outcome of an operation of a summarized stellar wind of stars, exciting HII region. ...

Dust around Herbig Ae/Be Stars: Porous, Cometary-like Grains? ... This brings up the question, which we try to answer here, of how the grain porosity affects the observational manifestations of the dust shells of HAeBe stars: the excess infrared emission, anomalous extinction in the ultraviolet, and the peculiar behaviour of colour indices and linear polarization during deep brightness minima observed for about 25% of HAeBe stars (UX Ori, WW Vul, etc). ...

... Low resolution, slitless spectral images were obtained at the Loiano Observatory in the wavelength window 3300-6420 ?, in order to identify in extragalactic objects targets displaying the most prominent features that characterise the spectrum of bright hot stars, WR and Luminous Blue Variables (LBV), and of nebular regions as well. We present the results with the well studied galaxy M 101, where the previously known H II regions with WR star signatures are easily identified. ...
