... The effect is strongest in the most evolved, high-latitude supergiant V5112 Sgr=IRAS19500-1709, which has an extended structured envelope (Figs.1 and 2). In the optical spectrum of this object, the BaII ion lines are split into three components (Figs.3 and 4). ... Thus, we discovered for the first time the enrichment of the stellar envelope with heavy metals produced at the AGB stage. ... Detection of heavy-metal lines in the spectrum of the circumstellar envelope of a post-AGB star. ...

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. ...

Irregular structure of the envelope around the carbon-rich star TX Psc A. Heske, P. te Lintel Hekkert and P.R. Maloney Circumstellar envelopes of seven oxygen and carbon rich late-type stars were resolved by mapping with the 30m IRAM telescope in the (2-1) and (1-0) transitions of carbon monoxide. Six of them were found to be extended of about 40''. ...

. To the IUM main page . We will discuss the question of approximation of the Wiener loop of linear size L by its convex envelope. It turns out that the degree of such approximation is L^(1/3), and not the "usual" L^(1/2).

... 1) The MS lower envelopes for groups of stars with different metallicities turn out to be coincident. ... 4) The conformation of the kinematics of stars within narrow ranges ob b-y with the ages derived from isohrones reveals that, at Z < Z , the isohrone ages seem to be increasingly overestimated with growing b-y . ... At a given metallicity, they have a much narrower MS and the locus of their MS lower envelope seems to be brighter for the metal-rich group of stars. ...

NGC 3918 is in the constellation Centaurus and is about 3,000 light-years from us. Its diameter is about 0.3 light-year. It shows a roughly spherical outer envelope but an elongated inner balloon inflated by a fast wind from the hot central star, which is starting to break out of the spherical envelope at the top and bottom of the image.

An artist's conception showing a blue straggler being created by mass transfer in a binary star system. The giant star, seen in the upper left of the illustration, has lost hold of its outer envelope. ... Soon the giant star will donate the remainder of its envelope, leaving only the half-solar-mass white dwarf core (shown peaking through the giant's tenuous envelope) as the companion to the blue straggler.

Figure 5: The location of CPDтИТ20 1123 on the log g T eff diagram, compared with normal sdB stars (Edelmann et al. 2003), helium-rich sdB stars (Ahmad Jeffery 2003; Naslim et al. 2010), helium-rich sdO stars (Stroeer et al. ... We present a fine analysis of the bright intermediate helium sdB star CPDтИТ20 1123 (Albus 1) which shows it to be cool, for a hot subdwarf, with T eff 23 000 K and with a surface helium abundance 17 per cent by number. ...

Electrolysis of Ices as a Key to Understanding of the Minor Bodies' Nature . ... The electrolysis of dirty ices constituting massive envelopes of Ganymede-like bodies is shown to be crucial for understanding of (explosive) origin and manifestations of different types of minor bodies and related objects in the inner Solar System. ...
