... The object is remarkable because of its low estimated mass and age and because it is associated with a mid-infrared source, an indication of a surrounding dusty disk. Based on the comparison of our spectrum with similar spectra of field M-dwarfs and atmospheric models, we obtain revised estimates of the spectral type, effective temperature and luminosity of the central object. ...

We present ~1000 new candidate Young Stellar Objects (YSOs) in the Large Magellanic Cloud selected from Spitzer Space Telescope data, as part of the Surveying the Agents of a Galaxy's Evolution (SAGE) Legacy program. ... The candidate YSOs were selected from the SAGE Point Source Catalog from regions of color-magnitude space least confused with other IR-bright populations. ... They are more clustered than generic point sources, as expected if star formation occurs in filamentary clouds or shells. ...

. ArtistтАЩs impression illustrating the formation process of massive stars. At the end of the formation process, the surrounding accretion disk disappears, revealing the surface of the young star. At this phase, the young massive star is much larger than when it has reached a stable equilibrium, i.e., when arriving on the so-called main sequence.

... Ever wonder how solar-mass stars form?. ... In order for material to accrete onto a protostar it has to lose angular momentum. The angular momentum of a large natal cloud leads to the formation of a circumstellar disk and inner accretion disk as the cloud collapses. ... Winds generated in the inner disk or close to the stellar surface (we don't know which) expel material along the disk rotation axis. ... This provides the highest resolution observational data on nearby young stars. ...

... Brown dwarfs are bodies intermediate in mass between stars and planets. ... Recent studies have shown that young brown dwarfs, like young stars, may be surrounded by accretion disks. In some cases these disks appear to be highly evolved, suggesting they are in the early phases of planetary formation. As accretion is often accompanied by outflows in newborn stars, we have been searching for jets from young brown dwarfs. ...

P22P We explore the structures immediately surrounding the high-mass young stellar object S140 IRS 3 within the L1204 molecular cloud. ... The S-shaped structure of this feature can be well reproduced by a model assuming a precessing outflow from IRS 3a. Furthermore, we find several elongated features pointing away from IRS 3 in a southern direction. ...

This is a color composite image made by Karen Gloria at Hopkins Observatory using a 6-inch refractor and a 512x512 element CCD detector. M16 is a young stellar cluster where the radiation of hot stars causes the surrounding hydrogen gas to become ionized. When the electrons and protons recombine a red emission line is given off. The blue nebulosity in this image is associated with preferential scattering of blue light by dust. M16 has an overall angular size of approximately 1/2 a degree.

Next: Conclusions Up: HS 0822+3542 - a Previous: H I and dynamical . The properties of HS 0822+3542 presented above (extremely low abundance of heavy elements, very blue colour of underlying nebulosity, and extremely small mass ratio of stars to neutral gas) suggest that this could be the nearest candidate young dwarf galaxy forming its first stellar generation. ...
