... However, the comparison of masses deduced from the continuum SIMBA 1.2 mm emission and virial masses (understood to trace the entire potential of the clouds) in a sample of giant molecular clouds in the Small Magellanic Cloud (SMC) by previous studies found a discrepancy between these two quantities that requires explanation. ... Methods: New observations of the southwest region of the SMC were obtained with the LABOCA camera on the APEX telescope. ...

Star formation is often best manifested by bright H II regions.These are regions of hydrogen which have been ionized by ultraviolet photons which are emitted from massive stars (typically stars more than 20 times the mass of the Sun). ... A narrowband filter image centered on this wavelength will then readily reveal these H II regions and hence the current sites of star formation in a galaxy, The luminous blobs that can be seen here are all H II regions . ...

... 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. ...

PHYSICAL AND CHEMICAL STRUCTURE OF HIGH MASS STAR FORMING REGIONS I.I. Zinchenko Institute of Applied Physics of the Russian Academy of Sciences 46 Uljanov str., ... Basic physical properties of detected clumps and molecular abundances were derived. ... In particular, we found that in regions of high mass star formation the CS emission correlates well with the dust continuum emission and is therefore a good tracer of the total mass while the N 2 H + distribution is frequently very di#erent. ...

... We report on our ongoing project ``Infrared Study of HII Regions Associated with Small Clouds.' ... These IR data, combined with optical imaging (which will be obtained from the IAC-80 telescope), IRAS survey maps, and existing CO observations of the associated clouds, will allow us to undertake a detailed investigation of the gas-to-dust mass ratio, initial mass function and the star-formation efficiency in these complexes. ...

Next: Low-Mass Star Formation Up: M.D. Smith Previous: M.D. Smith Contents . Massive stars are of elevated importance in our Universe for several reasons. ... During their lives, they influence the nurseries in which new stars might form. ... He and Michael Smith investigated the consequences of massive star formation in one such region of our Galaxy. They uncovered that massive stars are forming in the Rosette Molecular Complex at a rate way beyond previous expectations. ...

Large-scale activity in solar eruptive events of October-November 2003 by SOHO/EIT data . ... We analyze large-scale disturbances associated with extremely powerful flares and coronal mass ejections (CMEs) occurred during two passages across the solar disk of a grandiose complex of three active regions in October–November 2003 using SOHO/EIT imaging data. ... In events repeating with short time intervals, the main dimmings observed show clear homology by their form and location. ...

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. ...
