Two Very Massive Young Stars in Early Formation Stages

چکیده
We present K-band spectra of the near infrared counterparts to IRS2E and IRS2W which is associated with the ultracompact HII region W51d, both of them embedded sources in the Galactic compact HII region W51 IRS2. The high spatial resolution observations were obtained with the laser guide star facility and Near infrared Integral Field Spectrograph (NIFS) mounted at the Gemini North observatory. The spectrum of the ionizing source of W51d shows the photospheric

Brown Dwarf Disks With
We present ALMA continuum and spectral line data at 0.89 mm and 3.2 mm for three disks surrounding young brown dwarfs and very low mass stars in the Taurus star forming region. Dust thermal emission is detected and spatially resolved for all the three disks, while CO(J = 3 − 2) emission is seen in two disks. We analyze the continuum visibilities and constrain the disks physical structure in dus...
متن کاملOBSERVATIONS AND MODELING OF THE 2 – 25 μm EMISSION FROM HIGH MASS PROTOSTELLAR OBJECT CANDIDATES
This is a report on detailed modeling of young high-mass protostellar candidates during their most embedded and obscured phases. We performed narrowband mid-infrared imaging of three candidate high-mass protostellar objects in G11.94-0.62, G29.96-0.02, and G45.07+0.13 at Gemini Observatory using the Thermal-Region Camera and Spectrograph (T-ReCS). The sources were imaged through up to 11 narrow...
متن کاملThe “missing” YSOs in the central parsec of the Galaxy: evidence for star formation in a massive accretion disk and a top-heavy IMF
Few dozens of young high mass stars orbit Sgr A∗ at distances as short as ∼ 0.1 parsec, where star formation should be quenched by the strong tidal shear from Sgr A∗. The puzzling young stellar population is believed to come into existence in one of the two ways: (i) “normal” star formation at several tens of parsec in a very massive star cluster that then spiraled in, or (ii) star formation in...
متن کاملVery Cold and Massive Cores near Isoss J18364-0221: Implications for the Initial Conditions of High-mass Star-formation
We report the discovery of two very cold and massive molecular cloud cores in the region ISOSS J18364-0221. The object has been identified by a systematic search for very early evolutionary stages of high-mass stars using the 170μm ISOPHOT Serendipity Survey (ISOSS). Submm continuum and molecular line measurements reveal two compact cores within this region. The first core has a temperature of ...

Studying outflows from young massive star-forming clusters allows one to deduce physical processes that lead to the formation of the most massive stars. I will review the current state of high-spatial-resolution in-terferometric (sub-)mm studies of massive molecular outflows and their implications for high-mass star formation. A possible evolutionary scenario for massive outflows with highly co...
