High - mass YSO
نویسنده
چکیده
High-mass star formation is not well understood chiefly because examples are deeply embedded, relatively distant, and crowded with sources of emission. Using VLA and VLBA observations of H 2 O and SiO maser emission, we have mapped in detail the structure and proper motion of material 20–500 AU from the closest high-mass YSO, radio source I in the Orion KL region. We observe streams of material driven in a rotating, wide angle, bipolar wind from the surface of an edge-on accretion disk. The example of source I provides strong evidence that high-mass star formation proceeds via accretion.

متن کاملExtended CH3OH maser flare excited by a bursting massive YSO
Aims. Recently, substantial flaring in the 6.7 GHz methanol maser line has been observed toward the high-mass young stellar object (YSO) S255 NIRS 3, where an accretion burst was also detected in the IR. Our goal is to study the change in the properties of the 6.7 GHz masers between the preand outburst phases, and investigate the connection between the maser and the accretion burst. Methods. Wi...
متن کاملHigh - resolution NIR Observations of the Circumstellar Disk System in the Bok Globule CB 26 1
We report on results of near-infrared and optical observations of the mm disk embedded in the Bok globule CB 26 (Launhardt & Sargent 2001). The near-infrared images show a bipolar reflection nebula with a central extinction lane which coincides with the mm disk. Imaging polarimetry of this object yielded a polarization pattern which is typical for a young stellar object surrounded by a large ci...
متن کاملThe Dense Molecular Cores in the IRAS 21391+5802 region
We present a detailed kinematical study and modeling of the emission of the molecular cores at ambient velocities surrounding IRAS 21391+5802, an intermediate-mass protostar embedded in IC 1396N. The high-density gas emission is found in association with three dense cores associated with the YSOs BIMA 1, BIMA 2, and BIMA 3. The CS (J=5→4) and CH3OH (J=5−1 →4−1) emission around BIMA 1 has been m...
متن کاملThe Stellar-Disk Electric (Short) Circuit: Observational Predictions for a YSO Jet Flow
Abstract We discuss the star-disk electric circuit for a young stellar object (YSO) and calculate the expected torques on the star and the disk. We obtain the same disk magnetic field and star-disk torques as given by standard magnetohydrodynamic (MHD) analysis. We show how a short circuit in the star-disk electric circuit may produce a magnetically-driven jet flow from the inner edge of a disk...
