Emission line diagnostics of magnetospheric accretion in young stellar objects
Line emission Stars Accretion Star formation Formation of the accretion flow Stars Magnetic layer
2014/12/9
This thesis seeks to explain the nature of line emission observed in young stellar objects, and to use the lines as diagnostics of the accretion process that is central to star formation. We maintain ...
Multiwavelength study of parsec scale outflows associated with low mass young stellar objects
Arrow flow Low quality of the original star formation Optical observation star
2014/12/9
A multi-wavelength, multi-telescope observational study of recently discovered parsec-scale Herbig-Haro flows associated with the earliest stages of low mass protostellar formation is presented. Impro...
A Southern Sky and Galactic Plane Survey for Bright Kuiper Belt Objects
Southern Sky Galactic Plane Survey Bright Kuiper Objects
2011/10/17
About 2500 square degrees of sky south of declination -25 degrees and/or near the galactic plane were surveyed for bright outer solar system objects. This survey is one of the first large scale southe...
A 95 GHz Class I Methanol Maser Survey Toward GLIMPSE Extended Green Objects (EGOs)
Maser Survey GLIMPSE Extended Green Objects
2011/10/9
We report the results of a systematic survey for 95 GHz class I methanol masers towards a new sample of 192 massive young stellar object (MYSO) candidates associated with ongoing outflows (known as ex...
A Correlation Between Surface Densities of Young Stellar Objects and Gas in Eight Nearby Molecular Clouds
Stellar Objects Gas Nearby Molecular Clouds
2011/9/28
We report the discovery and characterization of a power law correlation between the local surface densities of Spitzer-identified, dusty young stellar objects and the column density of gas (as traced ...
OH Masers and the Dust Emissions Towards High Mass Protostellar Objects
stars: formation masers: OH masers millimeter
2011/9/27
Context: OH maser emission is known to be associated with high mass star forming regions. Towards some of these regions, OH masers are associated with HII regions. Towards others, believed to be in an...
