Binarity in massive young stellar objects

, 2021
Most massive stars (up to 100%) are thought to be in binary systems. The multiplicity of massive stars seems to be intrinsically linked to their formation and evolution, and so Massive Young Stellar Objects are key in observing this early stage of star formation.

The Disk Orientations of Perseus Protostellar Multiples at ∼8 au Resolution

The Astrophysical Journal
We present a statistical characterization of circumstellar disk orientations toward 12 protostellar multiple systems in the Perseus molecular cloud using the Atacama Large Millimeter/submillimeter Array at Band 6 (1.3 mm) with a resolution of ∼25 mas (∼8

Young stellar objects detected by IRAS

The Astrophysical Journal Supplement Series, 1991
Fluxes of 453 IRAS point sources selected for proximity to dense gas have been accurately determined by co-adding IRAS data. From this set, 258 sources are detected in all four bands: 12, 25, 60, and 100 microns. As distance from dense molecular material increases, these sources exhibit systematic trends in color and a markedly decreasing luminosity ...

Molecular Outflows from Young Stellar Objects [PDF]

, 1993
After summarizing the basic properties of molecular outflows, I discuss several important issues that have seen recent theoretical or observational advance, namely: the outflow structure and velocity field, implications of outflow energetics on the nature of proto-stellar winds, Extremely High Velocity neutral components, and the evolutionary status of

A Unified Model for Bipolar Outflows from Young Stars: Kinematic and Mixing Structures in HH 30

The Astrophysical Journal
The young stellar source HH 30 is a textbook example of an ionic optical jet originating from a disk in an edge-on system shown by the Hubble Space Telescope.

A Framework for Modeling the Evolution of Young Stellar Objects

The Astrophysical Journal
Measuring properties of young stellar objects (YSOs) is necessary for probing the pre-main-sequence evolution of stars. As YSOs exhibit complex geometry, measurement generally entails comparing observed radiation to template populations of radiative ...

Characterizing the Multiple Protostellar System VLA 1623-2417 with JWST, ALMA, and VLA: Outflow Origins, Dust Growth, and an Unsettled Disk

The Astrophysical Journal
Utilizing the James Webb Space Telescope (JWST), the Atacama Large Millimeter/submillimeter Array (ALMA), and the Very Large Array (VLA), we present high angular resolution (0 $\mathop{.}\limits^{^{\prime\prime} }$ 06–0 $\mathop{.}\limits^{^{\prime\prime}
