CO Outflows from Young Stellar Objects [PDF]
The Astrophysical Journal, 2002 We have mapped the CO J = 1-0 emission from molecular outflows associated with six young stellar systems using the BIMA array. The systems are all relatively nearby, have low-luminosity, and range from Class 0 to Class II sources. The CO outflows in these systems are complicated, showing multipolar structures, multiple cavities, and asymmetric lobes ...

Young Stellar Object Candidates in IC 417
The Astronomical Journal, 2023 IC 417 is in the Galactic plane, and likely part of the Aur OB2 association; it is ∼2 kpc away. Stock 8 is one of the densest cluster constituents; off of it to the east, there is a “nebulous stream” (NS) that is dramatic in the infrared (IR).

Outbursts of young stellar objects [PDF]
Monthly Notices of the Royal Astronomical Society, 2004 We argue that the outbursts of the FU Orionis stars occur on timescales which are much longer than expected from the standard disc instability model with _{c} \gtrsim 10^{-3}. The outburst, recurrence, and rise times are consistent with the idea that the accretion disc in these objects is truncated at a radius R_{i} \sim 40 \rsun. In agreement with a

Stable Coronal X-Ray Emission over 20 yr of XZ Tau
The Astronomical Journal, 2023 XZ Tau AB is a frequently observed binary young stellar object in the Taurus Molecular Cloud; XZ Tau B has been classified as an EXOr object. We present new Chandra/HETG-ACIS-S observations of XZ Tau AB, complemented with variability monitoring of the ...

YOUNG STELLAR OBJECTS IN THE GOULD BELT [PDF]
The Astrophysical Journal Supplement Series, 2015 We present the full catalog of Young Stellar Objects (YSOs) identified in the 18 molecular clouds surveyed by the Spitzer Space Telescope "cores to disks" (c2d) and "Gould Belt" (GB) Legacy surveys. Using standard techniques developed by the c2d project, we identify 3239 candidate YSOs in the 18 clouds, 2966 of which survive visual inspection and form ...

YOUNG STELLAR CLUSTERS CONTAINING MASSIVE YOUNG STELLAR OBJECTS IN THE VVV SURVEY [PDF]
The Astronomical Journal, 2016 ABSTRACT The purpose of this research is to study the connections of the global properties of eight young stellar clusters projected in the Vista Variables in the Via Lactea (VVV) ESO Large Public Survey disk area and their young stellar object (YSO) populations.

A Gigantic Mid-infrared Outburst in an Embedded Class I Young Stellar Object J064722.95+031644.6
The Astrophysical Journal, 2023 We report the serendipitous discovery of a giant mid-infrared outburst from a previously unknown source near a star-forming region in the constellation Monoceros.

X3: A High-mass Young Stellar Object Close to the Supermassive Black Hole Sgr A*
The Astrophysical Journal, 2023 To date, the proposed observation of young stellar objects (YSOs) in the Galactic center still raises the question of where and how these objects could have formed due to the violent vicinity of Sgr A*.
