An Outbursting Protostar: The Environment of L1251 VLA 6

The Astrophysical Journal
Young protostars that undergo episodic accretion can provide insight into the impact on their circumstellar environments while matter is accreted from the disk onto the protostar.

A Search for and Characterization of Young Stellar Objects in N206, An H II Complex in the Large Magellanic Cloud

, 2011
I have identified 51 young stellar object candidates in N206, an H II complex in the nearby Large Magellanic Cloud galaxy. Using archival images from the Spitzer Space Telescope, supplemented with other infrared and optical images, I located point ...

IRAS22150+6190: A POORLY STUDIED YOUNG STAR

Odessa Astronomical Publications, 2016
Many young stellar objects have been discovered in the course of the InfraRed Astronomical Satellite (IRAS) mission, which observed almost the entire sky in four photometric bands between 12 and 100 microns in 1989.

Young Stellar Objects in NGC 6823

, 2011
NGC 6823 is a young open cluster that lies at a distance of ~2 kpc in the Vulpecula OB1 association. Previous studies using CCD photometry and spectroscopy have identified a Trapezium system of bright O- and B-type stars at its center. We present optical, near-infrared and Spitzer photometric observations of the cluster. Our survey reaches down to I~22

LAMOST Reveals Long-lived Protoplanetary Disks

The Astronomical Journal
While both observations and theories demonstrate that protoplanetary disks are not expected to live much longer than ∼10 Myr, several examples of prolonged disks have been observed in the past.

The Pre-outburst Properties of the FU Ori Object HBC 722

The Astrophysical Journal Letters
FU Ori outbursts are thought to play an important role in stellar assembly and the evolution of protoplanetary disks. However, the progenitor young stellar objects are largely uncharacterized.

The Early History of Stellar Spin: the Theory of Accretion onto Young Stellar Objects

EPJ Web of Conferences, 2014
The interaction of the magnetospheres of forming stars with their surrounding protostellar disks results in magnetospheric accretion flow onto the star. How is the associated angular momentum of accreting material channelled? The resolution of this issue
