A Pre-Main Sequence Binary Viewed Through its Circumbinary Disk: A New Phase for KH 15D
Catrina M. Hamilton, Adi B. Chacko, George A. Carson +16
The binary T Tauri system, KH 15D, is poised to provide unprecedented detail of gas and ices located between 3-5 AU of its circumbinary disk over the next few years. We analy…
A survey for variable young stars with small telescopes - XI. Spot Lifetimes and Coverage Distributions
Dirk Froebrich, Carys Herbert, Aleks Scholz +47
We present a homogeneous analysis of rotational variability and spot properties in young stellar objects across multiple star-forming regions observed by the Hunting Outbursting Yo…
Extended Ionized Fe Objects in the UWIFE Survey
Kim Yesol, Koo Bon-Chul, Pyo Tae-Soo +7
We explore systematically the shocked gas in the first Galactic quadrant of the Milky Way using the United Kingdom Infrared Telescope (UKIRT) Wide-field Infrared Survey for Fe+ (UW…
The Outbursting YSOs Catalogue (OYCAT)
C. Contreras Peña, J. -E. Lee, G. Herczeg +39
YSOs can display unpredictable and high-amplitude rises in brightness that can last from a few months to possibly over 100 years. These types of outbursts are explained by large ch…
A survey for variable young stars with small telescopes: X -- Comparing stochastic YSO light curve
Benjamin W. Ryan, Holly Stokes-Geddes, Dirk Froebrich
Light curves of young stars exhibit photometric variability over hours to decades and across a wide range of amplitudes. On time scales beyond a few rotation periods, these light c…
