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…
The mass distribution of clumpy accretion onto the nearby young star TW Hya
Tao Ji, Javier Serna, Gregory J. Herczeg +12
The proliferation of high time-resolution and decades-long monitoring of classical T Tauri stars provides a vast opportunity to test the variability of the star-disk connections. H…
PROJECT-J: the shocking H2 outflow from HH46
Maria Gabriela Navarro, Brunella Nisini, Teresa Giannini +14
We analyze the H2 emission observed in the HH46 Class I system as part of PROJECT-J (Protostellar Jets Cradle Tested with JWST), to investigate the origin and excitation of the war…
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…
Evidence of a Disk-wind Origin for Fluorescent H in Classical T Tauri Stars
Matt Kalscheur, Kevin France, Brunella Nisini +8
We use FUV spectra of 36 T Tauri stars, predominately from 's ULLYSES program, to examine the kinematic properties of fluorescent H emission li…
