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…
A Multi-wavelength, Multi-epoch Monitoring Campaign of Accretion Variability in T Tauri Stars from the ODYSSEUS Survey. III. Optical Spectra
John Wendeborn, Catherine C. Espaillat, Thanawuth Thanathibodee +20
Classical T Tauri Stars (CTTSs) are highly variable stars that possess gas- and dust-rich disks from which planets form. Much of their variability is driven by mass accretion from…
Episodic eruptions of young accreting stars: the key role of disc thermal instability due to Hydrogen ionisation
Sergei Nayakshin, Fernando Cruz Saenz de Miera, Agnes Kospal +3
In the classical grouping of large magnitude episodic variability of young accreting stars, FUORs outshine their stars by a factor of 100, and can last for up to centuries;…
The ODYSSEUS Survey. Motivation and First Results: Accretion, Ejection, and Disk Irradiation of CVSO 109
C. C. Espaillat, G. J. Herczeg, T. Thanathibodee +59
The Hubble UV Legacy Library of Young Stars as Essential Standards (ULLYSES) Director's Discretionary Program of low-mass pre-main-sequence stars, coupled with forthcoming data fro…
The Ionized Nebula surrounding the Red Supergiant W26 in Westerlund 1
Nicholas J. Wright, Roger Wesson, Janet E. Drew +7
We present Hαimages of an ionized nebula surrounding the M2-5Ia red supergiant (RSG) W26 in the massive star cluster Westerlund 1. The nebula consists of a circumstellar shell or…
