Theoretical studies of mass loss and shock phenomena in cool star envelopes [PDF]

open access: yes
To show the difficulty of producing the blue-shifted emission of (O I) and (S II) from T Tauri stars directly in the stellar wind, an element of gas in a radially expanding stellar wind was followed as it cooled and recombined.

A Multiwavelength, Multiepoch Monitoring Campaign of Accretion Variability in T Tauri Stars from the ODYSSEUS Survey. II. Photometric Light Curves

open access: yesThe Astrophysical Journal
Classical T Tauri stars (CTTSs) are young, low-mass stars that accrete material from their surrounding protoplanetary disk. To better understand accretion variability, we conducted a multiepoch, multiwavelength photometric monitoring campaign of four ...

Evidence of a Disk Wind Origin for Fluorescent H2 in Classical T Tauri Stars

open access: yesThe Astronomical Journal
We use far-ultraviolet spectra of 36 T Tauri stars, predominately from the Hubble Space Telescope (HST) ULLYSES program, to examine the kinematic properties of fluorescent H _2 emission lines for evidence of disk outflows.
