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

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.

The ODYSSEUS Survey. Using Accretion and Stellar Rotation to Reveal the Star–Disk Connection in T Tauri Stars

The Astrophysical Journal
Classical T Tauri stars (CTTSs) exhibit strong variability over timescales of minutes to decades. However, much theoretical work assumes that CTTSs are in stable spin states.

JWST MIRI MRS Images of Disk Winds, Water, and CO in an Edge-on Protoplanetary Disk

The Astrophysical Journal Letters
We present JWST MIRI MRS observations of the edge-on protoplanetary disk around the young subsolar-mass star Tau 042021, acquired as part of the Cycle 1 GO program “Mapping Inclined Disk Astrochemical Signatures.” These data resolve the mid-IR spatial ...

VLT/MUSE Detection of the AB Aurigae b Protoplanet with Hα Spectroscopy

The Astrophysical Journal Letters
We analyze high-contrast, medium-spectral-resolution H _α observations of the star AB Aurigae using the Very Large Telescope's Multi Unit Spectroscopic Explorer (MUSE).
