Most existing studies of the angular momentum evolution of young stellar populations have focused on the youngest (1-3 Myr) T Tauri stars. In contrast, the angular momentum distributions of older T Tauri stars (4-10 Myr) have been less studied, even ...

Very Low Mass Stars and Brown Dwarfs in Taurus-Auriga
We present high resolution optical spectra obtained with the HIRES spectrograph on the Keck I telescope of low mass T Tauri stars and brown dwarfs (LMTTs) in Taurus-Auriga.

The surface magnetic fields of pre-main-sequence stars and zero-age main-sequence stars are notably strong, resulting in the generation of numerous spots and the emission of bright chromospheric lines.

T Tauri and FU Orionis Stars [PDF]
A great deal of information on the continuous radiation of T Tau- and similar type stars has been acquired. The cause of the ultraviolet and infrared excess emission is discussed. The possibility that the blue continuum may arise from numerous line emissions is considered.

Rotational Evolution of Classical T Tauri Stars: Models and Observations
We developed a grid of stellar rotation models for low-mass and solar-type classical T Tauri stars (CTTS; 0.3 M _⊙ < M _* < 1.2 M _⊙ ). These models incorporate the star–disk interaction and magnetospheric ejections to investigate the evolution of the ...

Observable Signatures of Classical T Tauri Stars Accreting in an Unstable Regime
We discuss key observational signatures of Classical T Tauri stars (CTTSs) accreting through Rayleigh-Taylor instability, which occurs at the interface between an accretion disk and a stellar magnetosphere.

The accretion/ejection processes in T Tauri stars are fundamental to their physical evolution, while also impacting the properties and evolution of the circumstellar material at a time when planet formation takes place.

Optical Monitoring of T Tauri Stars [PDF]
At the Van Vleck Observatory of Wesleyan University, Middletown, Connecticut, we have initiated a program of monitoring T Tauri stars with the 24-inch reflector (Perkin Telescope). During the first observing season, we have obtained UBVRI and Hα (30Å and 150Å) data for five stars: T Tau, RY Tau, SU Aur, RW Aur, and CO Ori.

Evidence for Dust Depletion in a Misaligned Protoplanetary Disk with JWST
Here we report the detection of dust depletion in a misaligned inner disk around UX Tau A using JWST MIRI spectra. Mid-infrared (MIR) continuum “seesaw” variability was detected in this disk by Spitzer and attributed to variable shadows cast on the outer
