Dispersed T Tauri stars and galactic star formation
AIP Conference Proceedings, 1996 The spatial distribution, age distribution and kinematics of T Tauri stars, both close to and widely distributed around active clouds, are considered using simple models of T Tauri dispersal. Models are compared to observations in and around the nearby cloud complexes, in particular the recent discovery of widely scattered young stars from the ROSAT ...

HOT GAS LINES IN T TAURI STARS
The Astrophysical Journal Supplement Series, 2013 ABSTRACT For Classical T Tauri Stars (CTTSs), the resonance doublets of N v, Si iv, and C iv, as well as the He ii 1640 Å line, trace hot gas flows and act as diagnostics of the accretion process. In this paper we assemble a large high-resolution, high-sensitivity data set of these lines in CTTSs and Weak T Tauri Stars (WTTSs).

The Astrophysical JournalThe 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.

Dynamical investigations of the multiple stars
Open Astronomy, 2017 Two multiple stars - the quadruple star - Bootis (ADS 9173) and the triple star T Taury were investigated. The visual double star - Bootiswas studied on the basis of the Pulkovo 26-inch refractor observations 1982-2013.

Rotational Evolution of Classical T Tauri Stars: Models and Observations
The Astrophysical JournalWe 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
EPJ Web of Conferences, 2014 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 Astrophysical JournalThe 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.

Evidence for Dust Depletion in a Misaligned Protoplanetary Disk with JWST
The Astrophysical Journal LettersHere 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
