Determining Dust Properties in Protoplanetary Disks: SED-derived Masses and Settling with ALMA
The Astrophysical Journal, 2023 We present spectral energy distribution (SED) modeling of 338 disks around T Tauri stars from 11 star-forming regions, ranging from ∼0.5 to 10 Myr old.

The variability of T Tauri stars [PDF]
Symposium - International Astronomical Union, 1990 For many years we have monitored the variability of some bright T Tauri stars with the 0.6 m “Perkin telescope” at Van Vleck Observatory. Collaborators in this endeavor have included several astronomers at the Crimea Astrophysical Observatory, at Capidomonte Observatory, at the U.S. Naval Observatory, and even some sophisticated amateurs.

Observational Constraints on the Formation and Evolution of Binary Stars [PDF]
, 2001 We present a high spatial resolution UV to NIR survey of 44 young binary stars in Taurus with separations of 10-1000 AU. The primary results include: (1) The relative ages of binary star components are more similar than the relative ages of randomly ...

LIGHT CURVE TYPES OF CLASSIC T TAURI STARS
Odessa Astronomical Publications, 2016 By using the archive photometric data’s obtained for a long time intervals we have carried out a master light curves of 28 classical T Tauri type stars. For the physical character of variability mainly 5 type light curves can be separated.

Discovery of a New Molecular Bubble–Outflow Structure in the Taurus B18 Cloud
The Astrophysical Journal, 2023 Star formation can produce bubbles and outflows, as a result of stellar feedback. Outflows and bubbles inject momentum and energy into the surrounding interstellar medium, and so are related to the overall energy balance of the molecular cloud. Molecular

Connection between jets, winds and accretion in T Tauri stars: the X-shooter view [PDF]
, 2017 We have analysed the [OI]6300 A line in a sample of 131 young stars with discs in the Lupus, Chamaeleon and signa Orionis star forming regions, observed with the X-shooter spectrograph at VLT. The stars have mass accretion rates spanning from 10^{-12} to

MAGNETOSPHERIC ACCRETION IN T TAURI STARS: OBSERVATIONAL TEST
Odessa Astronomical Publications, 2017 In the classical T Tauri stars (CTTS) the magnetic field plays an important role in the interaction between the star and the accretion disk. In 1996-2000 we have carried out an extensive spectroscopic and photometric monitoring of the extremly active ...

Stellar energetic particle ionization in protoplanetary disks around T Tauri stars [PDF]
, 2017 Context. Anomalies in the abundance measurements of short lived radionuclides in meteorites indicate that the protosolar nebulae was irradiated by a large number of energetic particles ( E ≳ 10 MeV).

High-energy radiation from T Tauri stars [PDF]
, 2011 T Tauri stars are young, low mass, pre-main sequence stars surrounded by an accretion disk. These objects present strong magnetic activity and powerful magnetic reconnection events.

Observational Tests of Magnetospheric Accretion Models in Young Stars
EPJ Web of Conferences, 2014 Magnetically controlled accretion of disk material onto the surface of Classical T Tauri stars is the dominant paradigm in our understanding of how these young stars interact with their surrounding disks.
