NIKA2 observations of dust grain evolution from star-forming filament to T-Tauri disk: Preliminary results from NIKA2 observations of the Taurus B211/B213 filament [PDF]

EPJ Web of Conferences
To understand the evolution of dust properties in molecular clouds in the course of the star formation process, we constrain the changes in the dust emissivity index from star-forming filaments to prestellar and protostellar cores to T Tauri stars. Using

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.

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.

Magnetic fields of intermediate-mass T Tauri stars [PDF]

Astronomy & Astrophysics, 2017
Context. The origin of the fossil magnetic fields detected in 5 to 10% of intermediate-mass main sequence stars is still highly debated.Aims. We want to bring observational constraints to a large population of intermediate-mass pre-main sequence (PMS ...

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.

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

Disks Around T Tauri Stars [PDF]

International Astronomical Union Colloquium, 1994
AbstractA variety of evidence suggests that at least 50% of T Tauri stars are surrounded by disks of gas and dust. Inferred disk properties are compatible with those generally attributed to the solar nebula, before the formation of planets. Millimeter-wave aperture synthesis mapping of molecular line and dust continuum emission from T Tauri stars ...

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).

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 ...

A Population of Dipper Stars from the Transiting Exoplanet Survey Satellite Mission

The Astrophysical Journal Supplement Series, 2022
Dipper stars are a classification of young stellar objects that exhibit dimming variability in their light curves, dropping in brightness by 10%–50%, likely induced by occultations due to circumstellar disk material.
