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.

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 ...

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

X-ray Photoevaporation-starved T Tauri Accretion [PDF]
, 2009 X-ray luminosities of accreting T Tauri stars are observed to be systematically lower than those of non-accretors. There is as yet no widely accepted physical explanation for this effect, though it has been suggested that accretion somehow suppresses ...

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 Magnetically Driven Disk Wind in the Inner Disk of PDS 70
The Astrophysical Journal, 2023 PDS 70 is so far the only young disk where multiple planets have been detected by direct imaging. The disk has a large cavity when seen at submillimeter and near-infrared wavelengths, which hosts two massive planets. This makes PDS 70 the ideal target to

Very Low Mass Stars and Brown Dwarfs in Taurus-Auriga
, 2002 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.

A Three Micron Survey of the Chamaeleon I Dark Cloud [PDF]
, 2001 We describe an L-band photometric survey of 0.5 square deg of the Cha I dark cloud. The survey has a completeness limit of L < 11.0. Our survey detects 124 sources, including all known pre-main sequence stars with L < 11.

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.
