Search for young stars among ROSAT All-Sky Survey X-ray sources in and around the R CrA dark cloud [PDF]
, 2000 We present the ROSAT All-Sky Survey data in a 126 deg^2 area in and around the CrA star forming region. With low-resolution spectroscopy of unidentified ROSAT sources we could find 19 new pre-main sequence stars, two of which are classical T Tauri stars,

TRACING SLOW WINDS FROM T TAURI STARS VIA LOW-VELOCITY FORBIDDEN LINE EMISSION [PDF]
, 2016 Using Keck/HIRES spectra (Δ v ∼ 7 km s−1) we analyze forbidden lines of [O i] 6300 Å, [O i] 5577 Å and [S ii] 6731 Å from 33 T Tauri stars covering a range of disk evolutionary stages.

Symposium - International Astronomical Union, 1990 An overview of the characteristics of short-term light variability on T Tauri stars is given. The evidence of the occurrence of flares comes from observations mainly at X-ray energies and from patrole observations in the ultraviolet spectral region.

Probable association of T Tauri stars with the L1014 dense core [PDF]
, 2006 Using the Wide Field Grism Spectrograph 2 (WFGS2), we have carried out slit-less spectroscopy, g'r'i' photometry, and slit spectroscopy on the L1014 dense core. We detected three Halpha emission line stars.

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.

A Survey and Analysis of Spitzer Infrared Spectrograph Spectra of T Tauri Stars in Taurus [PDF]
, 2006 We present mid-infrared spectra of T Tauri stars in the Taurus star-forming region obtained with the Spitzer Infrared Spectrograph (IRS). For the first time, the 5-36 μm spectra of a large sample of T Tauri stars belonging to the same star-forming region

Evidence for grain growth in T Tauri disks [PDF]
, 2003 In this article we present the results from mid-infrared spectroscopy of a sample of 14 T Tauri stars with silicate emission. The qualitative analysis of the spectra reveals a correlation between the strength of the silicate feature and its shape similar

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 ConferencesTo 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

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

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.
