Long-term, uniform series of UBVR observations of T Tauri and Herbig Ae stars obtained
over 20 yr at the Maidanak Observatory as part of the ROTOR program are analyzed. We find
a linear relationship...
On the source of dense outflows from T Tauri Stars. and III. Winds driven from the star-disc shear layer

2010/11/11
Ultraviolet observations of classical T Tauri Stars (cTTSs) have shown that there is a hot (Te ≃ 80, 000 K) and dense (ne ≃ 1010 cm−3) component associated with the large scale jet. ...
Origins of the H, He I, and Ca II Line Emission in Classical T Tauri Stars
Solar and Stellar Astrophysics (astro-ph.SR)

We perform local excitation calculations to obtain line opacities and emissivity ratios and compare them with observed properties of H, He I, O I, Ca II, and Na I lines to determine the density, tempe...
