The multiplicity of T Tauri stars in the star forming regions Taurus-Auriga and Ophiuchus-Scorpius: A 2.2 micron speckle imaging survey [PDF]
Astronomical Journal, 1993 We present the results of a magnitude limited (K < =8.5 mag) speckle imaging survey of 69 T Tauri stars in the star forming regions Taurus-Auriga and Ophiuchus-Scorpius. Thirty-three companion stars were found with separations ranging from 0."07 to 2."5;

Classical T Tauri stars: magnetic fields, coronae and star–disc interactions [PDF]
Monthly Notices of the Royal Astronomical Society, 2013 The magnetic fields of young stars set their coronal properties and control their spin evolution via the star-disc interaction and outflows. Using 14 magnetic maps of 10 classical T Tauri stars (CTTSs) we investigate their closed X-ray emitting coronae, their open wind-bearing magnetic fields, and the geometry of magnetospheric accretion flows.

Stellar Winds of Classical T Tauri Stars [PDF]
International Astronomical Union Colloquium, 1997 AbstractWe present calculations of the structure of magnetized winds of classical T Tauri stars (TTSs) in an axisymmetric, stationary, polytropic approximation in a given magnetosphere (i.e. we do not selfconsistently take into account the influence of the flow dynamics on the structure of the underlying magnetosphere). According to the widely accepted

Discovery of Two Different Full Disk Evolutionary Patterns of M-type T Tauri Stars with LAMOST DR8
The Astrophysical Journal, 2023 The full disk, full of gas and dust, determines the upper limit of planet masses, and its lifetime is critical for planet formation, especially for giant planets.

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,

High-resolution [O i] Line Spectral Mapping of TW Hya Consistent with X-Ray-driven Photoevaporation
The Astrophysical Journal Letters, 2023 Theoretical models indicate that photoevaporative and magnetothermal winds play a crucial role in the evolution and dispersal of protoplanetary disks and affect the formation of planetary systems.

Are Both Stars in a Classic T Tauri Binary Classic T Tauri Stars?
The Astrophysical Journal, 1997 Large near-IR color excesses and emission-line spectra indicate the presence of optically thick circumstellar accretion disks and active boundary layers in young stars. We investigate whether this classic T Tauri (TT) behavior is found in one or both members of a binary system previously identified as a TT on the basis of the unresolved light.

Magnetically modulated accretion in T Tauri stars [PDF]
, 1995 We examine how accretion on to T Tauri stars may be modulated by a time-dependent `magnetic gate' where the inner edge of the accretion disc is disrupted by a varying stellar field.
