Spatially resolved magnetic field structure in the disk of a T Tauri star
Nature, 2014Magnetic fields in accretion disks play a dominant part during the star formation process but have hitherto been observationally poorly constrained. Field strengths have been inferred on T Tauri stars and possibly in the innermost part of their accretion

Naked T Tauri stars and post T Tauri stars
2008It has become evident during the past few years that there is more to low mass pre-main sequence (PMS) stellar populations than the classical T Tauri stars (TTS). If all low mass stars pass through the T Tauri phase, and star formation continues for a dynamical timescale, then in a typical star formation region the post-T Tauri (PTT), PMS stars should ...

T Tauri Stars, Pre-T Tauri Stars, and Stellar Jets [PDF]
, 1987 The properties of the pre-main-sequence T Tauri stars are described in relation to the likely properties of their predecessors. These predecessors, the “pre-T Tauri stars”, are thought to be the stars responsible for exciting Herbig-Haro objects. Pre-T Tauri stars are capable of generating “stellar jets” by which bipolar flows carry material out into ...

T Tauri stars: an overview [PDF]
Reports on Progress in Physics, 1984 The review presents the main aspects of the body of knowledge on T Tauri variable stars, which are presumed to be young, gravitationally contracting low-mass stars. The author first reviews their often exotic properties in the different wavelength ranges accessible to modern astronomy and discuss the data's immediate interpretation.

The T Tauri stars have always been somewhat mysterious, displaying a bewildering variety of spectral peculiarities and variability. They are relatively faint, yet demand the highest quality observations to help unravel their puzzles. In the last few years they have been studied with a new level of detail and in a developing context of star formation ...

The Ultraviolet Variability of the T Tauri Stars
Astrophysics and Space Science, 1998T Tauri stars (TTSs) show enhanced ultraviolet (UV) continuum and line emission with respect to main sequence stars of similar spectral types (Imhoff & Appenzeller 1989; Gomez de Castro, 1998). There is mounting evidence of this excess being produced by the release of gravitational energy from infalling material (Bertout et al 1988, Simon et al 1990 ...

, 2001 Several problems of the theory of the RV Tauri stars are reviewed on the basis of the numerical nonlinear modelling. We analyse the nature of the alternating pulsations of these variables, and discuss their relation to the period doubling phenomenon in W Virginis stars.
