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 ...

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.

Rotation of T Tauri Stars Revisited
Astrophysics and Space Science, 1998This paper reviews the rotation of T Tauri stars. It summarizes the results of a complete bibliographical survey of all photometric and spectroscopic data available in connection with rotation studies of these stars. It is shown that T Tauri stars are slow rotators. More than half of the stars in the sample have been found to have v sin i < 25 km/s.

An introduction to T Tauri stars
2008These lectures are meant as an introduction to some basic physical processes taking place in T Tauri stars. The first section is devoted to a brief description of the various optically visible objects encountered in molecular clouds, and also gives a short overview of early studies of young stellar objects.

Observations of Flare Stars and T Tauri Stars
Publications of the Astronomical Society of Australia, 1967Photographic observations of Flare Stars in association with Slee, Higgins and Patston, T Association patrols, photographic photometry of selected variable stars in association with Bateson of New Zealand and surveillance of comets brighter than V = 13m, in association with Candy of the United Kingdom constitute the principal fields of research of Page
