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 ...

Abstract The observational aspects of T Tau stars are described, treating data in the optical, infrared, radio, X-ray and ultraviolet regions of the spectrum. Erratic flare-like behaviour is very characteristic of these objects which are pre-main-sequence stars, mostly on their convective tracks, and represent early phases in the evolution of roughly

T Tauri Stars, Pre-T Tauri Stars, and Stellar Jets
1987The 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 ...

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 ...

T Tauri Stars: The X-ray Connection
Astrophysics and Space Science, 1998The launch of ROSAT opened a new era in the study of T Tauri stars. Prompted by the IUE results, the new X-ray data confirms the existence of extremely high levels of activity in these young stars, very likely of magnetic nature. We address a detailed analysis of the star TW Hya in the X-ray spectral range.

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.

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
