CLOSE COMPANIONS TO YOUNG STARS. I. A LARGE SPECTROSCOPIC SURVEY IN CHAMAELEON I AND TAURUS-AURIGA
We present the results of a multiplicity survey of 212 T Tauri stars in the Chamaeleon I and Taurus-Auriga star-forming regions, based on high-resolution spectra from the Magellan Clay 6.5 m telesc
The First Stars
In this review, we outline the current theory for the formation of stars in present-day molecular clouds and then extrapolate this paradigm to earlier generations of stars. We discuss the radiative
STAR FORMATION and the INITIAL MASS FUNCTION
We review the current theory for the formation of stars in molecular clouds. We also discuss the initial mass function; in particular, we present a scaling argument which produces a power-law IMF in
T associations in X-rays
The X-ray emission properties of T Tau type stars and the basic results from the ROSAT X-ray mission are presented. The results of optical follow-up observations of ROSAT sources unidentified with
Multifrequency Monitoring of RU Lupi: Observational Results and a Model
A large campaign of multifrequency observations of the extreme T Tauri star RU Lupi was performed from 1983 to 1988.
X-Rays and Activity in Pre-Main Sequence Stars
Low mass pre-main sequence stars are rapidly rotating and fully convective, the perfect recipe for copious magnetic activity and coronal X-ray emission. EINSTEIN observations revealed a large number
Active Longitudes and Rotation of Active Stars
The interpretation of light curves and line profiles of active stars indicates that surface features exist at different atmospheric heights and these features, assumed as tracers of stellar rotation,
Magnetized Disk-Winds and the Origin of Bipolar Outflows.
Interstellar magnetic fields play certainly a distinct role in star formation and in galactic molecular disks. These magnetic fields are, however, also a key ingredient for accretion disks around
Observational Properties of Jets from Young Stars
In this paper the observational properties of the jets and collimated outflows from young stellar objects are reviewed, emphasizing the most recent observational results. Among the topics discussed
Properties and Models of T Tauri Stars
This lecture provides (i) a short discussion of observational properties of T Tauri stars as well as a brief reminder of past ideas related to interpreting these observations; (ii) an introduction to

T Tauri stars and dust clouds in a region of the GUM nebula.
Photometric, spectroscopic and infrared observations are presented of 16 H-alpha emission-line stars in the Gum nebula.  Nine of the stars were found to be T Tauri stars.  They are located in a par
Radio and Infrared Properties of Young Stars
The observations and the theory of the radio and infrared emission from pre-main-sequence stars are reviewed and discussed.
Some Aspects of T Tauri Variability
A review is presented of light variations of T Tauri stars in ultraviolet, visible and infrared light. Special attention is given to variability connected to stellar rotation and pulsation and to
BLUESHIFTED FORBIDDEN LINES IN T TAURI STARS.
The authors report observational evidence for a predominance of blueshifts among the radial velocities of the forbidden lines in the spectra of T Tauri stars. The similarities of the velocity
Cool stars, stellar systems and the Sun
These conference proceedings focus on cool stars, stellar systems and the Sun. Individual papers deal with star clusters, star evolution, and star models. Particular attention is paid to binary stars.
Line profiles of T Tauri stars - Clues to the nature of the mass flow
A set of high resolution observations of the H..cap alpha.., Na D, He I lambda5876, and H..gamma.. lines in several T Tauri stars is presented. Repeated observations of some of these objects yield
The disks of T Tauri stars with flat infrared spectra
The energy distributions of T Tauri stars with flat infrared spectra is modeled by assuming that they have spatially thin disks with unorthodox radial gradients of temperature. Derived model
Near-Infrared Spectra of 11 T Tauri Stars
We present preliminary results of a spectrophotometric study of 11 T Tauri stars in the near infrared, the principal aim being the study of the Ca II triplet behaviour. The stars we have observed
Observations of suspected low-mass post-T Tauri stars and their evolutionary status
We present the results of five X-ray discovered weak emission pre-main-sequence stars in the Taurus-Auriga star formation complex. All are of spectral type K7-M0, and about 1--2 mag above the main
