We present the analysis of high angular resolution Very Large Array radio observations, made at 11 epochs over the last 20 years, of the multiple system T Tauri. One of the sources (Sb) in the system has moved at moderate speed (5-10 km s-1) on an apparently elliptical orbit during the first 15 yr of observations, but after a close (<2 AU) encounter with the source Sa, it appears to have accelerated westward to about 20 km s-1 in the last few years. Such a dramatic orbital change most probably…

Orbit of T Tau Ba-Bb and Mass Estimate for Its Infrared Companion
On the basis of 17 astrometric radio and infrared position measurements almost uniformly covering an arc of 270°, an improved orbit with a period of 33 years and semimajor axis of 0104 (14.6 AU) for
The Orbit of T Tauri South
Abstract We report on previously unpublished diffraction-limited NIR observations of the young binary star T Tauri South. Orbital elements have been estimated by a least–squares fit to the relative
Multiepoch VLBA Observations of T Tauri South
In this Letter, we present a series of seven observations of the compact, nonthermal radio source associated with T Tauri South made with the Very Long Baseline Array (VLBA) over the course of 1
A Single Circumstellar Disk in the SVS 13 Close Binary System
We present Very Large Array observations at 7 mm of the sources IRAS 2A, IRAS 2B, MMS 2, MMS 3, and SVS 13, in the NGC 1333 region. SVS 13 is a young close binary system whose components are
High spatial resolution observations of the T Tau system — I. Astrometry in the near-infrared
T Tauri is an example how our knowledge about an object improves with spatial resolution: About 60 years ago, it was considered to be the prototypical T Tauri star. 25 years ago, it was discovered to
Orbits and masses in the T Tauri system
Aims. We investigate the binary star T Tauri South, presenting the orbital parameters of the two components and their individual masses. Methods. We combined astrometric positions from the literature
Low-Mass Runaway Stars from the Orion Trapezium Cluster
In the course of a search for common proper-motion binaries in the Jones & Walker (JW) catalog of proper motions in the Orion Nebula Cluster, we came across several faint stars with proper motions
The Enigmatic Radio Source T Tauri S
We have observed the T Tau multiple star system using the Multielement Radio-linked Interferometer Network at a frequency of 5 GHz. The compact centimeter wavelength radio emission from T Tau S has
In this article, we present the results of a series of 12 3.6 cm radio continuum observations of T Tau Sb, one of the companions of the famous young stellar object T Tauri. The data were collected
Dynamical Mass Estimates for Incomplete Orbits: Young Multiple Stars in Taurus and Ophiuchus
We present recent measurements of the orbital motion in the binaries DF Tau and ZZ Tau and in the triples Elias 12, T Tau, and V853 Oph. We observed these systems with the Fine Guidance Sensors on


Very Large Array Observations of Proper Motions in L1551 IRS 5
Using high angular resolution (~01) Very Large Array observations made at 2 cm during the period 1983 to 1998, we report the detection of proper motions in the components of the binary radio source

Using high angular resolution (~03) Very Large Array (VLA) observations made at 3.6 cm during the period from 1990 to 2002, we report the detection of proper motions in the components of the binary
Large-scale magnetic fields in the outflow from the young stellar object T Tauri S
T Tauri stars are young stellar objects, similar in mass to the Sun, that are completing the transition between a collapsing cloud and a main-sequence star powered by hydrogen fusion1. Many of these
Orbital proper motions in the protobinary system L1527/IRAS 04368+2557?
Using high angular resolution 7 mm Very Large Array (VLA) observations, we show that the low-mass protostellar object IRAS 043682557 in L1527 is composed of two radio sources separated in projection
The Infrared Companions of T Tauri Stars
The infrared companions (IRCs) associated with several normal low-mass pre-main-sequence (T Tauri) stars pose an interesting problem for theories of binary star formation. The IRCs have very low

Milliarcsecond astrometry provided by Hipparcos and by radio observations makes it possible to retrace the orbits of some of the nearest runaway stars and pulsars to determine their site of origin.
