Aims. We examine whether ejection phenomena from accreting T Tauri stars can be described by only one type of self-collimated jet model. Methods. We present analytical kinematic predictions valid soon after the Alfven surface for all types of steady magnetically s elf-confined jets. Results. We show that extended disc winds, X-winds, and stellar winds occupy distinct regions in the poloidal speed vs. specific an gular momentum plane. Comparisons with current observations of T Tauri jets yield…

Resolved Inner Jets from T Tauri Stars
Understanding how jets are generated around an accreting object is of wide interest to the astrophysical community. A viable way to test observationally the proposed theories is to investigate the
Nonradial and nonpolytropic astrophysical outflows - IX. Modeling T Tauri jets with a low mass-accretion rate
Context. A large sample of T Tauri stars exhibits optical jets, approximately half of which rotate slowly, only at ten per cent of their breakup velocity. The disk-locking mechanism has been shown to
What does it take to launch self-confined jets from astrophysical accretion discs?
Abstract Well collimated jets are observed from young stellar objects (YSO), active galactic nuclei (AGN) and some galactic compacts objects (X-ray Binaries). These jets are powerful in the sense
On the origin of jets from disc-accreting magnetized stars
A brief review of the origin of jets from disc-accreting rotating magnetized stars is given. In most models, the interior of the disc is characterized by a turbulent viscosity and magnetic
On the source of dense outflows from T Tauri stars – III. Winds driven from the star–disc shear layer
Ultraviolet observations of classical T Tauri Stars (cTTSs) have shown that there is a hot (T(e) similar or equal to 80 000 K) and dense (n(e) similar or equal to 1010 cm-3) component associated with
Accretion-powered Stellar Winds. II. Numerical Solutions for Stellar Wind Torques
In order to explain the slow rotation observed in a large fraction of accreting pre-main-sequence stars (CTTSs), we explore the role of stellar winds in torquing down the stars. For this mechanism to
Braking down an accreting protostar: disc-locking, disc winds, stellar winds, X-winds and Magnetospheric Ejecta
Classical T Tauri stars are low mass young forming stars that are surrounded by a circumstellar accretion disc from which they gain mass. Despite this accretion and their own contraction that should
Classical T Tauri stars are pre-main-sequence objects that undergo simultaneous accretion, wind outflow, and coronal X-ray emission. The impact of plasma on the stellar surface from magnetospheric
Molecule survival in magnetized protostellar disk winds - I. Chemical model and first results
Context. Molecular counterparts to atomic jets have recently been detected within 1000 AU of young stars at early evolutionary stages. Reproducing these counterparts is an important new challenge for
Jets from Young Stars: The Need for MHD Collimation and Acceleration Processes
This lecture revisits in the light of recent data the main lines of evidence indicating that MHD processes play a crucial role in jets from young stars. Measurements of jet collimation and jet


Time-dependent Accretion by Magnetic Young Stellar Objects as a Launching Mechanism for Stellar Jets
A time-dependent jet launching and collimating mechanism is presented. Initial results of numerical simulations of the interaction between an aligned dipole rotator and a conducting circumstellar
Rotation of jets from young stars: New clues from the Hubble Space Telescope Imaging Spectrograph
We report findings from the first set of data in a current survey to establish conclusively whether jets from young stars rotate. We observed the bipolar jets from the T Tauri stars TH 28 and RW Aur
Atomic t tauri disk winds heated by ambipolar diffusion
We summarize results on the thermal and ionization structure of self-similar, magnetically-driven, atomic disk winds heated by ambipolar diffusion. We improve upon earlier work by Safier by
Magnetocentrifugally driven flows from young stars and disks. 3: Numerical solution of the sub-Alfvenic region
We construct steady, axisymmetric, numerical models of the sub-Alfvenic regions of cool winds driven by the X-celerator mechanism. We find that smooth acceleration to speeds of the order of the
Magnetocentrifugally driven flows from young stars and disks. 1: A generalized model
We propose a generalized model for stellar spin-down, disk accretion, and truncation, and the origin of winds, jets, and bipolar outflows from young stellar objects. We consider the steady state
Helium Emission from Classical T Tauri Stars: Dual Origin in Magnetospheric Infall and Hot Wind
High-resolution emission-line profiles of He I and He II in 31 classical T Tauri stars are analyzed with the aim of probing the environs of the star-disk interface in accreting low-mass young stars.
Locating the Launching Region of T Tauri Winds: The Case of DG Tau
It is widely believed that T Tauri winds are driven magnetocentrifugally from accretion disks close to the central stars. The exact launching conditions are uncertain. We show that a general relation
Accretion-powered Stellar Winds as a Solution to the Stellar Angular Momentum Problem
We compare the angular momentum extracted by a wind from a pre-main-sequence star to the torques arising from the interaction between the star and its Keplerian accretion disk. We find that the wind
Predicted rotation signatures in MHD disc winds and comparison to DG Tau observations
Motivated by the first detections of rotation signatures in the DG Tau jet (Bacciotti et al. [CITE]), we examine possible biases affecting the relation between detected rotation signatures and true
The kinematic relationship between disk and jet in the DG Tauri system
We present high angular resolution millimeter wavelength continuum and 13 CO(2–1) observations of the circumstellar disk surrounding the T Tauri star DG Tauri. We show that the velocity pattern in
