Three-dimensional Simulations of Magnetospheric Accretion in a T Tauri Star: Accretion and Wind Structures Just Around the Star [PDF]
The Astrophysical Journal, 2022 We perform three-dimensional (3D) magnetohydrodynamic simulations of magnetospheric accretion in a T Tauri star to study the accretion and wind structures in the close vicinity of the star.

A Third Star in the T Tauri System [PDF]
, 2000 New speckle-holographic images of the T Tauri Infrared Companion (T Tauri IRC; T Tauri S) reveal it to be a double system with a sky-projected separation of 0".05, corresponding to a linear distance of 7 AU.

Evidence for Differential Rotation on a T Tauri Star [PDF]
, 2006 Five years of photometric monitoring of the T Tauri star HBC 338 in NGC 1333 has revealed that it is a periodic variable, but the period has changed significantly with time.

X-ray emission from MP Muscae: an old classical T Tauri star [PDF]
, 2007 We study the properties of X-ray emitting plasma of MP Mus, an old classical T Tauri star. We aim at checking whether an accretion process produces the observed X-ray emission and at deriving the accretion parameters and the characteristics of the shock ...

The HH30 edge-on T Tauri star [PDF]
Astronomy & Astrophysics, 2018 Context. The disk-outflow connection is thought to play a key role in extracting excess angular momentum from a forming protostar. HH30 is a rare and beautiful example of a pre-main sequence star exhibiting a flared edge-on disk, an optical jet, and a CO

Placing the Spotted T Tauri Star LkCa 4 on an HR Diagram [PDF]
, 2017 Ages and masses of young stars are often estimated by comparing their luminosities and effective temperatures to pre-main-sequence stellar evolution tracks, but magnetic fields and starspots complicate both the observations and evolution.

A hot Jupiter around the very active weak-line T Tauri star TAP 26 [PDF]
, 2017 We report the results of an extended spectropolarimetric and photometric monitoring of the weak-line T Tauri star TAP 26, carried out within the MaTYSSE programme with the ESPaDOnS spectropolarimeter at the 3.6 m Canada-France-Hawaii Telescope.

V1094 Scorpii: A rare giant multi-ringed disk around a T Tauri star [PDF]
Astronomy & Astrophysics, 2018 Context. A wide variety of ring-like dust structures have been detected in protoplanetary disks, but their origin and frequency are still unclear. Aims. We aim to characterize the structure of an extended, multi-ringed disk discovered serendipitously in ...

Magnetospheric accretion and spin-down of the prototypical classical T Tauri star AA Tau [PDF]
, 2010 From observations collected with the ESPaDOnS spectropolarimeter at the Canada-France-Hawaii Telescope (CFHT) and with the NARVAL spectropolarimeter at the Telescope Bernard Lyot (TBL), we report the detection of Zeeman signatures on the prototypical ...

Non-stationary dynamo and magnetospheric accretion processes of the classical T Tauri star V2129 Oph [PDF]
, 2011 We report here the first results of a multiwavelength campaign focussing on magnetospheric accretion processes of the classical T Tauri star V2129 Oph. In this paper, we present spectropolarimetric observations collected in 2009 July with ESPaDOnS at the
