The lithium abundance of the T Tauri star BP Tauri
The Astrophysical Journal, 1991 The Li abundance of the T Tauri star BP Tau is determined from both the Li I 6707 and 6103 features, using high-accuracy observations and recent model atmospheres. Other work, based solely on analysis of the 6707 line, has found very high Li abundances in T Tauri stars.

Characterising the magnetospheric accretion process of DF Tauri’s primary
Astronomy & AstrophysicsContext. The accretion process in young stellar objects (YSOs) is fundamental to the formation of stellar systems. This process governs the star’s mass assembly, the transfer of angular momentum, and the shaping of the protoplanetary disc, thereby ...

Can Post T Tauri Stars Be Found? Yes! [PDF]
, 2001 I review the observational challenges of finding post T Tauri stars (PTTS), defined here as low-mass, pre-main-sequence stars with ages of 10(7)-10(8) yr.

ALMA High-resolution Observation for the Transitional Disk Around IRAS 04125+2902
The Astrophysical JournalRecently, the youngest transiting planet was discovered around the T Tauri star, IRAS 04125+2902, in the Taurus-Auriga star-forming region. This system is crucial for understanding the early stages of planet formation.

X-ray emission from MP Muscae: an old classical T Tauri star
, 2007 Aims:We study the properties of X-ray emitting plasma of MP Mus, an old classical T Tauri star. We check whether an accretion process could produce the observed X-ray emission and we derive the accretion parameters and the characteristics of the shock ...

TIC 290061484: A Triply Eclipsing Triple System with the Shortest Known Outer Period of 24.5 Days
The Astrophysical JournalWe have discovered a triply eclipsing triple-star system, TIC 290061484, with the shortest known outer period, P _out , of only 24.5 days. This “eclipses” the previous record set by λ Tauri at 33.02 days, which held for 68 yr.

Orbits and masses in the T Tauri system
, 2008 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 We combined astrometric positions from the literature with previously unpublished VLT observations.

The Magnetic Fields on T Tauri Stars
, 2008 T Tauri stars are low mass, pre-main sequence stars, many of which are still surrounded by active accretion disks where it is believed planet formation is currently under way.

X-ray emitting T Tauri stars in the L1551 cloud [PDF]
, 1995 Low mass pre-main sequence stars in the nearby Lynds 1551 star forming cloud are studied with the ROSAT and ASCA X-ray satellites. An 8 ksec ROSAT image reveals 38 sources including 7 well-known T Tauri stars, 2 likely new weak-lined T Tauri stars, 5 ...

High-Resolution X-Ray Spectroscopy of the Post-T Tauri Star PZ Telescopii
, 2004 We present an analysis of the Chandra High Energy Transmission Grating Spectrometer observation of the rapidly rotating (Prot=0.94days) post-T Tauri (~20 Myr old) star PZ Telescopii, in the Tucana association. Using two different methods, we have derived
