Evidence for Differential Rotation on a T Tauri Star [PDF]

open access: yes, 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.

A hot Jupiter orbiting a 2-million-year-old solar-mass T Tauri star [PDF]

open access: yesNature, 2016
Hot Jupiters are giant Jupiter-like exoplanets that orbit their host stars 100 times more closely than Jupiter orbits the Sun. These planets presumably form in the outer part of the primordial disk from which both the central star and surrounding planets

Evolutionary status of T Tauri stars [PDF]

open access: yesResearch in Astronomy and Astrophysics, 2018
The problem of the determination of T Tauri stars masses and ages using their evolutionary status is discussed. We test of pre-main sequence evolutionary models of D'Antona \& Mazzitelli (1994), Dotter et al. (2008), Bressan et al. (2012) and Chen et al. (2014), Baraffe et al.

Determining Dust Properties in Protoplanetary Disks: SED-derived Masses and Settling with ALMA

open access: yesThe Astrophysical Journal, 2023
We present spectral energy distribution (SED) modeling of 338 disks around T Tauri stars from 11 star-forming regions, ranging from ∼0.5 to 10 Myr old.

Searching for Magnetospheres around Herbig Ae/Be Stars

open access: yesUniverse, 2021
We describe four different approaches for the detection of magnetospheric accretion among Herbig Ae/Be stars with accretion disks. Studies of several unique objects have been carried out.

Star–Disk Interactions in Multiband Photometric Monitoring of the Classical T Tauri Star GI Tau [PDF]

open access: yes, 2017
The variability of young stellar objects is mostly driven by star–disk interactions. In long-term photometric monitoring of the accreting T Tauri star GI Tau, we detect extinction events with typical depths of mag that last for days to months and often ...

Magnetospheric accretion in the intermediate-mass T Tauri star HQ Tauri [PDF]

open access: yesAstronomy & Astrophysics, 2019
Context. Classical T Tauri stars are pre-main sequence stars surrounded by an accretion disk. They host a strong magnetic field, and both magnetospheric accretion and ejection processes develop as the young magnetic star interacts with its disk. Studying

Magnetic fields and accretion flows on the classical T Tauri star V2129 Oph [PDF]

open access: yes, 2007
From observations collected with the ESPaDOnS spectropolarimeter, we report the discovery of magnetic fields at the surface of the mildly accreting classical T Tauri star V2129 Oph.

Circular polarization in T Tauri stars [PDF]

open access: yesThe Astrophysical Journal, 1986
We report the detection of circular polarization in three T Tauri stars with known intrinsic linear polarization. A circumstellar origin is required.
