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

Post-T Tauri stars: a false problem [PDF]
, 1996 We consider the problem of the apparent lack of old T Tauri stars in low-mass star forming regions in the framework of the standard model of low-mass star formation.

Searching for Magnetospheres around Herbig Ae/Be Stars
Universe, 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.

Evidence for Accretion: High-Resolution X-Ray Spectroscopy of the Classical T Tauri Star TW Hydrae [PDF]
, 2001 We present high-resolution X-ray spectra of the X-ray-bright classical T Tauri star, TW Hydrae, covering the wavelength range of 1.5-25 Å. The differential emission measure derived from fluxes of temperature-sensitive emission lines shows a plasma with a

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

The hot Jupiter of the magnetically active weak-line T Tauri star V830 Tau [PDF]
, 2016 We report results of an extended spectropolarimetric and photometric monitoring of the weak-line T Tauri star V830 Tau and its recently-detected newborn close-in giant planet.

The Mysterious Dimmings of the T Tauri Star V1334 Tau [PDF]
, 2017 We present the discovery of two extended ∼0.12 mag dimming events of the weak-lined T Tauri star V1334. The start of the first event was missed but came to an end in late 2003, and the second began in 2009 February, and continues as of 2016 November ...

Imaging the Haro 6-10 Infrared Companion [PDF]
, 1999 We present an infrared imaging study of the low-mass pre-main-sequence binary system Haro 6-10. This system is one of a handful in which the optically visible primary has the characteristics of a normal T Tauri star, while the secondary is a so-called ...

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

Surface magnetic fields on two accreting T Tauri stars: CV Cha and CR Cha [PDF]
, 2009 We have produced brightness and magnetic field maps of the surfaces of CV Cha and CR Cha: two actively accreting G and K-type T Tauri stars in the Chamaeleon I star-forming cloud with ages of 3-5 Myr.
