Stellar Rotation of T Tauri Stars in the Orion Star-forming Complex [PDF]

open access: hybridAstrophysical Journal, 2021
We present a large-scale study of stellar rotation for T Tauri stars in the Orion star-forming complex. We use the projected rotational velocity ( vsin(i) ) estimations reported by the APOGEE-2 collaboration as well as individual masses and ages derived ...

Dust Around T Tauri Stars [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2011
To reproduce the multiple broad peaks and the fine spectral features in the spectral energy distributions (SEDs) of T Tauri stars, we model dust around T Tauri stars using a radiative transfer model for multiple isothermal circumstellar dust shells. We

Sodium Ionization in T-Tauri Stars [PDF]

open access: bronzeInternational Astronomical Union Colloquium, 1989
We present the results of a study of the sodium ionization and excitation in the winds of low-luminosity, pre-main-sequence stars. Line profiles for the Nal doublet at 5990,5986 Åare discussed and compared with the observations for those T Tauri stars with P-Cygni profiles.

Erratum: Magnetic topologies of young suns: the weak-line T Tauri stars TWA 6 and TWA 8A [PDF]

open access: bronzeMonthly notices of the Royal Astronomical Society, 2019
We present a spectropolarimetric study of two weak-line T Tauri stars (wTTSs), TWA 6, and TWA 8A, as part of the MaTYSSE (Magnetic Topologies of Young Stars and the Survival of close-in giant Exoplanets) programme. Both stars display significant Zeeman

Dynamical Masses of T Tauri Stars and Calibration of Pre–Main‐Sequence Evolution [PDF]

open access: bronze, 2000
We have used the high sensitivity and resolution of the IRAM interferometer to produce subarcsecond 12CO J = 2-1 images of nine protoplanetary disks surrounding T Tauri stars in the Taurus-Auriga cloud (seven singles and two binaries).

A Multiwavelength, Multiepoch Monitoring Campaign of Accretion Variability in T Tauri Stars from the ODYSSEUS Survey. II. Photometric Light Curves [PDF]

open access: goldThe Astrophysical Journal
Classical T Tauri stars (CTTSs) are young, low-mass stars that accrete material from their surrounding protoplanetary disk. To better understand accretion variability, we conducted a multiepoch, multiwavelength photometric monitoring campaign of four ...

Observations and Modeling of the Inner Disk Region of T Tauri Stars [PDF]

open access: green, 2005
We present observations of four T Tauri stars using long baseline infrared interferometry from the Palomar Testbed Interferometer. The target sources, T Tau N, SU Aur, RY Tau, and DR Tau, are all known to be surrounded by dusty circumstellar disks.

T Tauri stars in blue

open access: yesThe Astronomical Journal, 1993
We present an atlas of 96 low dispersion spectra of T Tauri stars, both classical and weak-lined. The flux-calibrated spectra extend from Hβ to well blueward of the Balmer jump. Observed equivalent widths and rough blue veilings are presented. We model stars with excess emission as a combination of a weak-lined T Tauri star of a similar spectral type ...

GIARPS High-resolution Observations of T Tauri stars (GHOsT). IV. Accretion properties of the Taurus-Auriga young association [PDF]

open access: yesAstronomy & Astrophysics, 2022
In the framework of the GIARPS@TNG High-resolution Observations of T Tauri stars (GHOsT) project, we study the accretion properties of 37 Classical T Tauri Stars of the Taurus-Auriga star forming region (SFR) with the aim of characterizing their relation
