Evolutionary status of T Tauri stars [PDF]
Research 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.

Time-variable Jet Ejections from RW Aur A, RY Tau, and DG Tau
The Astrophysical Journal Supplement Series, 2022 We present Gemini-NIFS, Very Large Telescope-SINFONI, and Keck-OSIRIS observations of near-IR [Fe ii ] emission that are associated with well-studied jets from three active T Tauri stars—RW Aur A, RY Tau, and DG Tau—taken from 2012 to 2021.

Characterising the surface magnetic fields of T Tauri stars with high-resolution near-infrared spectroscopy [PDF]
Astronomy & Astrophysics, 2019 Aims. In this paper, we aim to characterise the surface magnetic fields of a sample of eight T Tauri stars from high-resolution near-infrared spectroscopy.

JWST Detects Neon Line Variability in a Protoplanetary Disk
The Astrophysical Journal Letters, 2023 We report the first detection of variability in the mid-infrared neon line emission of a protoplanetary disk by comparing a JWST Mid-InfraRed Instrument Medium Resolution Spectrometer spectrum of SZ Cha taken in 2023 with a Spitzer Infrared Spectrograph ...

Circular polarization in T Tauri stars [PDF]
The 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.

High-energy radiation from T Tauri stars [PDF]
, 2011 T Tauri stars are young, low mass, pre-main sequence stars surrounded by an accretion disk. These objects present strong magnetic activity and powerful magnetic reconnection events.

The –M disk Relationship for Herbig Ae/Be Stars: A Lifetime Problem for Disks with Low Masses?
The Astronomical Journal, 2023 The accretion of material from protoplanetary disks onto their central stars is a fundamental process in the evolution of these systems and a key diagnostic in constraining the disk lifetime. We analyze the relationship between the stellar accretion rate

International Astronomical Union Colloquium, 1995 This review concerns rapid variability, on time-scales of a few hours or less, occurring on T Tauri stars (TTS). There are several recent reviews on observed properties of TTS (e.g. Appenzeller & Mundt 1989, Bertout 1989, Gahm 1990a, Kuhi & Cram 1989), some with more emphasis on “flare-like” activity (Feigelson et al.

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