Discovery of a New Molecular Bubble–Outflow Structure in the Taurus B18 Cloud
The Astrophysical Journal, 2023 Star formation can produce bubbles and outflows, as a result of stellar feedback. Outflows and bubbles inject momentum and energy into the surrounding interstellar medium, and so are related to the overall energy balance of the molecular cloud. Molecular

Placing the Spotted T Tauri Star LkCa 4 on an HR Diagram [PDF]
, 2017 Ages and masses of young stars are often estimated by comparing their luminosities and effective temperatures to pre-main-sequence stellar evolution tracks, but magnetic fields and starspots complicate both the observations and evolution.

First scattered light detection of a nearly edge-on transition disk around the T Tauri star RY Lupi [PDF]
Astronomy & Astrophysics, 2018 Context. Transition disks are considered sites of ongoing planet formation, and their dust and gas distributions could be signposts of embedded planets.

Tracing episodic accretion with NOEMA: FU Orionis-type stars and their millimeter environment [PDF]
EPJ Web of Conferences, 2022 The earliest phases of star formation are characterised by intense mass accretion from the circumstellar disk to the central star. One group of lowmass young stellar objects, FU Orionis-type stars (FUors) exhibit accretion rate peaks accompanied by ...

A CANDIDATE YOUNG MASSIVE PLANET IN ORBIT AROUND THE CLASSICAL T TAURI STAR CI TAU [PDF]
, 2016 The ∼2 Myr old classical T Tauri star CI Tau shows periodic variability in its radial velocity (RV) variations measured at infrared (IR) and optical wavelengths.

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

NIKA2 observations of dust grain evolution from star-forming filament to T-Tauri disk: Preliminary results from NIKA2 observations of the Taurus B211/B213 filament [PDF]
EPJ Web of ConferencesTo understand the evolution of dust properties in molecular clouds in the course of the star formation process, we constrain the changes in the dust emissivity index from star-forming filaments to prestellar and protostellar cores to T Tauri stars. Using

Twenty-five Years of Accretion onto the Classical T Tauri Star TW Hya
The Astrophysical Journal, 2023 Accretion plays a central role in the physics that governs the evolution and dispersal of protoplanetary disks. The primary goal of this paper is to analyze the stability over time of the mass accretion rate onto TW Hya, the nearest accreting solar-mass ...

Inner disk structure of the classical T Tauri star LkCa 15 [PDF]
Astronomy & Astrophysics, 2018 Context. Magnetospheric accretion has been thoroughly studied in young stellar systems with full non-evolved accretion disks, but it is poorly documented for transition disk objects with large inner cavities. Aims.

International Astronomical Union Colloquium, 1990 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.
