An observational review is provided of the properties of accretion disks around young stars.
It concerns the primordial disks of intermediate-and high-mass young stellar objects in …

We present a substantial extension of the millimeter (mm) wave continuum photometry
catalog for circumstellar dust disks in the Taurus star-forming region, based on a new" …

Estimates of the mass and age of young stars from their location in the HR diagram are
limited by not only the typical observational uncertainties that apply to field stars, but also by …

Aims. We use Gaia Data Release 2 (DR2) to place 252 Herbig Ae/Be stars in the
Hertzsprung–Russell diagram and investigate their characteristics and properties. Methods …

We present a sensitive, multiwavelength submillimeter continuum survey of 153 young
stellar objects in the Taurus-Auriga star formation region. The submillimeter detection rate is …

Abstract The MiMeS (Magnetism in Massive Stars) project is a large-scale, high-resolution,
sensitive spectropolarimetric investigation of the magnetic properties of O-and early B-type …

Abstract Herbig Ae/Be stars (HAeBes) span a key mass range that links low-and high-mass
stars, and thus provide an ideal window from which to explore their formation. This paper …

This is the first in a series of papers in which we describe and report the analysis of a large
survey of Herbig Ae/Be stars in circular spectropolarimetry. Using the ESPaDOnS and …

Abstract We report new Spitzer Space Telescope observations, using the IRAC and MIPS
instruments, of the young (~ 3 Myr) σ Orionis cluster. We identify 336 stars as members of the …

Abstract We present Hubble Space Telescope ultraviolet spectra and supporting ground-
based data for a sample of nine intermediate-mass T Tauri stars (IMTTSs; 1.5–4 M⊙). The …
