Active pre-main-sequence binaries with separations of around 10 stellar radii present a wealth of phenomena unobserved in common systems. The study of these objects is extended from classical T Tauri stars to the Herbig Ae star HD 104237. The primary has a mass 2.2 ± 0.2 M� and secondary 1.4 ± 0.3 M� . Spectrointerferometry with the VLTI/AMBER in the K-band continuum and the Brγ line is presented. It is found that the K-band continuum squared visibilities are compatible with a circumbinary disc… 

A resolved, au-scale gas disk around the B[e] star HD 50138

HD 50138 is a B[e] star surrounded by a large amount of circumstellar gas and dust. Its spectrum shows characteristics which may indicate either a pre- or a post-main-sequence system. Mapping the

The far-infrared behaviour of Herbig Ae/Be discs: Herschel PACS photometry

Herbig Ae/Be objects are pre-main sequence stars surrounded by gas- and dust-rich circumstellar discs. These objects are in the throes of star and planet formation, and their characterisation informs

New Binaries in the ϵ Cha Association

We present Adaptive Optics-aided speckle observations of 47 young stars in the ϵ Cha association made at the 4 m Southern Astrophysical Research Telescope in the I-band. We resolved 10 new binary

AMBER/VLTI high spectral resolution observations of the Brγ emitting region in HD 98922 - A compact disc wind launched from the inner disc region

Context. High angular and spectral resolution observations can provide us with fundamental clues to the complex circumstellar structure of young stellar objects (YSOs) and to the physical processes

Interferometric study on the temporal variability of the brightness distributions of protoplanetary disks

Context. Optical and infrared spatially unresolved multi-epoch observations have revealed the variability of pre-main sequence stars and/or their environment. Moreover, structures in orbital motion

A CO SURVEY IN PLANET-FORMING DISKS: CHARACTERIZING THE GAS CONTENT IN THE EPOCH OF PLANET FORMATION

We carried out a 12CO(3–2) survey of 52 southern stars with a wide range of IR excesses (LIR/L*) using the single-dish telescopes APEX and ASTE. The main aims were (1) to characterize the evolution

The Degree of Alignment between Circumbinary Disks and Their Binary Hosts

All four circumbinary (CB) protoplanetary disks orbiting short-period (P < 20 days) double-lined spectroscopic binaries (SB2s)—a group that includes UZ Tau E, for which we present new Atacama Large

Precession and accretion in circumbinary discs: the case of HD 104237

We present the results of smoothed particle hydrodynamics (SPH) simulations of the disc around the young, eccentric stellar binary HD 104237. We find that the binary clears out a large cavity in the

On the Mass Accretion Rates of Herbig Ae/Be Stars. Magnetospheric Accretion or Boundary Layer?

Understanding how young stars gain their masses through disk-to-star accretion is of paramount importance in astrophysics. It affects our knowledge about the early stellar evolution, the disk

The interferometric view of Herbig Ae/Be stars

In this contribution I review how optical interferometry has contributed to shaping our understanding of the class of Herbig Ae/Be stars and of their associated circumstellar disks. I discuss the

Close pre-main-sequence binary stars are expected to clear central holes in their protoplanetary disks, but the extent to which material can flow from the circumbinary disk across the gap onto the

WALL EMISSION IN CIRCUMBINARY DISKS: THE CASE OF CoKu TAU/4

A few years ago, the mid-IR spectrum of a Weak Line T Tauri Star, CoKu Tau/4, was explained as emission from the inner wall of a circumstellar disk, with the inner disk truncated at ∼10 AU. Based on
