SPHERE/SHINE reveals concentric rings in the debris disk of HIP 73145
M. Feldt, J. Olofsson, A. Boccaletti +22
The debris disk of HIP73145 has been detected in scattered light in the near-IR, and at far-IR wavelengths before, but no substructure has been seen so far. Detection of such subst…

Dimitri Mawet, Élodie Choquet, Olivier Absil +22
HD 141569 A is a pre-main sequence B9.5 Ve star surrounded by a prominent and complex circumstellar disk, likely still in a transition stage from protoplanetary to debris disk phas…
Binaries among low-mass stars in nearby young moving groups
Markus Janson, Stephen Durkan, Stefan Hippler +5
The solar galactic neighbourhood contains a number of young co-moving associations of stars (so-called `young moving groups') with ages of ~10--150 Myr, which are prime targets for…
Multiplicity and clustering in Taurus star-forming region. I. Unexpected ultra-wide pairs of high-order multiplicity in Taurus
Isabelle Joncour, Gaspard Duchêne, Estelle Moraux
We collected the multiplicity data of stars in Taurus to build an up-to-date stellar/multiplicity catalog. After a general study of nearest-neighbor statistics on spatial random di…

The young and nearby star β Pictoris (β Pic) is surrounded by a debris disk composed of dust and gas known to host a myriad evaporating exocomets, planetesimals and at least one pl…
Structure of Herbig AeBe disks at the milliarcsecond scale A statistical survey in the H band using PIONIER-VLTI
B. Lazareff, J. -P. Berger, J. Kluska +26
Context. It is now generally accepted that the near-infrared excess of Herbig AeBe stars originates in the dust of a circumstellar disk. Aims. The aims of this article are to infer…
The ALMA-PILS survey: First detections of ethylene oxide, acetone and propanal toward the low-mass protostar IRAS 16293-2422
J. M. Lykke, A. Coutens, J. K. Jørgensen +14
One of the open questions in astrochemistry is how complex organic and prebiotic molecules are formed. Aims. Our aim is to start the process of compiling an inventory of oxygen-bea…
The Gould's Belt Distances Survey (GOBELINS) I. Trigonometric parallax distances and depth of the Ophiuchus complex
Gisela N. Ortiz-León, Laurent Loinard, Marina A. Kounkel +14
We present the first results of the Gould's Belt Distances Survey (GOBELINS), a project aimed at measuring the proper motion and trigonometric parallax of a large sample of young s…
Investigating the rotational evolution of very low-mass stars and brown dwarfs in young clusters using Monte Carlo simulations
M. J. Vasconcelos, J. Bouvier
Context. Very low-mass (VLM) stars and brown dwarfs (BDs) present a different rotational behaviour from their solar mass counter-parts. Aims. We investigate the rotational evolutio…
CoRoT 223992193: Investigating the variability in a low-mass, pre-main sequence eclipsing binary with evidence of a circumbinary disk
Edward Gillen, Suzanne Aigrain, Caroline Terquem +10
CoRoT 223992193 is the only known low-mass, pre-main sequence eclipsing binary that shows evidence of a circumbinary disk. The system displays complex photometric and spectroscopic…
The hot Jupiter of the magnetically-active weak-line T Tauri star V830 Tau
J. -F. Donati, L. Yu, C. Moutou +16
We report results of an extended spectropolarimetric and photometric monitoring of the weak-line T Tauri star V830 Tau and its recently-detected newborn close-in giant planet. Our…
Violent environment of the inner disk of RW Aur A probed by the 2010 and 2015 dimming events
S. Facchini, C. F. Manara, P. C. Schneider +5
RW Aur is a young binary system showing strong signatures of a recent tidal encounter between the circumprimary disk and the secondary star. The primary star has recently undergone…
CSI 2264: Investigating rotation and its connection with disk accretion in the young open cluster NGC 2264
L. Venuti, J. Bouvier, A. M. Cody +7
The low spin rates measured for solar-type stars at an age of a few Myr (~10% of the break-up velocity) indicate that some mechanism of angular momentum regulation must be at play…
The MiMeS survey of magnetism in massive stars: Magnetic analysis of the O-type stars
J. H. Grunhut, G. A. Wade, C. Neiner +9
We present the analysis performed on spectropolarimetric data of 97 O-type targets included in the framework of the MiMeS (Magnetism in Massive Stars) Survey. Mean Least-Squares De…
A revised moving cluster distance to the Pleiades open cluster
P. A. B. Galli, E. Moraux, H. Bouy +3
Aims: We provide a new distance estimate for the Pleiades based on the moving cluster method, which will be useful to further discuss the so-called Pleiades distance controversy an…
Discovery of a Hot Corino in the Bok Globule B335
