Insights into star formation and dispersal from the synchronization of stellar clocks
Age is one of the most fundamental parameters of a star, yet it is one of the hardest to determine as it requires modelling various aspects of stellar formation and evolution. When we compare the ages derived ...

A Solar System formation analogue in the Ophiuchus star-forming complex
Anomalies among the daughter nuclei of the extinct short-lived radionuclides in calcium–aluminium-rich inclusions indicate that the Solar System must have been born near a source of the short-lived radionuclid...

Open AccessFaint objects in motion: the new frontier of high precision astrometry
Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint objects, a flexibly-pointed ins...

Observations of the IMF in Clusters
The Initial Mass Function (IMF) is a seemingly a universal outcome of the star formation process. Over the last five decades it has been measured in young clusters and associations, in old globulars and in the...

Mass segregation in young clusters: observational biases
We investigate the validity of the mass-segregation indicators most commonly used in the analysis of young stellar clusters. We construct and analyze synthetic massive clusters with a standard, fully sampled s...

EXTRAGALACTIC MOLECULAR CLOUDS
We report the results of our study of 436 giant molecular clouds (GMCs) in NGC5128 using dust extinction. The proposed technique allows us to probe the extinction up to 10 magnitudes in this galaxy. The clump ...

Map** Extragalactic Molecular Clouds: Centaurus a (NGC 5128)
We propose a novel albeit proven technique that uses dust extinction as a tracer of H2 to study the physical structure of a large sample of extragalactic GMCs.

Revealing the Structure of Lupine Darkness: from Cores to Clusters
We report in this paper results obtained from the analysis of deep near-infrared (NIR) observations of the densest region of the Lupus 3 cloud acquired from the European Southern Observatory's (ESO) New Techno...

Size Distribution of Disks in the Trapezium Cluster
In this paper we present preliminary results on the size distribution of proto-planetary (“proplyds”) disks in the Trapezium Cluster, as measured from HST/

Map** the Interstellar Dust with Near-Infrared Observations: An Optimized Multi-Band Technique
We generalize Lada et al. (1994) NICE technique to map dust column density through a molecular cloud to an optimized multi-band technique that can be applied to any multi-band survey of molecular clouds. We pr...

Molecular Cloud Structure: The VLT View
Despite 30 years of molecular spectroscopy of dark clouds little is understood about the internal structure of these objects and consequently about the initial conditions that give rise to star and planet form...

The Physical Structure of a Prestellar Core in IC 5146
We observed an evenly sampled map of the 3 P 1-3 P 0 line of neutral atomic carbon in a 0.5 × 0.5 pc2 quiescent, dark core regio...

Multiplicity of Young Brown Dwarfs in Cha I
How frequent are brown dwarf binaries? Do brown dwarfs have planets? Are current theoretical pre-main-sequence evolutionary tracks valid down to the substellar regime? - Any detection of a companion to a brown...

Direct Imaging and Spectroscopy of Substellar Companions Next to Young Nearby Stars in TWA
Direct imaging of substellar companions is possible since several years around nearby stars (e.g. Gl 229) and young stars (e.g. TWA-5). We are searching for brown dwarfs and giant planets as companions to star...
