First evidence for a spatially resolved disk structure around the Herbig Ae star R CrA
S. Correia, R. Koehler, G. Meeus +1
We present mid-infrared interferometric observations of the Herbig Ae star R CrA obtained with MIDI at the VLTI using several projected baselines in the UT2-UT3 configuration. The…
A deep look into the cores of young clusters I. sigma-Orionis
H. Bouy, N. Huelamo, E. L. Martin +9
Nearby young clusters are privileged places to study the star formation history. Over the last decade, the sigma-Orionis cluster has been a prime location for the study of young ve…
First determination of the dynamical mass of a binary L dwarf
H. Bouy, G. Duchene, R. Koehler +11
We present here the results of astrometric, photometric and spectroscopic observations leading to the determination of the orbit and dynamical masses of the binary L dwarf 2MASSW J…
Stellar and circumstellar properties of visual binaries in the Orion Nebula Cluster
S. Correia, G. Duchene, B. Reipurth +8
Our general understanding of multiple star and planet formation is primarily based on observations of young multiple systems in low density regions like Tau-Aur and Oph. Since many…
Orbital motion in T Tauri binary systems
J. Woitas, R. Koehler, Ch. Leinert
Using speckle-interferometry we have carried out repeated measurements of relative positions for the components of 34 T Tauri binary systems. The projected separation of these comp…
Discovery of a close companion to the young star Haro 6-37
A. Richichi, R. Koehler, J. Woitas +1
We report lunar occultation (LO) and speckle interferometry observations of Haro 6-37, all carried out at lambda=2.2 microns. The main finding is the discovery of a new close compa…
