Variable accretion as a mechanism for brightness variations in T Tau S
Roy van Boekel, Attila Juhasz, Thomas Henning +5
(Note: this is a shortened version of the original A&A-style structured abstract). The physical nature of the strong photometric variability of T Tau Sa, the more massive member of…
A deep look into the core of young clusters. II. lambda-Orionis
H. Bouy, N. Huelamo, D. Barrado y Navascues +14
Over the past years, the lambda-Orionis cluster has been a prime location for the study of young very low mass stars, substellar and isolated planetary mass objects and the determi…
Kelu-1 AB - A possible brown dwarf triple system
M. B. Stumpf, W. Brandner, Th. Henning +5
We have monitored the benchmark L dwarf binary Kelu-1AB over the past 3 years to derive improved spectral types and luminosities for the individual components. The astrometric meas…
Binary Stars in the Orion Nebula Cluster
Rainer Koehler, Monika G. Petr-Gotzens, Mark J. McCaughrean +4
We report on a high-spatial-resolution survey for binary stars in the periphery of the Orion Nebula Cluster, at 5 - 15 arcmin (0.65 - 2 pc) from the cluster center. We observed 228…
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 Multiplicity Survey of the Rho Ophiuchi Molecular Clouds
Thorsten Ratzka, Rainer Koehler, Christoph Leinert
We present a volume-limited multiplicity survey with magnitude cutoff (K =< 10.5 mag) of 158 young stellar objects located within or in the vicinity of the Rho Ophiuchi Dark Cloud.…
