Direct detection of exo-planets: GQ Lupi
Ralph Neuhaeuser, Eike Guenther, Peter Hauschildt
We present a comparison of our VLT/NACO K-band spectrum of the GQ Lupi companion with the new GAIA-dusty model atmosphere grid for T=2000 and 2900 K and log g from 0 to 4. Then, we…
Late-epoch optical and near-infrared observations of the GRB000911 afterglow and its host galaxy
N. Masetti, E. Palazzi, E. Pian +28
We present the results of an optical and near-infrared (NIR) monitoring campaign of the counterpart of Gamma-Ray Burst (GRB) 000911, located at redshift z=1.06, from 5 days to more…
Submillimetre continuum emission from Class 0 sources: Theory, Observations, and Modelling
Miriam Rengel, Klaus Hodapp, Dirk Froebrich +2
We report on a study of the thermal dust emission of the circumstellar envelopes of a sample of Class 0 sources. The physical structure (geometry, radial intensity profile, spatial…
Near-IR observations of UCHII regions
Carlos Alvarez, Markus Feldt, Thomas Henning +3
We present adaptive-optics (AO) assisted J, H and K/K' images of 8 UCHII regions taken with the ALFA and ADONIS AO systems at Calar Alto and La Silla observatories. The images show…
Rotation periods for very low mass stars in the Pleiades
Alexander Scholz, Jochen Eisloeffel
We present the results of a photometric monitoring campaign for very low mass (VLM) members of the Pleiades. Periodic photometric variability was detected for nine VLM stars with m…
Rotation and accretion of very low mass objects in the SigmaOri cluster
Alexander Scholz, Jochen Eisloeffel
We report on two photometric monitoring campaigns of Very Low Mass (VLM) objects in the young open cluster around SigmaOrionis. Our targets were pre-selected with multi-filter phot…
