Optical and UV surface brightness of translucent dark nebulae: Dust albedo, radiation field and fluorescence emission by H2
K. Mattila, M. Haas, L. K. Haikala +4
Photometry of the nebulae LDN1780, LDN1642 and LBN406 is used to derive scattering properties of dust and to investigate the presence of UV fluorescence emission by molecular hydro…
Mid-Infrared Spectral Variability Atlas of Young Stellar Objects
Á. Kóspál, P. Ábrahám, J. A. Acosta-Pulido +6
Optical and near-infrared variability is a well-known property of young stellar objects. However, a growing number of recent studies claim that a considerable fraction of them also…
First AU-scale observations of V1647 Ori with VLTI/MIDI
P. Abraham, L. Mosoni, Th. Henning +4
The young eruptive star V1647 Ori was observed with MIDI, the mid-infrared interferometric instrument at the Very Large Telescope Interferometer (VLTI), on March 2, 2005. We presen…
First VLTI/MIDI observations of a Be star: Alpha Ara
Olivier Chesneau, A. Meilland, T. Rivinius +12
We present the first VLTI/MIDI observations of the Be star Alpha Ara, showing a nearly unresolved circumstellar disk in the N band. The interferometric measurements made use of the…
Evidence for grain growth in T Tauri disks
F. Przygodda, R. van Boekel, P. Àbrahàm +3
In this article we present the results from mid-infrared spectroscopy of a sample of 14 T Tauri stars with silicate emission. The qualitative analysis of the spectra reveals a corr…
