A Photometric Catalogue of Southern Emission-Line Stars
D. de Winter, M. E. van den Ancker, A. Maira +5
We present a catalogue of previously unpublished optical and infrared photometry for a sample of 162 emission-line objects and shell stars visible from the southern hemisphere. The…
H2 and CO emission from disks around TTauri and HerbigAe pre-main-sequence stars and from debris disks around young stars: warm and cold circumstellar gas
W. F. Thi, E. F. van Dishoeck, G. A. Blake +8
We present ISO-SWS observations of H2 pure-rotational line emission from the disks around low and intermediate mass pre-main-sequence stars as well as from young stars thought to b…
The Stellar Composition of the Star Formation Region CMa R1. II. Spectroscopic and Photometric Observations of 9 Young Stars
H. R. E. Tjin A Djie, M. E. van den Ancker, P. F. C. Blondel +4
We present new high and low resolution spectroscopic and photometric data of nine members of the young association CMa R1. All the stars have circumstellar dust at some distance as…
The composition of circumstellar gas and dust in 51 Oph
M. E. van den Ancker, G. Meeus, J. Cami +2
We analyze ISO archive data of the nearby bright emission-line star 51 Oph, previously classified as a proto-planetary system similar to beta Pic. The infrared spectrum reveals the…
