Evidence for CO depletion in the inner regions of gas-rich protoplanetary disks
G. van der Plas, M. E. van den Ancker, B. Acke +4
We investigate the physical properties and spatial distribution of Carbon Monoxide (CO) gas in the disks around the Herbig Ae/Be stars HD 97048 and HD 100546. Using high-spectral-r…
The structure of the protoplanetary disk surrounding three young intermediate mass stars. II. Spatially resolved dust and gas distribution
D. Fedele, M. E. van den Ancker, B. Acke +7
[Abridged] We present the first direct comparison of the distribution of the gas, as traced by the [OI] 6300 AA emission, and the dust, as traced by the 10 micron emission, in the…
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We present a catalogue of previously unpublished optical and infrared photometry for a sample of 162 emission-line objects and shell stars visible from the southern hemisphere.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…
ISO spectroscopy of circumstellar dust in 14 Herbig Ae/Be systems: towards an understanding of dust processing
G. Meeus, L. B. F. M. Waters, J. Bouwman +3
We present Infrared Space Observatory (ISO) spectra of fourteen isolated Herbig Ae/Be (HAEBE) stars, to study the characteristics of their circumstellar dust. These spectra show la…
ISO Spectroscopy of the Young Bipolar Nebulae S106 IR and Cep A East
M. E van den Ancker, A. G. G. M. Tielens, P. R Wesselius
We present the results of ISO SWS and LWS grating scans towards the embedded Young Stellar Objects (YSOs) S106 IR and Cep A East. Emission from the pure rotational lines of H2 and…
On the nature of XTE J0421+560/CI Cam
T. Belloni, S. Dieters, M. E. van den Ancker +7
We present the results of the analysis of RXTE, BATSE and optical/infrared data of the 1998 outburst of the X-ray transient system XTE J0421+560 (CI Cam). The X-ray outburst shows…
