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…
MWC 297: a young high-mass star rotating at critical velocity
B. Acke, T. Verhoelst, M. E. van den Ancker +9
MWC 297 is a young massive nearby B[e] star. The central star has a large projected rotational velocity of 350 km/s. Despite the wealth of published observations, the nature of thi…
Probing the Early Evolution of Young High-Mass Stars
E. Puga, A. Bik, L. B. M. F. Waters +22
Near-infrared imaging surveys of high-mass star-forming regions reveal an amazingly complex interplay between star formation and the environment (Churchwell et al. 2006; Alvarez et…
The Structure of Protoplanetary Disks Surrounding Three Young Intermediate Mass Stars. I. Resolving the disk rotation in the [OI] 6300 Åline
G. van der Plas, M. E. van den Ancker, D. Fedele +4
We present high spectral resolution optical spectra of three young intermediate mass stars, in all of which we spectrally resolve the 6300 Angstrom [OI] emission line. Two of these…
