Outflows and Jets I: a personal take
Orsola De Marco
As a session chair I have the privilege to write down a few comments on four talks that were delivered under the general title of "outflows and jets I". This and the session that f…
The dual dust chemistry - binarity connection
Orsola De Marco, A. F. Jones, M. J. Barlow +1
Accumulating evidence points to a binary nature for the Wolf-Rayet ([WC]) central stars, a group that constitutes about 15% of all central stars of planetary nebula. From ISO obser…
Far-UV FUSE spectroscopy of the OVI resonance doublet in Sand2 (WO)
Paul A. Crowther, A. W. Fullerton, D. J. Hillier +10
We present Far-Ultraviolet Spectroscopic Explorer (FUSE) spectroscopy of Sand 2, a LMC WO-type Wolf-Rayet star, revealing the OVI resonance P Cygni doublet at 1032-38A. These data…
The gamma Velorum binary system. II. WR stellar parameters and the photon loss mechanism
Orsola De Marco, W. Schmutz, P. A. Crowther +4
In this paper we derive stellar parameters for the Wolf-Rayet star in the gamma Velorum binary system (WR11), from a detailed non-LTE model of its optical and infrared spectra. Com…
Wolf-Rayet nebulae as tracers of stellar ionizing fluxes: I. M1-67
P. A. Crowther, A. Pasquali, O. De Marco +3
We use WR124 (WN8h) and its associated nebula M1-67, to test theoretical non-LTE models for Wolf-Rayet (WR) stars. Lyman continuum ionizing flux distributions derived from a stella…
