Comprehensive modelling of the planetary nebula LMC-SMP 61 and its [WC]-type central star
G. Stasińska, G. Gräfener, M. Peña +3
We present a comprehensive study of the Magellanic Cloud planetary nebula SMP 61 and of its nucleus, a Wolf-Rayet type star classified [WC 5-6]. We have performed a detailed spectr…
The Conspicuous Absence of X-ray Emission from Carbon-Enriched Wolf-Rayet Stars
L. M. Oskinova, R. Ignace, W. -R. Hamann +2
The carbon-rich WC5 star WR 114 was not detected during a 15.9 ksec XMM-Newton observation, implying an upper limit to the X-ray luminosity of Lx < 2.5*10^{30} erg/s and to the X-r…
X-ray line emission from a fragmented stellar wind
Achim Feldmeier, Lida Oskinova, Wolf-Rainer Hamann
We discuss X-ray line formation in dense O star winds. A random distribution of wind shocks is assumed to emit X-rays that are partially absorbed by cooler wind gas. The cool gas r…
