Freshly ionized matter around the final Helium shell flash object V4334 Sgr (Sakurai's object)
F. Kerber, N. Pirzkal, Orsola De Marco +3
We report on the discovery of recently ionized hydrogen-deficient gas in the immediate circumstellar environment of the final helium shell flash star V4334 Sgr (Sakurai's object).…
Revised Stellar Temperatures for Magellanic Cloud O Supergiants from FUSE and VLT-UVES Spectroscopy
P. A. Crowther, D. J. Hillier, C. J. Evans +3
We have undertaken quantitative analysis of four LMC and SMC O4--9.7 extreme supergiants using far-ultraviolet FUSE, ultraviolet IUE/HSTand optical VLT UVES spectroscopy. Extended,…
Discovery of an edge-on dust disk around the [WC10] central star CPD-568032
Orsola De Marco, M. J. Barlow, M. Cohen
We present Hubble Space Telescope ultraviolet and optical STIS spectroscopy of the [WCL] planetary nebula central star CPD-568032, obtained during its latest lightcurve minimum. Th…
A New Look at the Evolution of Wolf-Rayet Central Stars of Planetary Nebulae
Orsola De Marco, Noam Soker
We construct a speculative scenario for the evolution of Wolf-Rayet central stars of planetary nebula. It is clear from the latest infra-red observations that a new perspective has…
What are the Hot R Coronae Borealis Stars?
Orsola De Marco, Geoffrey C. Clayton, F. Herwig +3
We investigate the evolutionary status of four stars: V348 Sgr, DY Cen and MV Sgr in the Galaxy and HV 2671 in the LMC. These stars have in common random deep declines in visual br…
