A planetary nebula around nova V458 Vul undergoing flash ionization
R. Wesson, M. J. Barlow, R. L. M. Corradi +25
Nova V458 Vul erupted on 2007 August 8th and reached a visual magnitude of 8.1 a few days later. H images obtained six weeks before the outburst as part of the IPHAS galactic pl…
The hydrogen-deficient knot of the `born again' planetary nebula Abell 58 (V605 Aql)
R. Wesson, M. J. Barlow, X-W. Liu +3
We have analysed deep optical spectra of the `born-again' planetary nebula Abell 58 and its hydrogen-deficient knot, surrounding V605 Aql, which underwent a nova-like eruption in 1…
Observations and 3D photoionisation modelling of the Wolf-Rayet planetary nebula NGC 1501
Barbara Ercolano, R. Wesson, Y. Zhang +4
Deep optical spectra of the high excitation planetary nebula NGC 1501 and its W04 central star are presented. A recombination line abundance analysis of the central star's emission…
Discovery of a WO star in the Scutum-Crux arm of the inner Galaxy
Janet E. Drew, M. J. Barlow, Y. C. Unruh +5
We report the discovery of only the fourth massive WO star to be found in the Milky Way, and only the seventh identified within the Local Group. This has resulted from the first ob…
Electron temperatures and densities of planetary nebulae determined from the nebular hydrogen recombination spectrum and temperature and density variations
Y. Zhang, X. -W. Liu, R. Wesson +3
A method is presented to derive electron temperatures and densities of planetary nebulae (PNe) simultaneously, using the observed hydrogen recombination spectrum, which includes co…
Physical conditions in the planetary nebula Abell 30
R. Wesson, X-W. Liu, M. J. Barlow
We have analysed optical spectra of two of the hydrogen-deficient knots (J1 & J3) in the born-again planetary nebula Abell 30, together with UV spectra of knots J3 & J4. We determi…
