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…
Star cluster kinematics with AAOmega
L. L. Kiss, Z. Balog, Gy. M. Szabo +2
The high-resolution setup of the AAOmega spectrograph on the Anglo-Australian Telescope makes it a beautiful radial velocity machine, with which one can measure velocities of up to…
AAOmega radial velocities rule out current membership of the planetary nebula NGC 2438 in the open cluster M46
L. L. Kiss, Gy. M. Szabo, Z. Balog +2
We present new radial velocity measurements of 586 stars in a one-degree field centered on the open cluster M46, and the planetary nebula NGC 2438 located within a nuclear radius o…
MASH-II: More Planetary Nebulae from the AAO/UKST HαSurvey
B. Miszalski, Q. A. Parker, A. Acker +3
We present a supplement to the Macquarie/AAO/Strasbourg H planetary nebulae (PNe) catalogue (MASH), which we denote MASH-II. The supplement consists of over 300 true, likely and…
Multi-wavelength study of a new Galactic SNR G332.5-5.6
M. Stupar, Q. A. Parker, M. D. Filipovic +3
We present compelling evidence for confirmation of a Galactic supernova remnant (SNR) candidate, G332.5-5.6, based initially on identification of new, filamentary, optical emission…
Spitzer IRAC observations of newly-discovered planetary nebulae from the Macquarie-AAO-Strasbourg H-alpha Planetary Nebula Project
Martin Cohen, Quentin A. Parker, Anne J. Green +10
We compare H-alpha, radio continuum, and Spitzer Space Telescope (SST) images of 58 planetary nebulae (PNe) recently discovered by the Macquarie-AAO-Strasbo- urg H-alpha PN Project…
