Deborah L. Mitchell, Don Pollacco, T. J. O'Brien +4
We present the first detailed kinematical analysis of the planetary nebula Abell 63, which is known to contain the eclipsing close-binary nucleus UU Sge. Abell 63 provides an impor…
Dense Matter in Compact Stars: Theoretical Developments and Observational Constraints
Dany Page, Sanjay Reddy
We review theoretical developments in studies of dense matter and its phase structure of relevance to compact stars. Observational data on compact stars, which can constrain the pr…
New Planerary Nebulae towards the Galactic bulge
P. Boumis, S. Akras, P. A. M. van Hoof +3
New Planetary Nebulae (PNe) were discovered through an [O III] 5007 A emission line survey in the Galactic bulge region with l>0 deg. We detected 240 objects, including 44 new PNe.…
