Proof of polar ejection fom the close-binary core of the planetary nebula Abell 63
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…
Determination of the basic parameters of the dwarf nova EY Cygni
J. Echevarria, R. Michel, R. Costero +1
High-dispersion spectroscopy of EY Cyg obtained from data spanning twelve years show, for the first time, the radial velocity curves from both emission and absorption line systems,…
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.…
Discovery of a tight correlation among the prompt emission properties of long Gamma Ray Bursts
C. Firmani, G. Ghisellini, V. Avila-Reese +1
We report the discovery of a correlation among three prompt emission properties of GRBs. These are the isotropic peak luminosity L_iso, the peak energy of the time-integrated promp…
The Hubble diagram extended to z>>1: the gamma-ray properties of GRBs confirm the Lambda-CDM model
C. Firmani, V. Avila-Reese, G. Ghisellini +1
Tight constraints on cosmological parameters can be obtained with standard candles spanning a range of redshifts as large as possible. We propose to treat SN Ia and long Gamma-Ray…
