In search of binary Wolf-Rayet central stars of planetary nebulae
Includes bibliographical references. === Planetary Nebulae (PNe) are circumstellar gas envelopes ejected during Asymptotic Giant Branch (AGB) phase of the stars between 1M࿉ to 8M࿉. In around 3000 galactic PNe, 10 to 20 % are known to host a Wolf-Rayet type central star ([WR] CSPN). These [WR] CSPNe...
