Planetary nebulae in 2014: A review of research. (2015). Revista Mexicana De Astronomía Y Astrofísica, 51(2), 221. https://astronomia.unam.mx/journals/rmxaa/article/view/2015rmxaa..51..221z
Abstract
Planetary nebulae had a double anniversary in 2014, 250 years since their discovery and 150 years since the correct spectroscopic identification. This paper gives an overview of planetary nebula research published in 2014. Topics include surveys, central stars, abundances, morphologies, magnetic fields, stellar population and galactic dynamics. An important continuing controversy is the discrepancy between recombination-line and forbidden-line abundances. A new controversy is the relation between symbiotic stars and [WC] stars. PN of the year is undoubtedly CRL 618, with papers on its binary symbiotic/[WC] nucleus, rapid stellar evolution, expanding jets and magnetic fields.Similar Articles
