The Astrophysical JournalThe physics of recombination lines in the He i singlet system is expected to be relatively simple, supported by accurate atomic models. We examine the intensities of He i singlets λ 3614, λ 3965, λ 5016, λ 6678, and λ 7281 and the triplet He i λ 5876

Planetary nebulae : getting closer to an unbiased binary fraction
, 2012 Why 80% of planetary nebulae are not spherical is not yet understood. The Binary Hypothesis states that a companion to the progenitor of the central star of a planetary nebula is required to shape the nebula and even for a planetary nebula to be formed ...
