High Resolution Spectra of Novae and the Quadratic Zeeman Effect. (2006). Revista Mexicana De Astrofísica Y Astronomía Serie De Conferencias, 26, 33-36. https://doi.org/10.22201/ia.14052059p.2006.26.12
Abstract
High resolution spectra of novae after outburst reveal distinctive characteristics in the line profiles and intensities. The higher Balmer lines are often broader than the lower members of the series, and the relative profiles and intensities of the [O I] λλ 6300, 6364 doublet differ from normal values. We suggest these features may be caused by the Quadratic Zeeman Effect from magnetic fields exceeding B=10^6 gauss. Taken together the emission and absorption lines point to multiple origins for the ejecta on both the erupting white dwarf and the cool secondary star.Similar Articles
