A Sea Change in Eta Carinae
arXiv:1004.3529 · doi:10.1088/2041-8205/717/1/L22
Abstract
Major stellar-wind emission features in the spectrum of Eta Car have recently decreased by factors of order 2 relative to the continuum. This is unprecedented in the modern observational record. The simplest, but unproven, explanation is a rapid decrease in the wind density.
