A New Outburst of the Yellow Hypergiant Star ρ Cas
Abstract
Spectroscopic monitoring of the yellow hypergiant ρ Cas revealed a new outburst in 2013, which is obvious from the development of TiO bands in the spectra. Also many atmospheric lines characteristic of a later spectral type appear. This spectroscopic outburst is in agreement with the photometric light curve, which displays a drop by about 0.6 mag during the same period.
