Fig. 5


HR diagram showing the position of IRAS 1835−06 and the post-RSG candidates RSGC1-15 and Ste2-49 (Davies et al. 2007a, 2008) assuming a distance of ~6 kpc. We conservatively adopt 8000 K < T < 10 000 K for IRAS 1835−06 (appropriate for an A hypergiant). We also plot the evolutionary tracks of Georgy (2012) and Groh et al. (2013b) with the positions of the resultant SNe indicated by coloured dots. The 18 M and 20 M tracks (green and purple respectively) assume the standard mass loss rate prescription of Ekström et al. (2012), the 15 M tracks 5 × and 10 × standard (dark and light blue respectively) and the 12 M track assumes a mass loss rate 10 × standard (red).
