Masses of ejecta nebulae from LBVs (filled circles) and LBV candidates (open circles) as a function of the central star’s bolometric luminosity. Luminosities are taken from Smith et al. (2004), while masses are taken as follows: the Homunculus of η Car (Smith et al. 2003b), the Little Homunculus of η Car (Smith 2005), the Pistol star (Figer et al. 1999), IRAS 18576+0341/AFGL 2298 (Ueta et al. 2001), AG Car and Wra 751 (Voors et al. 2000), G79.29+0.46 (Higgs et al. 1994), Wray 17‐96 (Egan et al. 2002), Sher 25 (Brandner et al. 1997), P Cygni (Smith & Hartigan 2006), He 3‐519 (Smith et al. 1994), and the remaining values adopted from Clark et al. (2005). When masses are determined from measurements of dust masses, we assume a gas‐to‐dust mass ratio of 100. When uncertainties are not specified by authors, we adopt roughly ±25%. The lightly shaded part on the left side of the graph corresponds to luminosities of stars that may be post‐RSGs (see Smith et al. 2004).
