For a long time, WOH G64 was known as the most extreme red supergiant outside our Galaxy. However, in a matter of years it has faded, its pulsations have become suppressed and the…
Low- and high-velocity `water fountains': different evolutionary stages
Roldán A. Cala, Luis F. Miranda, José F. Gómez +1
`Water fountains' (WFs) are optically obscured evolved stars, most of them thought to be in the post-asymptotic giant branch (post-AGB) phase, characterized by HO maser emiss…
VLA survey of the 22 GHz H2O masers toward 10 silicate carbon stars
K. Ohnaka, D. A. Boboltz, G. Mulitz-Schimel +2
Despite their carbon-rich photospheres, silicate carbon stars show evidence of oxygen-rich circumstellar material, which is considered to exist in disks. Silicate carbon stars repr…
