AKARI/IRC observations of heavily obscured oxygen-rich AGB and post-AGB stars

, 2009
We present AKARI/IRC observations of a sample of six extremely red IRAS sources, of which three are variable OH/IR stars and the rest are early post-AGB stars. The OH/IR stars show a red continuum with the expected strong 10 micron silicate absorption feature, while the post-AGB stars show an even redder continuum accompanied with a comparably weak ...

Interferometric studies of AGB and post-AGB stars

, 2013
Several classes of evolved stars contain highly luminous objects, which, more often than not, are characterized by strong mass loss. Two fundamental properties that lie at the basis of their outer appearance and internal evolution, as well as that of the galaxies in which they are embedded.
