Abstract:
Massive evolved stars lose a large fraction of their mass via copious
stellar wind or instant outbursts. During certain evolutionary phases,
they can be identified by the presence of their circumstellar nebulae.
In this paper, we present the results of a search for compact nebulae
(reminiscent of circumstellar nebulae around evolved massive stars)
using archival 24um data obtained with the Multiband Imaging
Photometer for Spitzer. We have discovered 115 nebulae, most of which
bear a striking resemblance to the circumstellar nebulae associated
with luminous blue variables (LBVs) and late WN-type (WNL)
Wolf-Rayet (WR) stars in the Milky Way and the Large Magellanic
Cloud (LMC).
