Abstract:
Using observations from the Herschel Inventory of The Agents of Galaxy
Evolution (HERITAGE) survey of the Magellanic Clouds (MC), we have
found 35 evolved stars and stellar end products that are bright in the
far-infrared. These 28 (LMC) and 7 (SMC) sources were selected from
the 529 evolved star candidates in the HERITAGE far-infrared point
source catalogs. Our source identification method is based on spectral
confirmation, spectral energy distribution characteristics, careful
examination of the multiwavelength images and includes constraints on
the luminosity, resulting in a thoroughly vetted list of evolved
stars. These sources span a wide range in luminosity and hence initial
mass. We found 13 low- to intermediate-mass evolved stars, including
asymptotic giant branch (AGB) stars, post-AGB stars, planetary
nebulae, and a symbiotic star. We also identify 10 high mass stars,
including 4 of the 15 known B[e] stars in the MC, 3 extreme red
supergiants that are highly enshrouded by dust, a Luminous Blue
Variable, a Wolf-Rayet star, and two supernova remnants. Further, we
report the detection of 9 probable evolved objects which were
previously undescribed in the literature. These sources are likely to
be among the dustiest evolved objects in the MC. The Herschel emission
may either be due to dust produced by the evolved star or it may arise
from swept-up interstellar medium material.
Description:
Far-IR and sub-mm observations of the MC were taken as part of the
HERITAGE Key Project (Meixner et al. 2013, J/AJ/146/62) using the
Photodetector Array Camera and Spectrometer (PACS) and the Spectral
and Photometric Imaging Receiver (SPIRE) on the Herschel Space
Observatory.
The optical UBVI and near-IR JHKs photometry comes from the Magellanic
Clouds Photometric Survey (MCPS; Zaritsky et al. 1997AJ....114.1002Z 1997AJ....114.1002Z);
the Infrared Survey Facility (IRSF) MC Point Source Survey (Kato et
al. 2007, II/288), the Two Micron All-Sky Survey (2MASS; Skrutskie et
al. 2006, VII/233), and the 2MASS 6X Deep Point Source Catalog
(6X2MASS; Cutri & 2MASS Team 2004, II/281). We also obtained
supplementary mid-IR data from the AKARI LMC point source catalog
(Kato et al. 2007, II/288; Ita et al. 2008PASJ...60S.435I 2008PASJ...60S.435I) and the
WISE all-sky catalog (Wright et al. 2010, II/311).

Note (2): Quality flag (as in Meixner+, 2013, J/AJ/146/62) as follows:
1 = sources that have a measured FWHM consistent with the FWHM of the PSF
(FWHMsource<1.1FWHMPSF). The flux for flux flag set to 1 sources is
therefore a robust accounting of the sources' brightnesses.
2 = FWHM determination failed, but the source has a S/N of greater than 5
3 = sources that have a measured FWHM greater than that of the PSF
(FWHMsource>1.1FWHMPSF)
4 = sources should be considered true sources with highly uncertain or
unknown fluxes
