Abstract:
We present a clean, magnitude-limited (IRAC1 or WISE1≤15.0mag)
multiwavelength source catalog for the Large Magellanic Cloud (LMC).
The catalog was built by crossmatching (1'') and deblending (3'')
between the source list of Spitzer Enhanced Imaging Products (SEIP)
and Gaia Data Release 2 (DR2), with strict constraints on the Gaia
astrometric solution in order to remove the foreground contamination.
It is estimated that about 99.5% of the targets in our catalog are
most likely genuine members of the LMC. The catalog contains 197004
targets in 52 different bands, including two ultraviolet, 21 optical,
and 29 infrared bands. Additional information about radial velocities
and spectral and photometric classifications were collected from the
literature. We compare our sample with the sample from Gaia DR2
(2018A&A...616A...1G 2018A&A...616A...1G, Cat. I/345), indicating that the bright end of
our sample is mostly comprised of blue helium-burning stars (BHeBs)
and red HeBs with inevitable contamination of main sequence stars at
the blue end. After applying modified magnitude and color cuts based
on previous studies, we identified and ranked 2974 red supergiant,
508 yellow supergiant, and 4786 blue supergiant candidates in the LMC
in six color-magnitude diagrams (CMDs). The comparison between the
CMDs from the two catalogs of the LMC and Small Magellanic Cloud (SMC)
indicates that the most distinct difference appears at the bright red
end of the optical and near-infrared CMDs, where the cool evolved
stars (e.g., red supergiant stars (RSGs), asymptotic giant branch
stars, and red giant stars) are located, which is likely due to the
effect of metallicity and star formation history. A further
quantitative comparison of colors of massive star candidates in equal
absolute magnitude bins suggests that there is essentially no
difference for the BSG candidates, but a large discrepancy for the RSG
candidates since LMC targets are redder than the SMC ones, which may
be due to the combined effect of metallicity on both spectral type and
mass-loss rate as well as the age effect. The effective temperatures
(Teff) of massive star populations are also derived from
reddening-free color of (J-KS0. The Teff ranges are 3500<Teff<5000K
for an RSG population, 5000<Teff<8000K for a YSG population, and
Teff>8000K for a BSG population, with larger uncertainties toward the
hotter stars.
Description:
Catalogues of 197004 candidate members of the LMC derived from SEIP
source list and Gaia DR2, and 2974 RSG, 508 YSG, and 4786 BSG
candidates in the LMC identified by using modified color and magnitude
cuts based on previous studies. We provide positions, astrometry, and
photometry from several large-scale surveys (e.g., 52 different bands
of photometric data including two ultraviolet, 21 optical and 29
infrared bands from SEIP, VMC, IRSF, AKARI, HERITAGE, Gaia, SkyMapper,
NSC, Massey (2002ApJS..141...81M 2002ApJS..141...81M, Cat. II/236), OGLE, and GALEX.

Note (1): The candidates were ranked according to the intersections among all
available CMDs, for which those with the highest number (six) were given the
highest rank. 0 indicates that a target has been identified as the same type
of evolved massive star in all six datasets (Gaia, SkyMapper, NSC, M2002,
OGLE, and 2MASS) and so on (we note that there is no rank 0 target for
YSG candidates).
