Abstract:
We present a catalog of 1750 massive stars in the Large Magellanic
Cloud (LMC), with accurate spectral types compiled from the
literature, and a photometric catalog for a subset of 1268 of these
stars, with the goal of exploring their infrared properties. The
photometric catalog consists of stars with infrared counterparts in
the Spitzer SAGE survey database, for which we present uniform
photometry from 0.3 to 24um in the UBVIJHKs+IRAC+MIPS24 bands. The
resulting infrared color-magnitude diagrams illustrate that the
supergiant B[e], red supergiant, and luminous blue variable (LBV)
stars are among the brightest infrared point sources in the LMC, due
to their intrinsic brightness, and at longer wavelengths, due to dust.
We detect infrared excesses due to free-free emission among ∼900 OB
stars, which correlate with luminosity class. We confirm the presence
of dust around 10 supergiant B[e] stars, finding the shape of their
spectral energy distributions (SEDs) to be very similar, in contrast
to the variety of SED shapes among the spectrally variable LBVs. The
similar luminosities of B[e] supergiants (log L/L☉≥4) and the
rare, dusty progenitors of the new class of optical transients (e.g.,
SN 2008S and NGC 300 OT), plus the fact that dust is present in both
types of objects, suggests a common origin for them. We find the
infrared colors for Wolf-Rayet stars to be independent of spectral
type and their SEDs to be flatter than what models predict.
