A Multiwavelength Survey of Wolf-Rayet Nebulae in the Large Magellanic
  Cloud
  Surveys of Wolf-Rayet (WR) stars in the Large Magellanic Cloud (LMC) have
yielded a fairly complete catalog of 154 known stars. We have conducted a
comprehensive, multiwavelength study of the interstellar/circumstellar
environments of WR stars, using the Magellanic Cloud Emission Line Survey
(MCELS) images in the H$\alpha$, [O III], and [S II] lines; Spitzer Space
Telescope 8 and 24 $\mu$m images; Blanco 4m Telescope H$\alpha$ CCD images; and
Australian Telescope Compact Array (ATCA) + Parkes Telescope H I data cube of
the LMC. We have also examined whether the WR stars are in OB associations,
classified the H II environments of WR stars, and used this information to
qualitatively assess the WR stars' evolutionary stages. The 30 Dor giant H II
region has active star formation and hosts young massive clusters, thus we have
made statistical analyses for 30 Dor and the rest of the LMC both separately
and altogether. Due to the presence of massive young clusters, the WR
population in 30 Dor is quite different from that from elsewhere in the LMC. We
find small bubbles ($<$50 pc diameter) around $\sim$12% of WR stars in the LMC,
most of which are WN stars and not in OB associations. The scarcity of small WR
bubbles is discussed. Spectroscopic analyses of abundances are needed to
determine whether the small WR bubbles contain interstellar medium or
circumstellar medium. Implications of the statistics of interstellar
environments and OB associations around WR stars are discussed. Multiwavelength
images of each LMC WR star are presented.
