Abstract:
A survey for A-F type supergiants in the Large Magellanic Cloud has
been carried out using UV objective prism plates. 890 objects were
detected and their spectral types, luminosity classes, magnitudes, and
precise positions determined. The survey is practically complete to
mpg=12.5 and extends for certain types of stars to mpg=14. It is
found that the spatial distribution of the A-F supergiants is not
correlated with the distribution of the gas and OB stars of the cloud.
This is evidence in support of the tentative identification by Stock
and Wroblewski of early-type galactic supergiants well off the plane.
Several other implications of this result are also discussed.
