C. Porcel et E. Battaner, THE WARPED DISTRIBUTION OF YOUNG STARS IN THE SOUTHERN MILKY-WAY, Monthly Notices of the Royal Astronomical Society, 274(4), 1995, pp. 1153-1156
From a sample presented by Reed containing OB stars with a heliocentri
c distance greater than 5 kpc, we have selected those stars with a gal
actocentric azimuth between 240 degrees and 275 degrees, i.e. in the r
egion of the maximum warp in the southern hemisphere. Only nine stars
have these characteristics, but they permit a first, unambiguous detec
tion of the southern stellar warp in the Milky Way. This seems to be a
s large as the gaseous warp, and does not present evidence of twisting
of the line of nodes. Flaring of the stellar distribution with respec
t to the centroid of the HI warp is also noticeable.
