Abstract
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.
