Scientific paper

The radial velocity dispersion is determined for a sample of late M stars in the nuclear bulge of the Galaxy. Although these stars are chemically among the youngest in the spheroidal subsystem and may be physically younger by a few billion years, they have a velocity dispersion of 113 ± 11 km s-1, similar to that of the oldest objects in the halo.
