On the mass segregation of stars and brown dwarfs in Taurus.

Abstract (from CDS):
We find that the most massive stars in Taurus are inversely mass segregated with ΛMSR= 0.70±0.10 (ΛMSR= 1 corresponds to no mass segregation), which differs from the strong mass segregation signatures found in more dense and massive clusters such as Orion. The brown dwarfs in Taurus are not mass segregated, although we find evidence that some low-mass stars are, with an ΛMSR= 1.25 ±0.15. Finally, we compare our results to previous measures of the spatial distribution of stars and brown dwarfs in Taurus, and briefly discuss their implications.
