"Rotation curves" in self-consistent models of barred galaxies.

WOZNIAK H. and PFENNIGER D.

Abstract (from CDS):

We compare the "rotation curves" in self-consistent models of barred galaxies with the ones of SB0's. The models are constructed with Schwarzschild's method. The models reproduce the wavy pattern in the rotation curves observed in most SB0 galaxies. Depending on the local spatial mass fraction of retrograde orbits, the line-of-sight velocity is lowered or even negative. The local counter-rotation can be explained by retrograde orbits, without needing to invoke particular projection effects. Another result is that the model minimizing the absolute value of the total angular momentum is found to have a distribution function similar to N-body bar one.
