NET Angular Momentum of Globular cluster of stars

Is the NET angular momentum of a globular cluster of stars, zero? e.g. Omega Centauri or M13 for example. Is the NET angular momentum of an elliptical galaxy and or the central bulge of a spiral, zero or close to zero..........oblate spheroids might have a net angular momentum if the oblate geometry is due to rotation in a single direction. But if it's due to net rotation 50 / 50 in two opposite directions, again, there would be no net angular momentum, right? rt The paper: https://arxiv.org/abs/1704.02005 provides some interesting insight and more questions as to this general problem. In as much as hydrogen alpha is an indicator of the Milky Way galactic halo, it remains fixed relative to the galaxy rotating within. RDS |
