Summary[edit]
| Description |
Deutsch: Streuung der radialen Geschwindigkeitskomponente der Sterne in der galaktischen Scheibe in Abh. vom Abstand von der Rotationsachse auf Grundlage der Dichteverteilung nach McMillan P.J., Mass models of the Milky Way, in: Monthly Notices of the Royal Astronomical Society 414 S.2446ff, 2011 sowie des stellardynamischen Modells von Bottema R., Simulations of normal Spiral Galaxies, in: Monthly Notices of the Royal Astronomical Society Band 344, S.358 ff, 2003. Die aus dem Modell folgende Streuung ist im Verhältnis zur minimale Streuung gesetzt, welche für die Stabilität einer Sternscheibe erforderlich ist. Diese Untergrenze beruht auf Toomre A., On the gravitational Stability of a Disk of Stars, in: The Astrophysical Journal 139, S.1217 ff, 1964. |

Again I replaced as well the older galactic mass model by a more recent one. Instead of two curves for the scatter of the radial velocity i... |
