Nested Bars with Different Pattern Speeds: NGC 2950

  • 70 Accesses

Part of the ESO Astrophysics Symposia book series (ESO)

Abstract

We studied the SB0 galaxy NGC 2950, which hosts two nested stellar bars. We used the Tremaine-Weinberg method to measure the pattern speed of the primary bar. We established directly and for the first time in a double-barred galaxy that the two nested bars are rotating with different pattern speeds.
