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.
Nested bars with different pattern speeds: NGC 2950

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.
