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.

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.File in questo prodotto:
