Abstract (from CDS):

We present a total of 57 days of contiguous, high-cadence photometry (14 days in 2004 and 43 in 2005) of the star BD+18 4914 obtained with the MOST1 satellite. We detect 16 frequencies down to a signal-to-noise of 3.6 (amplitude 0.5 mmag). Six of these are less than 3 cycles/day, and the other ten are between 7 and 16 cycles/day. We intrepret the low frequencies as g-mode γ Doradus-type pulsations and the others as δ Scuti-type p-modes, making BD+18 4914 one of the few known hybrid pulsators of its class. If the g-mode pulsations are high-overtone non-radial modes with identical low degree, we can assign a unique mode classification of n={12, 20, 21, 22, 31, 38} based on the frequency ratio method.
