We present an analysis of three new pulsating subdwarf B stars discovered in the SuperWASP archive .
Two of the stars , J1938+5609 and J0902–0720 , are p-mode pulsators ; J1938+5609 shows a pulsation at 231.62 d ^ { -1 } ( P = 373 s ; 2681 \mu Hz ) with an amplitude of 4 mmag , whereas J0902–0720 pulsates at frequencies 636.74 d ^ { -1 } ( P = 136 s ; 7370 \mu Hz ) and 615.34 d ^ { -1 } ( P = 140 s ; 7122 \mu Hz ) , with amplitudes 7.27 and 1.53 mmag , respectively .
The third star , J2344–3427 , is a hybrid pulsator with a p-mode frequency at 223.16 d ^ { -1 } ( P = 387 s ; 2583 \mu Hz ) and a corresponding amplitude of 1.5 mmag , and g modes in the frequency range 8.68 - 28.56 d ^ { -1 } ( P = 3025 - 9954 s ; 100 - 331 \mu Hz ) and amplitudes between 0.76 and 1.17 mmag .
Spectroscopic results place J1938+5609 and J2344–3427 among the long-period or hybrid pulsators , suggesting there may be further modes in these stars below our detection limits , with J0902–0720 placed firmly amongst the p-mode pulsators .
