Results are presented from a multisite photometric campaign on the pulsating subdwarf B star, PG 1047+003. Approximately 98 h of data were obtained from three sites, with a duty cycle of ∼30 per cent. The light curve of PG 1047+003 is dominated by several frequencies in the range ∼6880–7500 μHz (periods 133–145 s). We identify, with some confidence, 18 frequencies between 5700 and 9605 μHz (104–175 s) down to an amplitude of 0.0004 in fractional intensity (0.04 per cent), thus doubling the number of published pulsation frequencies for this star. These pulsations correspond to low-order and low-degree acoustic modes. Several frequency spacings near 1.05 μHz suggest a rotation period for the star of 11.0 d. [ABSTRACT FROM AUTHOR] |
