摘要
A new sdOB variable star, J23341+4622 (SDSS J233406.10+462249.3), was discovered during photometric observations with the Nordic Optical Telescope (La Palma). We found its main pulsation frequency at 7422 (+/- 9), mu Hz with an amplitude of 4.5 (+/- 0.5) mma. The star is possibly a complex pulsator, as we found another significant peak at 7759 (+/- 11) mu Hz with an amplitude of 2.0 (+/- 0.3) mma and a possible subharmonic of the main frequency at 3508 mu Hz with an amplitude of 2.3 mma.
