dc.description.abstract | We present the analysis of the variability of the SPB-type star 53 Per based on space photometry from BRITE-Constellation nano-satellites and SMEI-Coriolis experiment. The two photometries allowed us to detect 17 independent sinusoidal terms in the range 0.2 - 1.4 d^{-1} plus one combination, and one harmonic. The independent terms can be attributed to g modes excited in this star. Only three of these modes have been known earlier. In addition, we gathered almost 3500 new mid- and high-resolution spectra of 53 Per, which were used to calculate radial velocities. The frequency spectrum of the time-series radial-velocity data revealed four independent terms and one combination, all consistent with the frequencies detected in BRITE and SMEI photometry. The high-resolution and high signal-to-noise averaged spectrum was used to obtain atmospheric parameters of 53 Per, T_eff = 15600 ± 400 K and log (g/(cm s^{-2}))= 3.85 ± 0.10. | en_US |
