The spectroscopic variability of T${}_{\mathrm{eff}}$ and $\log g$ in $\beta$ Cep

G. Catanzaro, F. Leone

Time resolved spectra of $\beta$ Cep yield the following average results: T${}_{\mathrm{eff}}$ =24000 $\pm$ 250 K, $\log g$ = 3.91 $\pm$ 0.05 and $\xi$ = 8.1 $\pm$ 0.9 km s${}^{-1}$. N, O, Ne, Al…
