Abstract
In this paper, we report our preliminary results regarding the asteroseismic modeling of the slow pulsating B star HD 163830, based on eighteen of the twenty detected frequencies of this star. The powerful method of matching stellar models both to oscillation data and eective temperature and gravity of HD 163830 is applied to identify a best-t model. These eighteen frequencies correspond to low-order, high-degree g-modes of an stellar model of 1:016 10 8 yr, of a 4:4M star with chemical composition X = 0:71, Z = 0:02.
