Description
135 h of observations of HR 3831 obtained in 1981 have been reanalysed together with 43 hr of new observations obtained in 1985 which are presented in this paper. From the relationship between the phase of the principal 1.42801-mHz oscillation and the rotational phase of HR 3831 (determined from the magnetic field and mean light variations) it is demonstrated that this principal oscillation is essentially due to a long-lived oblique dipole pulsation mode. It is also shown that there is a slight, but significant, difference in the oscillation phase diagram between the 1981 and 1985 data sets. (author)
