All Tables

Table 1: Observing log of the time-resolved spectroscopic monitoring of HR 3831. Columns give the UT date, heliocentric Julian Date for the beginning and end of observation, the duration of continuous monitoring in hours, the range of rotation phases calculated according to the ephemeris of Kurtz et al. (1997), and the number of spectra obtained each night.
Table 2: Results of the non-linear least-squares fit of the Nd III 6145.07 Å line profile moment variations.
Table 3: Results of the non-linear least-squares fit of the RV variation of spectral lines other than Nd III 6145.07 Å.
Table 4: Parameters of the oblique pulsator model of HR 3831 determined from the variation of the Nd III 6145.07 Å line profile moments. This table reports stellar inclination i, angles $\delta$ and $\chi$ specifying orientation of the pulsation axis, and amplitudes (renormalised to yield the maximum surface velocity) of different spherical harmonic contributions to the pulsation velocity field.
