Abstract:
We report on a multi-site photometric campaign on the high-amplitude
delta Scuti star V2367 Cyg in order to determine the pulsation modes.
We also used high-dispersion spectroscopy to estimate the stellar
parameters and projected rotational velocity. Time series multi colour
photometry was obtained during a 98-d interval from five different
sites. These data were used together with model atmospheres and
non-adiabatic pulsation models to identify the spherical harmonic
degree of the three independent frequencies of highest amplitude as
well as the first two harmonics of the dominant mode. This was
accomplished by matching the observed relative light amplitudes and
phases in different wavebands with those computed by the models. In
general, our results support the assumed mode identifications in a
previous analysis of Kepler data.
