Baseline observations of the medium amplitude delta Scuti V873 Herculis.

HINTZ E.G. and SCHOONMAKER J.N.

Abstract (from CDS):

The Scuti variable V873 Herculis has previously been studied only once as a variable star, and with a small data set. However, its position in the amplitude range between the high-amplitude Scuti and the more common low-amplitude Scuti makes it an important target for more extensive studies. From 24 nights of photometric data, we determined a new period of 0.12716809 d. We also found a rich frequency spectrum from a multiple-frequency analysis with two dominant frequencies at and. From three nights of spectroscopic observations, we found a rotational velocity of and an average radial velocity of. We find V873 Her to be an ideal candidate for a multisite asteroseismology campaign.
