In February - March 2004, the WIRE satellite observed Lambda Sco and 57 Eri, two early B subgiant stars. Lambda Sco is a known β Cepheid and spectroscopic binary (Uytterhoeven et al. 2004), while 57 Eri has been previously reported only as a spectroscopic binary. The WIRE light curves, which are characterized by white noise levels more than an order of magnitude less than those obtained from ground-based sources, show clearly that both stars are multimodal β Cepheids. In this paper, we present data and preliminary analysis of the modal structure of the oscillations for both stars.
In addition, for each star we detect 3 eclipses, which have never before been seen in these (previously) spectroscopic binaries. We use data from the eclipses to refine fundamental orbital parameters for these systems.
