On the incidence of eclipsing Am binary systems in the SuperWASP survey
arXiv:1402.7168 · doi:10.1051/0004-6361/201323158
Abstract
The results of a search for eclipsing Am star binaries using photometry from the SuperWASP survey are presented. The light curves of 1742 Am stars fainter than V = 8.0 were analysed for the presences of eclipses. A total of 70 stars were found to exhibit eclipses, with 66 having sufficient observations to enable orbital periods to be determined and 28 of which are newly identified eclipsing systems. Also presented are spectroscopic orbits for 5 of the systems. The number of systems and the period distribution is found to be consistent with that identified in previous radial velocity surveys of `classical' Am stars.
12 pages, 9 figures, 6 tables. Accepted for publication in A&A. Owing to large size, multi-page Figure 10 containing all 66 light curves is not included. Full version can be downloaded from http://www.astro.keele.ac.uk/~bs/Wasp_Am_Binary.pdf
