Abstract:
RU Eri is a near-contact eclipsing binary (V∼9.24mag) with a
0.632-day orbital period. The Wilson-Devinney program is used to
simultaneously solve new UBV light curves obtained between 1973 and
1981 at the Fernbank Science Center Observatory, together with
existing single-lined radial velocity measurements. Light and velocity
solution parameters, orbital elements, and absolute dimensions are
presented. A period of 0.632198836±0.000000046d is found.
Description:
The photometric measurements of RU Eri (HD 24658, BD-15 686,
SAO 149243) were obtained with the 90-cm Cassegrain reflector at the
Fernbank Science Center (Atlanta, GA) between 1973 and 1981. More than
570 observations were made in each of the U, B and V bands with an
unrefrigerated EMI 6256s photomultiplier.
