“…Strohmeier et al (1962) derived its eclipsing behavior with a orbital period of 0.51 d and classified it as an Algol (EA) type eclipsing binary. Later, the photoelectric observations were obtained by Williamon (1974), Padalia (1979) and Covino et al (1988). Williamon (1974) who showed the light curves to be more like that of β Lyrae (EB) type with a period of 0.5089951 d and analyzed these using the method of Russell & Merrill (1952).…”

“…Russo & Sollazzo (1982) found many inconsistencies in applying the Russell and Merrill (1952) method of solution. Therefore they reanalyzed both V light curves of Williamon (1974) and Padalia (1979) using the Wilson & Devinney (1971) model. They obtained the same results for both light curves while the Russell-Merrill model does not.…”

We study the radial-velocity and light curves of the two eclipsing binaries EE Aqr and Z V ul. Using the latest version of the Wilson & Van Hamme (2003) model, absolute parameters for the systems are determined. We find that EE Aqr and Z V ul are nearcontact and semi-detached systems, respectively. The primary component of EE Aqr fills about 96% of its 'Roche lobe', while its secondary one appears close to completely filling this limiting volume. In a similar way, we find fill-out proportions of about 72 and 100% of these volumes for the primary and secondary components of Z V ul respectively. We compare our results with those of previous authors.

Eclipsing binaries in the MOST satellite fields

et al. 2010

View full text Add to dashboard Cite

Sixteen new eclipsing binaries have been discovered by the MOST satellite among guide stars used to point its telescope in various fields. Several previously known eclipsing binaries were also observed by MOST with unprecedented quality. Among the objects we discuss in more detail are short-period eclipsing binaries with eccentric orbits in young open clusters: V578 Mon in NGC 2244 and HD 47934 in NGC 2264. Long nearly-continuous photometric runs made it possible to discover three long-period eclipsing binaries with orbits seen almost edge-on: HD 45972 with P = 28.1 days and two systems (GSC 154 1247 and GSC 2141 526) with P > 25 days. The high precision of the satellite data led to discoveries of binaries with very shallow eclipses (e.g., HD 46180 with A = 0.016 mag, and HD 47934 with A = 0.025 mag). Ground-based spectroscopy to support the space-based photometry was used to refine the models of several of the systems.
