W UMa (W Ursae Majoris) is the prototype of a class of contact binary variable stars.
The W Ursae Majoris stars are close binary stars, whose surfaces are in contact with one another.
A-type W UMa binaries are composed of two stars both hotter than the Sun, having spectral types A or F, and periods of 0.4 to 0.8 days.

 2.6 W UMa stars
W UMa stars are eclipsing binaries with periods between about
W UMa stars are very common, comprising some 95% of eclipsing binary variables in the solar neighbourhood, or one star in every 1000 - 2000 in the same spectral range (Eggen, 1967).
The effective temperatures of the primary and secondary stars in W Uma-type variables are not exactly the same.

 W Ursae Majoris star
In W UMa systems, the components stars, which are of spectral type F or G and lie on or near the mean sequence, form a contact binary and have pulled each other into teardrop shapes.
The primary and secondary minima are virtually the same (some 0.6 to 0.8 magnitude deep) and there's a continuous light variation throughout the orbit, with no clear start or end to an eclipse.
W Ursae Majoris itself lies 162 light-years away and consists of two stars not unlike the Sun, the primary with a mass of 0.99 M

 W Ursae Majoris - Wikipedia, the free encyclopedia
W Ursae Majoris (W UMa) is a variable star in the constellation Ursa Major.
It is an eclipsing contact binary whose two component stars share a common outer layer, and is the prototype of a class of contact binary variables known as W Ursae Majoris variables.
Unlike with normal eclipsing binaries, the contact nature makes it impossible to tell when an eclipse of one component by the other starts or ends precisely.

Pouco afeita a uma luta mais selvagem pela vida, a galinha tinha que decidir por si mesma os caminhos a tomar, sem nenhum auxílio de sua raça.
Mas quando todos estavam quietos na casa e pareciam tê-la esquecido, enchia-se de uma pequena coragem, resquícios da grande fuga — e circulava pelo ladrilho, o corpo avançando atrás da cabeça, pausado como num campo, embora a pequena cabeça a traísse: mexendo-se rápida e vibrátil, com o velho susto de sua espécie já mecanizado.
Uma vez ou outra, sempre mais raramente, lembrava de novo a galinha que se recortara contra o ar à beira do telhado, prestes a anunciar.

 XX Leo: Eclipsing Binary Star
As is expected for an A-Type W UMa, in both the V and R bands, the secondary minimum has a flat bottom, whereas the primary minimum has a rounded bottom; the maxima are also rounded.
If this system truly is an A-type W UMa, as the shape of the light curve suggests, then it is an unusual system because it has an unusually long period for a star of this type, almost one day long (by definition W UMa stars have periods less than one day long).
He did, however, indicate that there were very few W UMa systems with periods around one day detected in his studies, which, in part, could be a factor of the Earth's rotation limiting observations, but could also be an actual phenomena of these stars.

Figure 5, my light curve, has a difference of 0.04 magnitudes between the first and second minima; the W UMa RZ Tauri EB¼s magnitude difference between minima is 0.05.

There are serious uncertainties concerning mainly the energy transfer in W UMa type systems and the region of the energy transfer in these systems is analysed.
It is found that the energy transfer is taken place in the radiative zones, rather than in the convective zones.
The observations and theory of W UMa systems had shown that the magnetic activity level in W UMa systems is lower than that in similar but non-contact stars or fast-rotating single stars, but the mechanism for this effects is not known.

 A Statistical Study of the O'Connell Effect of W UMa Binaries   (Site not responding. Last check: 2007-10-08)
Many W UMa binaries exhibit the O'Connell effect, usually explained by spots on the surface which are responsible for variations in the intensity of the system.
An attempt has been made to analyze these variations in each star by measuring the difference in integrated flux from the system for 0.0 to 0.5 phase vs. 0.5 to 1.0 phase.
The eventual goal is to look at all W UMa's with good photometry to compare the degree of O'Connell effect with such parameters as degree of contact and mass ratio of the system.
