You are here: Variable classes

In this page you can see all the GCVS classifications. You can click the type and see a description of that below the table.

Information
We adopt a triple system of classifying eclipsing binary systems: according to the shape of the combined light curve, as well as to physical and evolutionary characteristics of their components. The classification based on light curves is simple, traditional, and suits the observers; the second and third classification methods take into account positions of the binary-system components in the (MV ,B-V) diagram and the degree of inner Roche lobe filling. Estimates are made by applying the simple criteria proposed by Svechnikov and Istomin (1979). The symbols for the types of eclipsing binary systems that we use are given below.

  • a) Classification based on the shape of the light curve
  • b) Classification according to the components physical characteristics
  • c) Classification based on the degree of filling of inner Roche lobes
