An analysis of all available times of minimum light suggests that the orbital period is increasing continuously at a rate of P-dot =+3.48 (±0.23)×10 {sup −7} days yr {sup −1}.

WebSep 1, 1982 · The system is found to be semi-detached where the less massive component fills its Roche surface, whereas the other component almost does so. The configuration of the system is shown in Fig. 1. The absolute dimensions of the system are found to be M1 = 0.61M⊙, M 2 = 0.41 M ⊙ R 1 = 1.15 R, and R 2 = 0.96 R ⊙. Binary stars are classified into four types according to the way in which they are observed: visually, by observation; spectroscopically, by periodic changes in spectral lines; photometrically, by changes in brightness caused by an eclipse; or astrometrically, by measuring a deviation in a star's position caused by an unseen companion. Any binary star can belong to several of these classes; for …
