A catalogue of potentially bright close binary gravitational wave sources [PDF]

open access: yes
This is a current print-out of results of a survey, undertaken in the spring of 1985, to identify those known binary stars which might produce significant gravitational wave amplitudes at earth, either dimensionless strain amplitudes exceeding a ...

Period and light-curve study of the contact eclipsing binary V523 Cas

New Astronomy, 2016
Abstract CCD photometry of the eclipsing W Uma binary system V523 Cas in U, B, V and RC filters was carried out during eight nights in 2012. The physical and geometrical parameters of this system are obtained. A possible pulsation period of one of the components is obtained by analyzing the residuals of the ephemeris light curve.

Orbital Period Changes of Two Very Short-Period W UMa Stars CC Com and V523 Cas: A Possible Evidence for TRO Plus AML Model

Astrophysics and Space Science, 2001
Orbital period changes of the two very short-period contact binaries, CC Com and V523 Cas, are presented. It is shown that the period of CC Com varies in secular decrease with rate of dP/dt = -4.39 x 10(-8) days/year, while the period of V523 Cas is increasing at rate of dP/dt = +9.09 x 10(-8) days/year.
