    A 6.5-day periodicity in the recurrent nova V404 Cygni implying the presence of a black hole

    Two years after its outburst in 1989, the William Herschel Telescope has been used to find absorption features in V404 Cyg characteristic of a late G or early K...

    Period, epoch, and prediction errors of ephemerides from continuous sets of timing measurements

    Space missions such as Kepler and CoRoT have led to large numbers of eclipse or transit measurements in nearly continuous time series. This paper shows how to...

    Precision Ephemerides for Gravitational Wave Searches. II. Cyg X-2

    Accreting neutron stars in low-mass X-ray binaries are candidate high-frequency persistent gravitational wave sources. These may be detectable with next...

    Precision Ephemerides for Gravitational-wave Searches - III. Revised system parameters of Sco X-1

    Neutron stars (NSs) in low-mass X-ray binaries are considered promising candidate sources of continuous gravitational waves. These NSs are typically rotating...

    Precision Ephemerides for Gravitational-wave Searches - IV. Corrected and refined ephemeris for Scorpius X-1

    Low-mass X-ray binaries have long been theorized as potential sources of continuous gravitational-wave radiation, yet there is no observational evidence from...
