Deriving the orbital properties of pulsators in binary systems through their light arrival time delays
Deriving the orbital properties of pulsators in binary systems through their light arrival time delays
We present the latest developments to the phase modulation method for finding binaries among pulsating stars. We demonstrate how the orbital elements of a pulsating binary star can be obtained analytically, that is, without converting time delays to radial velocities by numerical differentiation. Using the time delays directly offers greater …
