Abstract


This paper deals with the light travel time effect in binary systems with variable components. The methods for estimation of the orbital elements relying on the parameters obtained through Fourier decomposition of the respective timing / O − C data, are reviewed. Some new formulae are derived and some qualitative remarks on the adopted methodology are discussed. Finally, some issues related to the presence of time gaps in the analysed data and to the case of noisy data are addressed.
