| Abstract: | We examine the influence of mass-loss due to stellar wind using the celestial mechanics of variable mass, and derive first-and
second-order solutions, taking into account the decreasing mass due to the stellar wind. The theoretical results show that
the semi-major axis exhibits secular and periodic variations in the first-and second-order theory. The orbital eccentricity
exhibits periodic, but no secular variation or changes. The longitude of periastron exhibits only periodic variations in the
first-order solution, but also secular variations in the second-order solution. The theoretical results are applied to the
binary star HD 698, and variability of the orbital elements of this star due to stellar-wind mass loss calculated.
