THE TRUE AND APPARENT ELLIPTICAL ORBITS OF A VISUAL BINARY STAR

Yıl 2018, Cilt: 60 Sayı: 2, 51 - 62, 01.08.2018

Öz

Observation of binary star orbits reveals only the apparent orbit of these two celestial
bodies which differs from the true orbit. Due to the inclination of the plane of the true orbit one
can only observe its projection onto the plane of sky. Computing the true orbit from the apparent
orbit is based on constructing the auxiliary ellipse. This process is well known (Kallrath 2009) but
requires arduous numerical computations. In this paper a simpler approach to obtain the auxiliary
ellipse is presented and its derivation is provided. This approach finds out that the coefficients of
the auxiliary ellipse are very simple functions of those of the apparent ellipse.
