What is the shape of the surface of equal gravitational potential of a single star? double star?
| September 23, 2020 | Education
The equipotential surface (φ = GM / r = const) around a single star has a spherical shape. In a close binary system, the surface of equal gravitational potential is close to the shape of an ellipsoid. At a great distance from the binary star, the equipotential surface again acquires a spherical shape.
