Binary Stars • Apparent Binaries – Chance projecon of two disnct stars along the line of sight. – Oen at very different distances. • True Binary Stars: – A pair of stars bound by gravity. – Orbit each other .

  An eclipsing binary star is a binary star in which the orbit plane of the two stars lies so nearly in the line of sight of the observer that the components undergo mutual eclipses. In the case . ellipticity and O’Connell). Eclipsing binary stars are believed to show distinct eclipses only if belonging to the EA (Algol) type.
