Consider an unresolved binary star at d= 500pc consisting of an A1V dwarf and a K0III giant star.

A) Compute the apparent magnitudes, m_b and m_v, and the color (B-V) of this object.

B) Now imagine it to be an eclipsing binary star. What are the apparent magnitudes, m_b and m_v, and color (B-V) of the system when the K star is eclipsed by the A star (the A star passes in front of the K star)

C) What are the apparent magnitudes, m_b and m_v, and color (B-V) of the system when the A star is eclipsed by the K star
