- What is the significance of the color of a star? O The color tells how far away the star is O The color reveals the temperature (and often the size) of the star O The color is not scientifically important O The color tells the relative motion of the star to Earth (toward/away)What is the advantage of using a meter stick with millimeter divisions over a meter stick with centimeter divisions?A certain star has a (B-V) color index of 0.61 and a B magnitude of 6.87. How many times brighter is this star when measured using a V filter than when using a B filter?
- Star 1 and star 2 have the same V-magnitude, V = 7.5. However, they have different B-magnitudes, B1 = 7.2 and B2 = 8.5. What are the (B − V) colors of the two stars?6) Estimate the distance to the star with absolute magnitude -5.6 and apparent magnitude 0.75Given a star has a absolute magnitude of 2.5 and an apparent magnitude of 10.0.
