1) A planet has recently been detected around the star HD20945. This star is a K-type star and is fainter than the Sun. Its luminosity and mass are L = 0.25L and M = 0.85Mo, where Lo and Me represents the luminosity and mass of the Sun. First, let's determine the boundary of the Habitable Zone around HD20945. The inner and outer edges of the Habitable Zone around a star with luminosity L (in units of Lo) are approximately given by: Dinner = 0.95 VT Douter = 1.4 VT Here Dinner and Douter have units of AU. Recall that 1 AU is the Earth-Sun distance. Using these equations, determine the inner and outer edges of the Habitable Zone around HD20945 in units of AU.
