C) in terms of t,” how is the habitable zone around the star defined? 4 marks d) on the main sequence the luminosity, l, of a star of mass m can be approximated as l=m". where both l and m are expressed in solar units. hence show that the orbital velocity of a planet at the inner edge of the habitable zone around a star of mass m scales as 1/m1/2 7 marks]
