37. Jupiter at its present location, were a star? What would Earth be like ? Assume this hypothetical Jupiter with 75 × MJ would be a red dwarf with the same density as the Sun but a surface temperature of only 2500 K. What would be its total luminosity, compared to that of the Sun?

(Hint: recall that to be a star, Jupiter would have to be 75 times more mass than it has today.)

Soin: 02kg = 1.424x1029 kg ST Density of Sun, f= 1.4igm (cm3 = 1410 kg 1 m3 mous og Jupites, mie - 75*my = 75*1-8991021K9 = 1

    C. i. As a star runs out of hydrogen to fuel nuclear fusion in its core, changes within the star usually cause it to leave the main sequence, expanding and cooling as it does so. Would a star with a radius 100 times that of the Sun, but a surface temperature 0.4 times that of the Sun, be more, or less luminous than the Sun? Show and explain your reasoning.
