12. A star with spectral type MO has a surface temperature of 3750 K and a radius of 0.63 Rsun: How many times more luminous is this star than the Sun? (if it is less luminous enter a number less than one) Answer: Submit All Answers Last Answer: 0.0923 Incorrect, tries 1/5. Hint: Use the Luminosity equation, which says that L is proportional to R^2 T^4. If you keep these as ratios compared to the sun, your L will also come out as a ratio compared to the Sun. This star has a mass of 0.4 Msun- Using the simple approximation that we made in class, what is the main sequence lifetime of this star? You may assume that the lifetime of the sun is 1010 yr. Answer: Submit All Answers Compare this to the lifetime of a MO star listed in Table 22.1 (computed using a more sophisticated approach). Is the value you calculated in the previous problem longer or shorter than what is reported in the table? (L for longer, S for shorter) (You only get one try at this problem.)

Problem 4. Stellar Temperature, Color, and Size a) (Palen, et. al., 2nd, Problem 45) Rigel has a Hipparcos parallax of 0.00412 arcsec. Given Rigel and Betelgeuse appear almost equally bright in the sky, i) which star is actually more luminous? ii) Betelgeuse appears reddish while Rigel appears bluish white. Which star is larger and why? b) (Palen, et. al., 2nd, Problem 46) Sirius is actually a binary pair of two A-type stars. The brighter and fainter of the pair is called the Dog Star and Pup Star, respectively (they are in the constellation Canis Major). The Dog Star is 6,000 times brighter than the Pup Star even though both stars are the same distance from us. Compare the i) temperature ii) luminosities iii) sizes (radii) of these two stars.

14 Suppose you see two main-sequence stars of the same spectral type. Star 1 is dimmer in apparent brightness than Star 2 by a factor of 100. What can you conclude? (Neglect any effects that might be caused by interstellar dust and gas.) A B C D Star 1 is 10 times more distant than Star 2. The luminosity of Star 1 is a factor of 100 less than the luminosity of Star 2. Star 1 is 100 times nearer than Star 2. Star 1 is 100 times more distant than Star 2.
