Students have asked these similar questions
where do hydrogen-buring stars spend most of their time on the H-R Diagram? Is it the main sequence, the red gaint region, horizontal branch or the white dwarf region?
Star 1 emits energy at a rate that is 2 times that of Star 2. If Star 1 also has a radius that is 3 times larger than Star 2, how do the temperatures of the stars compare?
If a contracting protostar is two times the radius of the Sun and has a temperature of only 1890 K, how luminous will it be relative to the Sun?

- How would a white dwarf that formed from a star that had an initial mass of 1 MSunbe different from a white dwarf that formed from a star that had an initial mass of 9 MSun?arrow_forwardAccording to the text, a star must be hotter than about 25,000 K to produce an H II region. Both the hottest white dwarfs and main-sequence O stars have temperatures hotter than 25,000 K. Which type of star can ionize more hydrogen? Why?arrow_forwardWhich is easier to observe at large distances-a spectroscopic binary or a visual binary?arrow_forward
- Estimating the luminosity class of an M star is much more important than measuring it for an O star if you are determining the distance to that star. Why is that the case?arrow_forwardWhat observations or types of telescopes would you use to distinguish a binary system that includes a main-sequence star and a white dwarf star from one containing a main-sequence star and a neutron star?arrow_forwardIf the Sun were replaced by a white dwarf with a surface temperature of 10,000 K and a radius equal to Earth’s, how would its luminosity compare to that of the Sun?arrow_forward
- Apart from the masses, how are binary systems with a neutron star different from binary systems with a white dwarf?arrow_forwardIf a 3 and 8 MSunstar formed together in a binary system, which star would: A. Evolve off the main sequence first? B. Form a carbon- and oxygen-rich white dwarf? C. Be the location for a nova explosion?arrow_forwardAppendix J lists the stars that appear brightest in our sky. Are most of these hotter or cooler than the Sun? Can you suggest a reason for the difference between this answer and the answer to the previous question? (Hint: Look at the luminosities.) Is there any tendency for a correlation between temperature and luminosity? Are there exceptions to the correlation?arrow_forward
- Assume that you observe both of these stars in a galaxy 10 million light-years away. How bright is each of these supernovae? Star 1: Luminsoity= 1,100Lsun Star 2: Luminsotiy= 15,000Lsunarrow_forwardIf the Sun is well approximated by a black body with a temperature of 6,000◦ K, then how does its surface brightness compare (ratio) with the surface brightness of a 12,000◦ K star? How about a 3,000◦ K star?arrow_forwardWhat are the a) luminosity and b)wavelength of maximum emission for a star with a surface temperature is 2,000K and a size of 1.0*108m?arrow_forward
