Betelgeuse is a nearby supergiant that will eventually explode into a supernova. Let's see how awesome it would look. At peak brightness, the supernova will have a luminosity of about 10 billion times the Sun. It is 600 light-years away. All stellar brightnesses are compared with Vega, which has an intrinsic luminosity of about 60 times the Sun, a distance of 25 light-years, an absolute magnitude of 0.6 and an apparent magnitude of 0 (by definition). a) At peak brightness, how many times brighter will Betelgeuse be than Vega? b) Approximately what apparent magnitude does this correspond to? c) The Sun is about -26.5 apparent magnitude. What fraction of the Sun's brightness will Betelgeuse be?
Describe how energy generated in the core of a 1-solar-mass star gets to the star's surface.
Match each statement with the appropriate item (If the first corresponds to B and the next 4 to C, enter BCCCC) 1) stars that have evolved off the main sequence and are growing in luminosity due to a hydrogen burning shell 2) young, spread out star cluster 3) cooler stars in a cluster that have not yet evolved off the main sequence 4) stars that are burning helium in their core 5) old, dense star cluster A. red-giant branch B. open cluster C. lower main sequence D. horizontal branch stars E. globular cluster
A red giant star has a temperature of 3900 K and a luminosity of 13600 LSun. How many times bigger is this star than the Sun? Hint: You need the surface temperature of the sun for this problem. Use the value in the book, 5800K.
List the following 5 terms in order through a stars life cycle (starting with the sun), through the remainder of its lifetime: a. Black dwarf b. Planetary nebula c. Red giant d. Star (Sun) e. White dwarf
Which statement is most logical? a First stars are thought to have been more massive than Sun because the materials used to make clouds were more abundant at the beginning b First stars are thought to have been more massive than Sun because the temperatures of the clouds that made them were higher because they consisted entirely of hydrogen and helium c First stars are thought to have been more massive than Sun because star-forming clouds were much denser early in time d First stars are thought to have been more massive than Sun because the clouds that made them were much more massive
what is the mass of a star with a main- sequence lifetime of 3 billion years
Match each characteristic below of a one-solar-mass star to its appropriate phase. Answer M for Main-sequence Star, or P for Protostar. If the first is M and the rest P, enterMPPPPPP). A) energy generated by nuclear fusion B) pressure and gravity are NOT precisely balanced. C) surface radiates energy at same rate that core generates energy D) radius much larger than the Sun E) energy generated by gravitational contraction F) lasts about 10 billion years G) luminosity much greater than the Sun
