How high or low a star is on the main sequence is dictated primarily by ... Select one: A. its chemical composition B. the fraction of metals in its atmosphere C. what elements are fusing in its core D. the size of its photosphere E. its mass
Select all of the statements about the main sequence stage in the life of a star that are TRUE: All stars spend the majority of their lives in the main sequence stage. Most stars lose a significant amount of mass while they are on the Main Sequence. Different stars spend a different amounts of time (number of years) in the main sequence stage, depending on the characteristics they were born with. Main sequence stars are rare in the Galaxy, so we are lucky to be living around one. During the main sequence stage, energy to power the star is provided by the fusion of hydrogen.
7. Let's characterize a typical neutron star. (a) Compute its luminosity in units of the solar luminosity.

(c) In which region of the spectrum it will be easier to detect / observe such an object (look at Figure 2)? mmmmmm 0.0001 nm 0.01 nm Gamma rays 400 nm Increasing energy X-rays Increasing wavelength 10 nm 1000 nm 0.01 cm Ultra- violet Infrared Visible light 500 nm 600 nm Figure 2: Electromagnetic spectrum 1 cm 1m Radio waves Radar TV FM 700 nm 100 m AM
Based on what you learned about stellar evolution, select all of the correct statements from the following list. 1. The period of some Cepheid variables actually changes. 2. When getting dimmer, variable stars are releasing energy; when getting brighter they are storing energy. 3. variable stars are expanding and contracting 4. despite their variability, variable stars stay in a specific position on the H-R diagram. 5. A changing period in a Cepheid variable means that the size of the star is changing and that the star is therefore evolving. 6. Only stars on the instability strip are variable. 7. More massive stars will vary their brightness more quickly.

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. E Without first knowing the distances to these stars, you cannot draw any conclusions about how their true luminosities compare to each other.
Which of the following statements is/are true regarding a nebula? Which of the following statements is/are true regarding a nebula? It is believed that each planet in our solar system began as its own nebula. Over time, a nebula becomes cooler and grows in size. The density of a nebula is greatest at the edges and least in the center. There are no nebulas left in our galaxy because they have all formed stars and planets. Over time, a star will form at the center of a nebula.

B) White dwarfs are composed mostly of hydrogen. C) A white dwarf is the remnant of the star's core visible after the outer layers have been ejected. D) A planetary nebula is the remnant of the outer envelope of a star. E) White dwarfs are small dense objects about the size of the Earth.
For the PP chain 0.7% of the mass participating in nuclear fusion is liberated as energy which produces a star's luminosity. Assume that the core of a main sequence star consists of 10% of its total mass. Hence, estimate the lifetime of a star on the main sequence in terms of its luminosity L/L. Give your answer in years. You may use the observed mass-luminosity relation L x M³.5, where M is the star's total mass. Using typical values, calculate estimates for the main sequence lifetime of a KO star and a 05 star. Describe briefly why your estimate might be more accurate for K stars compared to O stars.
