True or False
8. Almost all stars are in binary systems. The book says: "So far you have been considering the deaths of stars as if they were all single objects that never interact, but more than half of all stars are members of binary star systems."From this, I would not necessarily say that almost all stars are in binary systems based on this alone, but some other information I am finding says up to 85%. However, the numbers seem to be all over the map outside the course material, and I can not find a solid figure in it from what I have looked at.
If it helps, Stars and Galaxies, 10th Edition by Seeds and Beckman is my reference material.
Choose the correct statements from the following list referring to white dwarfs. (Give ALL correct answers, i.e., B, AC, BCD...)
A) The pressure that balances gravity in a white dwarf is called degenerate electron pressure.
B) The power source of white dwarfs is left-over heat.
C) White dwarfs cool slowly because they are small and eventually fade-out to become black dwarfs.
D) White dwarfs with mass greater than 1.4 times the Sun's mass cannot exist.
E) Stars with a mass like the Sun will end up as a white dwarf star.
F) White dwarfs are less dense than red giants.
G) White dwarfs are the coolest main sequence stars.
What kind of star is most likely to become a white-dwarf supernova?
A. a star like our Sun
B. a white dwarf star with a red giant binary companion
C. a pulsar
D. an O star
Is the answer B?
For D, as the surface temperature of a star would change over time so spectral type cannot tell us about the fate of the stars?

- Based on what you learned about the source of stellar energy and how stars make energy, select all of the correct statements from the following list. 1. Many stars make energy with the proton-proton cycle. 2. The CNO cycle is more efficient than the proton-proton cycle. 3. The sun's energy comes from the CNO cycle.More massive stars make energy with the proton-proton cycle. 4. The leftover mass in both the proton-proton cycle and the CNO cycle is converted to energy. 5. A helium atom is more massive than four hydrogen atoms. 6. The CNO cycle requires a higher temperature than the proton-proton cycle.arrow_forwardWhich of the following most correctly explains why we have not yet observed any white dwarfs derived from M stars: Group of answer choices Most M stars end up as neutron stars or black holes. The lifetime of M stars is longer than the age of the universe. Most M stars are located near the edge of the universe, beyond the visible horizon. Most M stars are members of a binary system, and the white dwarf would be obscured by the glare of the more massive companion. White dwarfs are too dim to be observed with currently available techniques.arrow_forwardBased 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.arrow_forward
- Give ALL correct answers referring to the properties of known stars, i.e., B, AC, BCD... A) On the main sequence, more massive stars are colder. B) High mass stars are the most numerous type of stars observed in the galaxy. C) Giants are colder than main sequence stars at the same luminosity. D) Giants are brighter than dwarfs at the same temperature. E) On the main sequence, more massive stars are dimmer. F) White dwarf stars are much denser than main sequence stars. Hint: White dwarf stars have about the mass of our sun, but are only the size of the Earth. Therefore, they have a very high density.arrow_forwardAll massive main sequence stars reside in clouds of glowing gas. The four powerful stars in the center of the Orion Nebula are good examples. Lower mass stars like the Sun generally don't have clouds of gas around them. a. Why do powerful stars reside in gas clouds? b. What is making the gas glow exactly? For the last question, refer to the surface temperature of these stars, and to Wien's Law.arrow_forwardYou discover a binary star system in which one member is a 15 solar-mass main-sequence star and the other star is a 10 solar-mass giant. Why should you be surprised, at least at first? A. It doesn't make sense to find a giant in a binary star system. B. The two stars in a binary system should both be at the same point in stellar evolution; that is, they should either both be main-sequence stars or both be giants. C. The two stars should be the same age, so the more massive one should have become a giant first. D. The odds of ever finding two such massive stars in the same binary system are so small as to make it inconceivable that such a system could be discovered. E. A star with a mass of 15 solar-mass is too big to be a main-sequence star.arrow_forward

Group of answer choices The event confirmed theoretical predictions that much of the energy of a supernova explosion is emitted in the form of neutrinos. Supernova 1987A was the first observable supernova in the Milky Way since the invention of the telescope. Because supernova 1987A was relatively close and very little dust intervenes between us and the Large Magellanic Cloud, from which the supernova originated, astronomers were able to figure out its total energy output with pretty good accuracy. The neutrinos preceded the light because they escaped during the collapse, whereas the first light of the explosion was emitted only after the supernova shock had plowed through the body of the star to the surface. Supernova 1987A represented the first time astronomers had observed a star and knew its basic properties before it exploded.arrow_forwardWhich of the following types of data provide evidence that helps us understand the various stages of the life tracks of low-mass stars? A. H-R diagrams of open clusters B. spacecraft observations of the Sun C. observing a low-mass star over many years D. H-R diagrams of globular clustersarrow_forward

E) Supported by electron degeneracy pressure. F) Typically about the size of Earth. G) Usually has a very strong magnetic field. H) Viewed from afar, time stops at its event horizon. Answer: Submit All Answersarrow_forwardWhich of the following is least reasonable regarding novae and supernovae? Group of answer choices A type I (carbon-detonation) supernova results when a white dwarf in a binary system absorbs enough mass from its companion to push it over the Chandrasekhar limit. A type II supernova results from any supermassive star at the end of its life, when it runs out of fusion energy and collapses. A nova can occur multiple times in a binary system. If a white dwarf in a binary system absorbs enough mass to go beyond the Chandrasekhar limit, the white dwarf explodes as a supernova. The reason a type I supernova does not produce hydrogen lines is that the explosion originates from a stellar core (white dwarf), where hydrogen has already fused to produce heavier elements (so there is no longer any hydrogen). More supernovae are observed in the Milky Way because they are much closer to us than those in other galaxies.arrow_forward
