Black dwarf b. Planetary nebula c. Red giant d. Star (Sun) e. White dwarf
- What happens to a white dwarf when a normal star dumps mass to a white dwarf? Group of answer choices The white dwarf get smaller, causing its temperature and density to decrease. The white dwarf get smaller, causing its temperature and density to increase. The white dwarf get larger, causing its temperature and density to decrease. The white dwarf get larger, causing its temperature and density to increase.The Local Bubble is: a. a region of low density intersteller gas extending several hundred LY around the Sun b. a region around any exploding star where material is expanding from the explosion c. the region around very hot stars where hydrogen is ionizedDo this in 10 min. I will give like on answer
- Which 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.A star is listed in a catalog as being a type G2V.a) What is the star’s spectral class?b) What is the star’s luminosity class?c) What is the peak color of the star?d) Name an example of a star that has this type.Which of the following is the most reasonable statement regarding a neutron star? Group of answer choices It consists mostly or entirely of neutrinos. The most common component of a neutron star is hydrogen. The star will turn into white dwarf. All its electrons have been combined with protons. It consists of neutrons and protons floating in a sea of electrons.
