On the Main Sequence Stars Obtain Their Energy

C by converting hydrogen to helium. D by converting helium to carbon nitrogen and oxygen.

Main Sequence Universe Today

The total pressure is where and are center star gas and radiation pressure respectively.

. A main sequence star chart or Hertzsprung-Russell HR diagram shows the relationship. Stars more massive than the Sun obtain their energy while on the main sequence from. D by converting helium to carbon nitrogen and oxygen.

We can write and. The main sequence has a limit at the lower end because. C by converting hydrogen to helium.

Main sequence stars are characterized by the fusion hydrogen into helium in their cores to produce energy. Through theoretical modeling of the Sun and other main sequence stars scientists have determined that the factor that differentiates them from the three other types of stars is the fact that their energy is generated internally by the conversion of hydrogen to helium giants and supergiants produce their energy by gravitational contraction and by converting helium to even. On the main sequence stars obtain their energy A from chemical reactions.

For the bulk of its lifetime a star fuses hydrogen into helium in its core. Stellar energy generation on the main sequence. On the main sequence stars obtain their energy A from chemical reactions.

All of the above. B from gravitational contraction. It is the dominant process in our Sun and all stars of less than 15 solar masses.

A from chemical reactions. During this time the star sits somewhere on the main sequence in the HR diagram. Most main-sequence stars have a mass in the range about to solar mass.

Low mass stars form from the interstellar medium very rarely. C apparent brightness of the star in our sky. By converting hydrogen to helium.

B distance to the star. E from nuclear fission. D by converting helium to carbon nitrogen and oxygen.

All main sequence stars including the sun produce energy by nuclear fusion whereby hydrogen atoms are combined to form helium. Group of answer choices by converting helium to carbon nitrogen and oxygen. C The diagram shows main-sequence stars of every spectral type except O along with a few giants and supergiants.

On the main sequence stars obtain their energy by converting hydrogen to helium which of the following luminosity classes refers to stars on the main sequence. B-type main sequence star. D by converting helium to carbon nitrogen and oxygen.

E from nuclear fission. B from gravitational contraction. B from gravitational contraction.

E from nuclear fission. The net effect of the process is that four hydrogen nuclei protons undergo a sequence of fusion reactions to produce a helium-4 nucleus. The luminosity of the Sun is the total amount of energy that is emitted by the Sun every second.

C from nuclear fission. Ngc 584 Research Paper. B from gravitational contraction.

E from chemical reactions. On the main sequence stars obtain their energy A from chemical reactions. Once fusion reactions begin at the center of a cloud of gas we call the object a star.

C by converting hydrogen to helium. The main process responsible for the energy produced in most main sequence stars is the proton-proton pp chain. 27 On the main sequence stars obtain their energy A by converting hydrogen to helium.

B from gravitational contraction. If you slew 1 degree to the north you will encounter a pair of bright stars one shining at 59 magnitude and the other at 74 magnitude in brightness. B The diagram shows main-sequence stars of all the spectral types except O and B along with a few giants and supergiants.

C by converting hydrogen to helium. 30 On the main sequence stars obtain their energy. Any star that is more massive than 8 solar masses will undergo a supernova explosion and leave behind a black-hole remnant.

On the main sequence stars obtain their energy. All of the above. C by converting hydrogen to helium.

A catastrophic loss of mass occurs in. D The diagram shows no main-sequence stars at all but it has numerous supergiants and white dwarfs. If enough mass is accreted by a neutron star it will undergo a supernova explosion and leave behind a black-hole remnant.

A spectral type of the star. B from gravitational contraction. E from nuclear fission.

Energy can flow outward from the cores of different kinds of stars by. The thing the main sequence stars have in common is that they get their energy from the fusion of hydrogen hydrogen-1 is converted into helium-4. D rotation rate of the star.

On the main sequence stars obtain their energy A from chemical reactions. A black hole forms when two massive main-sequence stars collide. 28 Which of the following best describes convection.

They are composed by a mixture of nonrelativistic gas and radiation that are stood in hydrostatic equilibrium by gravity. The CNO cycle c. D by converting helium to carbon nitrogen and oxygen.

Hot and luminous if it is massive or cool and dim if it is a lightweight. See full answer below.
