Two white dwarfs A and B have the same effective temperature T 10600 K. A Brown dwarfs eventually collapse to become white dwarfs.
White Dwarfs Facts About The Dense Stellar Remnants Space
It is the result of the core collapse of a low-mass star that sheds its outer layers.
. A The life of a white dwarf is an ongoing battle between electron degeneracy pressure and neutron degeneracy pressure. C All brown dwarfs have masses less than about 8 that of our Sun. High-mass stars can leave behind white dwarfs.
Felt inside a white dwarf is a consequence of the fact that all electrons are. B Brown dwarfs form like ordinary stars but are too small to sustain nuclear fusion in their cores. Degeneracy pressure keeps any protostar less than 008 solar mass from becoming a true.
This example becomes even more interesting when you consider the original versions from the Grimm Brothers and from Hans. Which of the following statements about degeneracy pressure is not true. B Brown dwarfs are supported against gravity by degeneracy pressure which does not depend on the objects temperature.
B Both electron degeneracy pressure and neutron degeneracy pressure help govern the internal structure of a main-sequence star. Which of the following statements about brown dwarfs is not true. Asked Nov 21 2019 in Physics Space Science by mattflintop.
C A white dwarf is the remnant of the stars core visible after the outer layers have been ejected. The normal course of evolution for a Sun-like star is to become a white. D If we observe a Type II supernova and do not see a pulsar afterward at the same location we know a black hole must be present there.
Which of the following statements about white dwarfs is correct. Which statements are true of a white dwarf. It cools down to become a black dwarf.
It has a red shell. If the first is T and the rest are F enter TFFFF A A planetary nebula forms when a star violently explodes. C Brown dwarfs form like ordinary stars but are too small to sustain nuclear fusion in their cores.
A Brown dwarfs are supported against gravity by degeneracy pressure which does not depend on the objects temperature. B White dwarfs are composed mostly of hydrogen. Identify elements of each story that encourage an independent self or an interdependent self.
High-mass stars can explode in. Which one of the following statements about white dwarfs is TRUE. D Brown dwarfs form like ordinary stars but are too small to sustain nuclear fusion in their cores.
A Brown dwarfs are supported against gravity by degeneracy pressure which does not depend on the objects temperature. Indicate whether the following statements are true or false Select T-True F-False. Degeneracy pressure varies with the temperature of the star.
High mass stars can collapse into black holes. C Once a pulsar forms it typically lasts for billions of years. Degeneracy pressure supports white dwarfs against gravity.
It strongly attracts all matter or energy that comes near it. It emits massive amounts of light compared with other stars. White dwarf B has a mass of 0125 Msun 18 Msun.
Up to 256 cash back Which of the following statements about degeneracy pressure is not true. Asked Sep 24 2016 in Physics Space Science by GeniusbyDesign. Their core is composed mainly of carbon and oxygen.
White dwarf A has a mass of 10 Msun and a radius of 0025 Rsun. A neutron star or a black hole. The statements which are true with the white dwarf are it is the result of the core collapse of a low mass star that sheds its outer layers and it cools down to become white dwarf.
Which of the following objects is produced by a collapsing star core that exceeds the Chandrasekhar limit. The white dwarf is one which is formed from the sun and sheds its outer layers in order to form a white nebula. E Pulsars cannot be rotating white dwarfs because their rotation rate is so high that a white dwarf would be ripped apart.
Degeneracy pressure can halt gravitational contraction of a star even when no fusion is occurring. High mass stars can produce planetary nebulae. Which of the following statements are true regarding the death of high-mass stars.
Think of the popular but gruesome fairy tales of Snow White and the Seven Dwarfs and The Little Mermaid. B Brown dwarfs eventually collapse to become white dwarfs. C Brown dwarfs eventually collapse to become white dwarfs.
Electron degeneracy pressure is necessary to sustain a white dwarf against gravitational collapse. Degeneracy pressure keeps any protostar less than 008 solar mass from becoming a true hydrogen-fusing star.
