What type of star burns helium?
All red giant stars will start helium fusion when their core is compressed.
When a red giant loses its outer layer and the core shrinks to one millionth of its original size what type of star is formed?
When aÊstar completes it's Red Giant phase they become White Dwarfs. The Red Giant phase of stars takes about a billion years.
Is red giant a star or a type of star?
Red giant is a type of star.
What is life cycle of the sun?
The Sun is a G-type main sequence star. The Sun is 4.5 billion years old and will continue to fuse hydrogen into helium for approximately another 5 billion years. At this point the Sun will leave the main sequence as strong convection currents arise, becoming a red giant. During it's red giant phase, the Sun will fuse helium into heavier elements such as carbon.The outer layers of the Sun will escape as a planetary nebula, marking the end of the red giant phase. The core of the Sun will cool and contract, becoming a white dwarf.
What type of star is hadar?
Hadar is in its giant stage.
Red giant is a luminous giant star of low or intermediate mass that is in a late phase of its evolution with nuclear fusion going on in a shell outside the core but not in the core itself?
Thermonuclear fusion is still going on in the core of a red giant, but it is a different type of thermonuclear fusion. The center of the core has reached high enough temperature and pressure that it can now burn helium, producing carbon. 3 4He --> 12C The large amount of energy released by this type of fusion pushes the outer layers away, making a giant star. The expansion of volume of the surface layer causes it to cool, appearing red. Thus a red giant.
What type of fusion occurs in a high-mass star near the end stages of its life cycle?
helium capture
What type of reaction occurs when a thermonuclear bomb explodes?
A fusion reaction.
What type of eclipse occurs when the moon is in its full moon phase?
A Lunar eclipse occurs only when the moon is in its full moon phase.
What type of star burns helium?
All red giant stars will start helium fusion when their core is compressed.
What type of star would helium be converted to carbon as the final stage or fusion?
red giant (k12)
When a red giant loses its outer layer and the core shrinks to one millionth of its original size what type of star is formed?
When aÊstar completes it's Red Giant phase they become White Dwarfs. The Red Giant phase of stars takes about a billion years.
The helium flash occurs at what stage in stellar evolution?
As a G-type star fuses its hydrogen to helium, this helium will gather in the core. As a result, the core will contract under its own weight as hydrogen is being spent. The contraction causes an increased hydrogen fusion rate, increasing the temperature. When insufficient hydrogen remains in the core, the layers above are no longer supported by the outward pressure of radiation, and collapse on top of the core, causing it to contract further, and also initiating hydrogen fusion outside the core. At this point, the star leaves the main sequence, and becomes a red giant. At this stage, the core of the giant may reach critical density for helium fusion to initiate. Since the core is composed of mostly degenerate matter at this stage, there is no regulation of the fusion rate. Also, degenerate matter is less opaque to the energies produced than non-degenerate matter, so conducts them better.Ehr, to summarize: the helium flash occurs during the red giant stage of G-type stars.
What type of star is a Enif?
It is a star that has entered the super-giant phase. Its stellar classification is K2 1b.
What type of phase change occurs when a liquid changes into solid?
This physical change is called freezing.
Fusion is a type of?
Fusion is a type of
What type of nuclear reaction takes place in stars?
Nuclear fusion is the type of nuclear reaction that occurs in stars. Older stars with a collapsing center can exceed a temperature of one hundred million Kelvin.
