What else can I help you with?
What does a core of a star that has been stable for 1 million years have more of then are core that has been stable for 10 million years?
That would be Hydrogen. The star is converting Hydrogen to Helium over time, therefore the older the star is, the more Helium it contains.
What does the core of a star do when it blows its surface into space to form a planetary nebula?
When the core of a star blows its surface into space to form a planetary nebula, it sheds its outer layers of gas, exposing the hot, dense core of the star called a white dwarf. The white dwarf emits ultraviolet radiation that ionizes the ejected gas, causing it to glow and form the planetary nebula.
What chemical is more abundant the older a star is?
As a star ages, it fuses hydrogen into helium in its core. Therefore, helium becomes more abundant in older stars compared to younger stars.
What is a star called that begins as a large cloud of dust and gas?
A star that begins as a large cloud of dust and gas is called a protostar. It forms as gravity causes the dust and gas to clump together and initiate the process of nuclear fusion in its core.
What is the parts of the star?
It depends on how massive the star is and what part of its life its at. Most of the time the core is the hottest, but after a star runs out of its current fuel it will start fusing elements in a shell around its core out to the surface or photosphere. While these shells are burning they are the temporary hotspots of the star, while the core gets hotter and hotter.
Is the sun a gas giant or an rocky planet?
no its a star if it was a gas giant it would be a planet
How does a dying star shed its gases?
As a star runs out of fuel and starts to die, its outer layers expand and are pushed away by the strong radiation pressure from the core. This forms a glowing shell of gas called a planetary nebula. Eventually, the core collapses into a white dwarf, while the expelled gas dissipates into space.
What is a star called before it is born?
A star is called a protostar before it begins nuclear fusion in its core and officially becomes a star. During this stage, a protostar is formed from a collapsing cloud of gas and dust, as gravity pulls material together and heats up the core.
Compare the elements in an early prostar and those in a young star formed star dust of older stars?
In an early protostar, the dominant elements are hydrogen and helium with traces of heavier elements produced in previous stellar generations. In a young star formed from star dust of older stars, the composition will include heavier elements like carbon, oxygen, nitrogen, and iron, which were created in the cores of older stars and then dispersed into space through supernova explosions. These heavier elements enrich the gas and dust from which younger stars form, leading to a more diverse elemental composition.
Why does white dwarf star Sirius b have a mass comparable to the sun?
Gas doesn't weigh much, since a white dwarf is the core of a red giant. (the core is basically all the star's weight-the gases don't weigh much, so the weight doesn't differ much if a star lets go of all of its gas, since that's how white dwarfs are made)
What type of object is the Sun?
The Sun is a star, specifically a massive ball of glowing gas that emits light and heat through nuclear reactions in its core.
How does gas circulate the convective zone?
In the convective zone of a star, gas circulates through the process of convection. Hot gas rises to the surface, cools off, and then sinks back down into the interior. This continuous cycle of rising and sinking gas helps transport heat from the star's core to its outer layers.
