Is a star's outer layer hot and dense?
Yes it is! Just like the sun. Its Corona is very hot.
How does Gravity play a role in the Death of a Star?
When a star runs out of energy, its mass is so great that the remaining energy cannot force the outer edges of a star away from its core, so the gravity causes the star to implode on itself.
What name is given to a layer of gases that covers a planet star or moon?
The layer of gases that covers a planet, star or moon is called the atmosphere.
Why do novae repeat while supernovae do not?
The explosion of novae hardly disturb the white dwarf or its companion star. Mass transfer resumes and a new layer of fuel can accumulate so that the process can happen all over again. In a supernovae, its the death of a star. Its theory that the outer layers of a massive star produces the supernovae while the core collapses to form a neutron star or black hole.
How does sun-like star evolve and die?
An average star, which is what our sun is, will actively fuse hydrogen into helium for a few billion years (exact time varies based on mass), then it slowly expands int a giant star. Then, the star's outer layer of gases puff off and become a planetary nebula, where its hot core is exposed as a white dwarf. The star reddens and cools, then stops burning and becomes a black dwarf.
Is the Photosphere the outer layer on a star?
Magnetosphere is the layer above the photospere.
Where on a star is the photosphere?
The photosphere is the outer part of the star that is visible, inside which the star becomes opaque to visible light. The photosphere is the layer below the star's atmosphere (the chromosphere, and so forth).
What is formed when an average size star uses up it's fuel and it outer layer expands?
A Red Giant
Is a star's outer layer hot and dense?
Yes it is! Just like the sun. Its Corona is very hot.
How do different scientists spectra to figure out the composition of a star's outer layer?
The color of the light radiated by the spectra can show the internal composition as well as the gases burning on the outer layer. Red stars are colder and blue stars are hotter.
What layer in the atmosphere do meteors come from?
Meteors come from outer space and crash into our atmosphere which burns them. That's what a shooting star is.
How do you create a shining star with Photoshop?
A simple version - Draw a star (on a transparent background and fill the start with white. Go to Layer - Layer style and set the layer style to outer glow , set the size to about 80% and the opacity to 40% The star shape may also be in the default shapes in the tool bar depending on you version of PS
How does Gravity play a role in the Death of a Star?
When a star runs out of energy, its mass is so great that the remaining energy cannot force the outer edges of a star away from its core, so the gravity causes the star to implode on itself.
What is produced when a red giant explodes?
Depends on the mass of the star. A star the size of our Sun will eject its outer layers, forming a planetary nebula with the core of the star exposed, cooling to become a white dwarf. Larger mass stars will explode as a supernova, creating a shock wave of stellar matter, the core either condensing to a neutron star or a black hole.
Suns core releases heat by what process?
Our sun release energy by a process called convection. Inside the star, energy is transported towards the surface through radiation, but about 1/3 of the outer layer of the star is markedly cooler than the core and the energy is transported by convection from the core to this layer.
When a star has exhausted its supply of hydrogen?
When hydrogen in the core of the star is depleted, a balance no longer exists between pressure and gravity. Core contracts, temperatures incrase. This causes outer layers to expand and cool. This star is called a GIANT.
What is the corona's job?
The corona of a star is the outer layer, mostly comprised of plasma. In the case of the Sun, the corona is what becomes visible in the event of a solar eclipse. Do not look directly at it. It can and will blind you.
