Is a star's outer layer hot and dense?
Yes, a star's outer layer, called the photosphere, is hot and dense. This is where most of the visible light and heat emitted by the star originate. The temperature and density of the photosphere vary depending on the type and age of the star.
What is the process that causes an aging star to swell up into a red giant?
As a star runs out of hydrogen fuel in its core, the core contracts and heats up, causing the outer layers of the star to expand and cool, turning the star into a red giant. This expansion is due to the increased radiation pressure from the core and the star's gravitational pull on its outer layers.
What forms when a main sequence star that had been contracting suddenly expands and cools?
When a main sequence star that has been contracting suddenly expands and cools, it can transform into a red giant. This phase occurs as the star exhausts its hydrogen fuel in the core, leading to gravitational collapse and subsequent heating, which causes the outer layers to expand and cool. During this process, the star's outer envelope becomes much larger and redder, while the core may start fusing helium or heavier elements, depending on the star's mass. Eventually, the star may shed its outer layers, leading to the formation of a planetary nebula or, in more massive stars, a supernova.
What is produced when the outer core of the star explodes after the core collapses?
Supernova
What is produced when the outer core of star explodes after the core collapses?
Supernova
Is the Photosphere the outer layer on a star?
Magnetosphere is the layer above the photospere.
Is a star's outer layer hot and dense?
Yes, a star's outer layer, called the photosphere, is hot and dense. This is where most of the visible light and heat emitted by the star originate. The temperature and density of the photosphere vary depending on the type and age of the star.
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
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.
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
What is the process that causes an aging star to swell up into a red giant?
As a star runs out of hydrogen fuel in its core, the core contracts and heats up, causing the outer layers of the star to expand and cool, turning the star into a red giant. This expansion is due to the increased radiation pressure from the core and the star's gravitational pull on its outer layers.
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 outermost layer of a star?
The outermost layer of a star is the photosphere. It is the visible surface of the star where most of the light is emitted.
How does a star get into outer space?
through a spaceship get it star celebrity into outer space thorough a spaceship oh whatever
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.
When does a red star become a red giant?
A star become a red giant when the core contracts, the temperature increases and the outer layers of the star begin to expand. By the end of this phase, the star can be 10 to 100 times it diameter. When the temperature in the core reaches 100 000 000°C, the helium start fusing into carbon. Because the star has expanded to such an enormous size, that the outer layer are much cooler than when the star was a main sequence star. It therefore appears red, earning the name of red giant.
