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 happens when a star loses its outer layer?
When a star loses its outer layer, it typically undergoes a process known as stellar mass loss. This can occur during various phases of a star's life, especially in the red giant phase or in the case of supernovae. The ejected material forms a nebula, while the remaining core may become a white dwarf, neutron star, or black hole, depending on the original mass of the star. This loss of outer layers also contributes to the enrichment of the interstellar medium with heavier elements forged in the star's core.
Is a star's inner layer cool and dense?
Yes, a star's inner layer, often referred to as the core, is typically extremely hot and dense. In the core, nuclear fusion occurs, generating the energy that powers the star. While the outer layers of a star may be cooler, the core's conditions are crucial for sustaining the star's lifecycle and stability.
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 are the three inner layers of a star?
The three inner layers of a star, specifically in the context of a typical main-sequence star like the Sun, are the core, radiative zone, and convective zone. The core is the innermost layer where nuclear fusion occurs, producing energy. Surrounding the core is the radiative zone, where energy is transferred outward through radiation. The outer layer, the convective zone, allows for convective currents that transport energy to the star's surface.
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.
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.
