A red supergiant has the hottest core because it has exhausted its nuclear fuel in the core, causing the core to contract and heat up due to gravitational compression. This increased temperature is what leads the outer layers of the star to expand and cool, giving the star its red color.
What else can I help you with?
Does a red supergiant have the hottest core?
No, a red supergiant does not have the hottest core. Instead, blue supergiant stars have the hottest cores, with temperatures reaching up to tens of thousands of degrees Kelvin. Red supergiants have cooler cores in comparison.
Does a red giant start have fusion occurring in its core?
Yes, a red giant is a stage in the life cycle of a star where fusion reactions are occurring in its core. The core of a red giant star typically consists of helium undergoing fusion into heavier elements like carbon and oxygen.
What color is a red super giant?
red
What is the difference between a red supergiant and a red giant?
A red supergiant is the largest type of star by volume, but not by mass. It is also one of the"coolest" active stars. These stars have fused most of their hydrogen to helium, and pressure from its core have swelled its size, to between 200 and 800 times the diameter of our Sun. Since the mass has not increased with the volume, the star's average density is comparatively low.
Which of the following types of star is the most luminous red supergiant red main sequence star white dwarf or yellow main sequence star?
Red Super Giants have already passed their main sequence stage and are on the way to death. Luminosity also depends on how close the star is to us. But for arguments sake we will say that they are all the same distance away. The brightest would be a Yellow Main sequence. Next would be a Red Super Giant, the faintest of all is the white dwarf this is the remaining core of a Red Giant Star, Not Super Giant, that has died. It is very dense, very faint about the size of Earth

When a star collapses does it get bigger?
that depends on how large the red or super red giant was. if it was a super red giant that is 1000X larger than a red giant. it will become a black hole

What color is a red super giant?
red
Who are the Super Novas?
Super Nova is a explosion of a red giant or a red supergiant.
What is a red giants core called?
A red giant's core is called a helium core. This is because as a red giant forms, the core of the star contracts and heats up, causing hydrogen fusion to transition to helium fusion.
How is the red-giant formed?
A red giant forms when a star runs out of hydrogen fuel at its core and starts fusing hydrogen in a shell around the core the core. This causes the star to expand and cool.
What is an expanding star after exhausting its hydrogen fuel called?
An expanding star after exhausting its hydrogen fuel is called a red giant. This stage occurs when the core contracts and heats up, causing the outer layers of the star to expand and cool, giving it a red color.
What is the gigantic explosion of a red giant?
Technically the explosion of a Red giant is not called a Supernova as the mass of the star is not great enough. However the explosion from a Red Super Giant can be called a supernova. A normal Red giant doesn't actually explode, the core just collapses again to cause a white dwarf and the outer layers are ejected to form planetary Nebulae.
How would you know if the sun burned out?
it would be red , bigger , and and grow until it is a red giant , a red super giant , or a hyper-giant
