The core contracts, raising the temperature and increasing the size of the region of hydrogen shell-burning.
The next step in its life is to become a "red giant" star.
I am pretty sure it becomes a giant if I'm not mistaken.
in some cases it becomes a red giant then later progresses into a wight dwarf . according to the main sequence . in other cases it becomes a red supergiant then a supernova takes place leading the dying star to become either a neutron star or a black hole according to the main sequence
The North Star (Polaris) does not get brighter as you travel north. It appears to be the same brightness regardless of your location on Earth. What changes is its position in the sky relative to your viewpoint as you move northward.
A main sequence star burns hydrogen to helium. Once a main sequence star exhausts all of the hydrogen, it begins to expand and burn helium causing if to become a red giant.
As the bulb becomes brighter, more current flows through the filament, increasing its temperature. This increase in temperature causes the filament to glow more intensely, resulting in a brighter light output.
DNA Sequence = 5tacttcttcaagact-3 RNA Sequence = 3'-AUGAAGAAGUUCUGA-5'You just switch 5' and 3'T becomes AA becomes UC becomes GG becomes CThere should be no Ts in an RNA sequence.
A comet becomes brighter as it approaches the sun. It's at that time that the heat from the sun begins to boil the ice present in the comet, and its tail becomes visible as it moves, leaving a trail behind it that scatters light, making it appear brighter.
After the main sequence, a star becomes a red giant.
main sequence,giant then nebula
The bulb gets brighter because the filament is getting hotter. If the filament's temperature gets too high it will melt at some point and fall apart. The current will stop flowing and the bulb will "blow".
As the bulb becomes brighter, the temperature of the filament increases. This is due to the increased flow of electricity through the filament, causing it to heat up and emit more light. The relationship between brightness and temperature is direct - the brighter the bulb, the hotter the filament.
A Main Sequence star.
A red main sequence star would be a red dwarf or a branch red giant. To be on the main sequence, you have to have hydrogen nuclear fusion.
The sound becomes brighter when strings are plucked and only seems to be louder.
Low mass stars become brighter after depleting hydrogen because all of the hydrogen in the core has been fused into helium. Once this happens, hydrogen fusion begins in the outer layers, which causes more heat and light generation.
yes before it dies it becomes a red giant
