What else can I help you with?
Stage where the star swells?
The stage where a star swells into a red giant is called the red giant phase, typically occurring when a star runs out of hydrogen fuel in its core and starts to fuse helium in its shell. During this phase, the star expands and cools, turning redder in color due to its lower surface temperature.
Which phase of life cycle of a star at its end?
super giant.
Is the biggest star in the world the red giant?
The answer to this question is yes. It can vary, but not very much. Yet, the red giant is the coolest star.
Is the blue giant star the hottest star Why?
Cygnus ob2 no.12, a hyper star is & also the biggest.
What type of star is a Enif?
It is a star that has entered the super-giant phase. Its stellar classification is K2 1b.
What is the phase that occurs after a main sequence star?
After its main sequence phase, a star like the Sun will enter the red giant phase where it expands and becomes cooler. Subsequently, it may evolve into a planetary nebula and eventually form a white dwarf.
What do medium stars in the red giant phase become?
A star that is in it's teenage years(medium star) isn't a red giant until it's last years.
What goes through a red giant phase?
A typical star, as it gets older. This should happen to our Sun, eventually. When I say "typical star" I mean apart from the very numerous "red dwarf" stars.
When does the dying phase of a massive star begin?
The dying phase of a massive star begins when it runs out of usable hydrogen that it can convert to helium. Once it becomes a red giant, it slowly dies out.
Is the sun classified as a Red Giant Star?
No. The Sun is a main-sequence star. It will not be a red giant for another 5 billion years.(see related link for an image of what the Sun would look like in its red giant phase
Is a star more stable in the main sequence phase or in the giant phase?
A star is generally more stable during its main sequence phase. In this phase, it achieves a balance between the gravitational forces pulling inward and the nuclear fusion reactions pushing outward, allowing for a long, stable period of energy production. In contrast, during the giant phase, the star undergoes significant changes in its core and outer layers, leading to instability and variability in brightness. Thus, the main sequence phase is characterized by a more stable and predictable state.
What fuses during the red giant phase?
During the red giant phase, hydrogen fusion occurs in the shell surrounding the helium core. The core is no longer fusing hydrogen, as it has already converted most of its hydrogen into helium. This causes the outer layers of the star to expand and cool, leading to the red giant phase.
