Before a star becomes a red giant, it typically undergoes a process of hydrogen fusion in its core, where hydrogen is converted into helium. As the hydrogen supply depletes, the core contracts under gravity, leading to increased temperature and pressure, which triggers the fusion of helium and other heavier elements in shells around the core. This process causes the outer layers of the star to expand and cool, transforming it into a red giant. The star's luminosity increases significantly during this phase, as it moves off the main sequence in the Hertzsprung-Russell diagram.
What else can I help you with?
Which types of star has low temperature and high luminosity?
A red giant star.
The next stage of life for the sun in about 5 billion years is?
It will become a red giant. However, the Sun will gradually emit more and more energy before that, and it is believed that long before it turns into a red giant - in "only" 1/2 or 1 billion years - it will become too hot for life as we know it to survive on Earth.It will become a red giant.

How long will the sun be a red giant before it transitions into a white dwarf?

Are red giants main sequence stars?
yes before it dies it becomes a red giant
Which types of star has low temperature and high luminosity?
A red giant star.
Is a red giant the same as a giant?
yes but its red
What is the last element a red super giant produces before a supernova explosion?
It is iron.
What stage occurs before a red giant?
Before a star becomes a red giant, it goes through the stage of being a main sequence star, where nuclear fusion in its core converts hydrogen into helium, releasing energy in the form of light and heat.
What will the sun become before it dies?
Red Giant, at which time it will engulf Mercury, Venus, and Earth.
