In its next main stage of stellar evolution, the Sun is expected to enter the red giant phase. As it exhausts hydrogen in its core, the core will contract and heat up, causing the outer layers to expand significantly. This expansion will ultimately engulf the inner planets, including Mercury and Venus, and possibly Earth. Eventually, the Sun will shed its outer layers, leaving behind a white dwarf surrounded by a planetary nebula.
What else can I help you with?
Which stage in stellar evolution is the longest?
The longest stage of stellar evolution is the main sequence phase.
What current stage of stellar evolution is altair?
Main Sequence
What stage of stellar evolution is the sun experiencing at this time?
Our Sun is currently on the Main Sequence stage of it's evolution.
What is the main sequence stage?
The main sequence stage is a point in the stellar evolution of stars in the universe at which every star converts hydrogen into helium in its cores and releases huge amounts of energy.
Why giants are not in the main sequence on the H-R diagram?
Because there not that hot
Are most stars in our galaxy found in the main sequence?
Yes, the majority of stars in our galaxy, including our Sun, are found in the main sequence stage of their life cycle. The main sequence is a phase where stars are fusing hydrogen into helium in their cores, which is the most common stage of stellar evolution.
What current stage of stellar evolution is Sirius?
Sirius consists of two stars.Sirius A is a main-sequence star with about two solar masses.Sirius B is a white dwarf with about one solar mass. During its main-sequence, it's estimated to have been around five solar masses.
Name an example of a main sequence?
The Sun is a main sequence star, which is currently fusing hydrogen into helium in its core to produce energy. This stage of stellar evolution is characterized by stable fusion reactions that enable stars to maintain a balance between inward gravitational forces and outward radiation pressure.
Which stage of stellar evolution does combined hydrogen fusion and helium fusion cause a star's outer shell to expand?
Main Sequence - star is stable because of Hydrostatic Equilibrium. Fusing Hydrogen to Helium in core. Stars spends about 90% lifetime as main sequence.This is were I found the answer - http://www.maa.mhn.de/Scholar/star_evol.html
How can star clusters confirm astronomers' theories of stellar evolution?
Star clusters are collections of same-age stars that remain intact for billions of years. When plotted on a H-R diagram, a cutoff point of stars leaving the main sequence and massive stars further evolved are shown, confirming the theory of stellar evolution.
What occurs that causes a main sequence star to lose its equilibrium and move on to the next stage in its evolution?
This happens when a main sequence star uses up all of its fuel and swells. Next stage: Red Giant.
How would you arrange this in order red giant white dwarf and main sequence and why?
The order of stellar evolution is typically: main sequence, red giant, and then white dwarf. Stars spend the majority of their life on the main sequence, where they fuse hydrogen into helium. As they exhaust their hydrogen, they expand into red giants. After shedding their outer layers, the remaining core becomes a white dwarf, which is the final stage of a low to medium mass star.
