Main sequence stars, like the Sun, fuse hydrogen into helium in their cores, maintaining a stable balance between gravitational collapse and nuclear fusion. In contrast, red giant stars have exhausted hydrogen in their cores and have expanded significantly, fusing helium and other heavier elements in shells around the core. This results in a cooler surface temperature, giving red giants their characteristic reddish hue, while main sequence stars typically have a hotter, brighter appearance. Additionally, red giants are much larger and more luminous than their main sequence counterparts.
What else can I help you with?
How would you arrange this in order red giant white dwarf and main sequence?
The correct order of these stellar evolutionary stages is main sequence, red giant, white dwarf. A star begins its life on the main sequence where it fuses hydrogen into helium. As it runs out of fuel, it expands into a red giant before shedding its outer layers and collapsing into a white dwarf.
Why are not giant stars in the main sequence on the H-R diagram?
Because there not that hot
What is the main sequence of the red giant?
The main sequence of a red giant refers to the phase in a star's life cycle prior to its expansion into a red giant. During the main sequence, a star fuses hydrogen into helium in its core, generating energy that counteracts gravitational collapse. Once the hydrogen is depleted, the core contracts and heats up, leading to the outer layers expanding and cooling, which transforms the star into a red giant. Thus, the main sequence is characterized by stable hydrogen burning, while the red giant phase marks the transition to helium burning and further stellar evolution.
What is the main source of energy of a star as it grows in size to becomes a red giant?
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.
What are the stages of the sun's life cycle?
The sun's life cycle includes the stages of formation, main-sequence, red giant, and white dwarf. It is currently in the main-sequence stage, where it fuses hydrogen into helium in its core. Eventually, it will expand into a red giant before shedding its outer layers and becoming a white dwarf.
What order does a nebula occur and becomes a main sequence star and then a giant?
main sequence,giant then nebula
Does a red main sequence star have fusion?
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.
What is the step after main sequence in a stars life?
After the main sequence, a star becomes a red giant.
Is a red giant star considered to be a main sequence star?
No. Red giants are not on the main sequence.
What comes after the main sequence stage?
red giant
How would you arrange this in order red giant white dwarf and main sequence?
The correct order of these stellar evolutionary stages is main sequence, red giant, white dwarf. A star begins its life on the main sequence where it fuses hydrogen into helium. As it runs out of fuel, it expands into a red giant before shedding its outer layers and collapsing into a white dwarf.
What is difference between intermediate mass star and main sequence stars?
i don't think so
What element is the main fuel for main sequence stars for red giant?
Main sequence star: hydrogen-1. Red giants: helium-4.
What is the difference between sequence diagram and communication diagram?
The main difference between communication diagrams and sequence diagrams is that sequence diagrams are good at showing sequential logic but not that good at giving you a "big picture view" whereas communication diagrams are the exact opposite
What category does a star belong in Main sequence star white dwarf red giant neutron star?
None of those is a main sequence star.
What is the brightest star white dwarf nova red giant or main sequence?
Red giant is the largest and the brightest.
Why are not giant stars in the main sequence on the H-R diagram?
Because there not that hot
