Giant stars differ from main sequence stars primarily in size, luminosity, and temperature. While main sequence stars fuse hydrogen into helium in their cores, giants have exhausted their hydrogen and are now fusing heavier elements, leading to increased brightness and larger radii. Additionally, giant stars often have cooler surface temperatures compared to main sequence stars of similar mass due to their expanded size. This results in a distinct position on the Hertzsprung-Russell diagram, where giants occupy the upper regions compared to the more centralized position of main sequence stars.
What else can I help you with?
Name the four main types of stars?
The four types of stars are; Main Sequence, White Swarfs, Red Giants and Super Giants. 90% of stars are in the Main Sequence.
Are main sequence stars older than red giants?
No, red giants are generally older than main sequence stars, as red giants have no hydrogen left for fuel, and burn helium instead. where as Main Sequence stars burn hydrogen for fuel.
What kind of stars are there?
There are various types of stars, such as main sequence stars (like our sun), red giants, white dwarfs, neutron stars, and black holes. These stars differ in size, mass, temperature, and lifespan. They are classified based on their characteristics and the stage of their evolution.
Describe two types of stars that are not on the main sequence-?
Red Giants - although they can be branch main sequence for a while.Brown DwarfsBlack dwarfsWhite dwarfsT-Tauri starsProtostarsNeutron starsPre-main sequence stars (PMS stars)
Do low mass main sequence stars become red super giants?
No. Only massive stars can become supergiants.
Are most stars giants?
No, most stars are not giants. The group with more stars is Main Sequence Stars.

No, red giants are generally older than main sequence stars, as red giants have no hydrogen left for fuel, and burn helium instead. where as Main Sequence stars burn hydrogen for fuel.
What is the scientific name for dying stars?
Red Giants. Stars not on the main sequence
What are featureless galaxies that contain old red main-sequence stars and red giants called?
With red giants and main sequence stars they are not entirely featureless, therefore there is no name for them.
What element is the main fuel for red giants main sequence stars?
Main sequence star: hydrogen-1. Red giants: helium-4.
What red giants element is the main fuel for main sequence stars?
Main sequence star: hydrogen-1. Red giants: helium-4.
On a Hertzsprung-Russel diagram red giants and supergiants are positioned?
above the main-sequence stars

How much farther away are the red giants compared to the main-sequence of stars?
Red giants are a later stadium of main sequence stars, there is no relation between distance and position in the Hertzsprung Russell diagram.
What are Featureless galaxies containing old red main-sequence stars and red giants called?
If they have red stars including giants in, they can't be all that featureless.
