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.
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)
Giants supergiants white dwarfs have left the main sequence?
Yes, all those types of stars have left the main sequence.
How do giants stars differ from main sequences stars?
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.
Which of the following luminosity classes refers to stars on the main sequence?
The basic luminosity classes are: I for supergiants, III for giants, and V for main-sequence stars.
Are most stars giants?
No, most stars are not giants. The group with more stars is Main Sequence Stars.
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.
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.

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.
On a Hertzsprung-Russel diagram red giants and supergiants are positioned?
above the main-sequence stars
What is the scientific name for dying stars?
Red Giants. Stars not on the main sequence
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 is the general size of a main sequence?
It can have many different sizes. Only the largest giants are no longer main sequence stars.
Are main sequence stars older than white dwarfs?
no
Giants supergiants white dwarfs have left the main sequence?
Yes, all those types of stars have left the main sequence.
