What else can I help you with?
Which star is cooler and more brighter than the sun?
There are a lot of these. They are mainly the "Red Giant" and "Red Supergiant" stars.
How many times brighter is a cepheid variable of absolute magniture -3 than a white dwarf of absolute magnitude of 7?
That is a difference of ten magitudes so the factor in brightness is 10,000.
What is the magnitude of a white dwarf?
The magnitude of a white dwarf can vary significantly, typically ranging from about 10 to 15 in absolute magnitude. This variation depends on factors such as its mass, temperature, and composition. For example, hotter and more massive white dwarfs tend to have lower absolute magnitudes, making them appear brighter. However, their apparent magnitude can differ based on their distance from Earth.
Is rigel a dwarf star?
No Rigel is a huge, blue supergiant of spectral class B8 Ia, Rigel has an intrinsic brightness about 40,000 times as luminous as that of the sun.
What is the absolute magnitude of procyon?
2.65. It has a white dwarf companion of about 13
Is rigel a dwarf planet or a supergiant?
it is a dwarf planet the size of a supergiant.

Is Betelgeuse a dwarf planet?
No, Betelgeuse is not a dwarf planet. Betelgeuse is a supergiant star located in the constellation of Orion. It is one of the largest and most luminous stars known in our galaxy.
What is the absolute value of a white-dwarf?
Depends on the white dwarf in question. They can have a myriad of absolute magnitude values.
Does a red giant or a white dwarf star have greater absolute?
Red giants have typical absolute magnitudes which are 10-15 magnitudes below white dwarfs, which means that the red giants are 10,000-1,000,000 times brighter, after due allowance for distance.
Why do some dwarf stars appear brighter than giant stars?
Because they are closer or actually brighter.

How do you explain what the differences are between main sequence stars white dwarf stars and supergiant stars?
A star on "main sequence" is a period in a stars evolution.A white dwarf is a stellar remainA supergiant star is the size of a very big star.So they are completely different and not even related.
Have absolute magnitudes of ones or less?
dwarf stars -Sydney-
What kind of stars form red giants?
when Dwarf Stars run out of hydrogen they form Red Giant stars, then from that they become White dwarf stars when the outer layers shed, forming a planetary nebula.when giant stars or supergiant stars run out of hydrogen they form red supergiant stars
