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.
Is rigel a dwarf star?
No, Rigel is not a dwarf star. It is a blue supergiant star located in the constellation Orion. It is one of the brightest stars in the sky and is much larger and more luminous than a dwarf star.
What is the color of old stars?
Red (giant, supergiant or dwarf), Blue (supergiant), white (dwarf), blueish white/gamma-ray (neutron star) or produce no light at all (black hole).
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.
Is rigel a dwarf star?
No, Rigel is not a dwarf star. It is a blue supergiant star located in the constellation Orion. It is one of the brightest stars in the sky and is much larger and more luminous than a dwarf star.
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
Is a white dwarf star brighter then a red giant?
No, it is much less bright.
