What else can I help you with?
Which are hotter white dwarfs or red giants?
red giants
Are white dwarfs older then red giants?
yes they are
Are giants hotter than white dwarfs?
No, white dwarfs are much hotter than giants. Giants are stars in the later stages of their evolution, while white dwarfs are the remnants of dead stars that have exhausted their nuclear fuel. White dwarfs can have surface temperatures in the tens of thousands of degrees Kelvin, while giants have lower surface temperatures.
Are red Giants hotter or cooler than white dwarfs?
Red giants are generally cooler than white dwarfs. While red giants have surface temperatures ranging from about 2,200 to 5,000 Kelvin, white dwarfs can reach temperatures of 5,000 to over 100,000 Kelvin. This temperature difference is due to the distinct stages of stellar evolution that these types of stars represent. Red giants are in a later stage of life, while white dwarfs are the remnants of stars that have exhausted their nuclear fuel.
When medium mass stars collapse from red giants to white dwarfs they are also called?
planetary nebulae
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.
Is the surface temperature of white dwarfs higher or lower than red super giants?
Yes dwarf has higher temperature
Is this true Intermediate mass stars expand in red giants and then become part of a supernova?
No. Intermediate mass stars will evolve into Red Giants and then to White Dwarfs. See related questions for more information.
Are blue giants and red dwarfs alike?
Blue giants and red dwarfs are both types of stars, but they are quite different. Blue giants are massive and hot stars that shine brightly, while red dwarfs are smaller, cooler stars that emit a fainter light. Blue giants are more short-lived and evolve faster compared to red dwarfs, which have much longer lifespans.
What are the four categories of the h-r diagram?
The four categorys are main sequence, white dwarfs, red gaint, and super giants.
Do red dwarfs and red giants have similar brightness?
no.they varry in brightness
What are the three extra groups of the H-R diagram?
The three extra groups on the H-R diagram are white dwarfs, red giants, and supergiants. These groups represent stars in different stages of their evolution based on their luminosity and temperature. White dwarfs are small, hot stars near the end of their life cycle, red giants are large, cool stars in the later stages of their life cycle, and supergiants are massive, luminous stars.
