What is the difference between brown dwarfs and Jupiter?
Brown dwarfs are more massive than the planet Jupiter.
What type of star has a high temperature and low luminosity in the HR diagram?
White dwarfs.
What type of star has a high temperature and high luminosity in the HR diagram?
White dwarfs.
Is a red giant the coldest star?
No. Red giants have temperatures comparable to those of red dwarfs. Even cooler are brown dwarfs, which are objects that are in the intermediate range between planets and stars.
What temperature are red stars?
Red stars are normally known as red dwarfs and their color does not mean that they are the hottest star. It's temperature is only about 3,500 Kelvin.
What is the difference between brown dwarfs and Jupiter?
Brown dwarfs are more massive than the planet Jupiter.
Do brown dwarfs orbit Mars?
no
What is a white dwarfs temperature?
it's cool
Is this true or false brown dwarfs white dwarfs and neutron stars are all kept from collapsing by degeneracy pressure?
True.
Is a brown dwarf bigger than the sun?
No Brown Dwarfs are too small to be considerred a star.
A dying star shrinks to this?
Dying stars eventually shrink into white dwarfs (which as they age eventually become red dwarfs and then brown dwarfs - but this takes an extremely long time).
What classification of stars has the lowest surface temperature?
Black dwarfs have the lowest surface temperature.
What stars are cool and dim?
Brown dwarfs are failed stars, so they don't count. Red dwarfs are the kings when it comes to dimness
How are brown dwarfs like Jovian planets?
Both of them have the same mass which is 13MJ Edit : As far as I know brown dwarfs have much more mass than Jupiter, and that's the biggest of the Jovian planets.
Very small stars that are usually old and running out fuel are called?
Those are dwarf stars, which start out as white dwarfs and as they (very slowly) cool, become red dwarfs and eventually brown dwarfs.
How does the brown dwarf make light and heat?
Brown dwarfs are heated primarily due to the compression of their interiors and are hot enough to glow. Some the the more massive brown dwarfs may also fuse deuterium, an isotope of hydrogen, for a short period after they form.
Are giants hotter than white dwarfs?
Red giants are not hotter than white dwarfs. While red giants are much larger and burn more fuel, white dwarfs burn at a higher temperature.
