Webb24 apr. 2024 · Red giants and white dwarfs are both stages in the life cycle of stars that are anywhere from half the size of the Earth's sun to 10 times as large. Both red giants and white dwarfs occur at the end of the star's life, and they are relatively tame in comparison to what some larger stars do when they die. Previous Stages Webb30 juni 2024 · Most intriguingly, though, Caiazzo and her colleagues found the white dwarf was exceedingly small, just slightly bigger than the Moon at 4,300 kilometers (2,700 miles) across. And because more massive white dwarfs are more compact, the small size suggests this is also the most massive white dwarf known.

These objects contain even more material than the sun, but they are only about 10 miles across -- the size of a city. A teaspoon of neutron star material would weigh 4 billion tons!
WebbStars like our Sun leave behind white dwarfs: Earth-size remnants of the original star’s core. More massive stars explode as supernovas, while their cores collapse into neutron stars: ultra-dense, fast-spinning spheres made of the same ingredients as the nucleus of an atom. At least some neutron stars are pulsars, which produce powerful beams ... WebbThe Chandrasekhar limit (/ tʃ ʌ n d r ə ˈ s eɪ k ər /) is the maximum mass of a stable white dwarf star.The currently accepted value of the Chandrasekhar limit is about 1.4 M ☉ (2.765 × 10 30 kg). White dwarfs resist gravitational collapse primarily through electron degeneracy pressure, compared to main sequence stars, which resist collapse through …
WebbScientists call this kind of stellar remnant a white dwarf. A white dwarf is usually Earth-size but hundreds of thousands of times more massive. A teaspoon of its material would weigh more than a pickup truck. A white dwarf produces no new heat of its own, so it gradually cools over billions of years.
