The density of a white dwarf is?
It varies, but it is several tons per cubic centimeter - i.e., millions of times as dense as water.
How is a white dwarf different form a neutron star?
A neutron star has slightly more mass than a white dwarf. This results in higher gravitational attraction. As a result, in a white dwarf, the star's mass (roughly the mass of the Sun - may vary in different white dwarves) has a diameter of a few thousand kilometers, and a density of a few tonnes per cubic centimeter. The neutron star, on the other hand, has a diameter of only 20-30 kilometers, and a density of millions of tonnes per cubic centimeter. For comparison, water has a density of 1 gram per cubic centimeter, other substances around us have similar densities; so the density of a white dwarf is millions of times the density of water, while a neutron star has billions of times the density of water.
What is the different between white dwarf and a sun?
White dwarves have run out of fuel; therefore they have stopped producing energy, through nuclear fusion. Also, they are very small - smaller than planet Earth, while (for comparison) our Sun has 109 times the diameter of Earth; they are very dense (a cubic centimeter of white dwarf matter has a mass of several tons), and fairly hot - though, since they don't produce energy, they will gradually cool down.
What is the explosion of a dwarf star called?
The explosion of a dwarf star is called a nova or a supernova, depending on the type of dwarf star and the circumstances of the explosion. Novas are less powerful explosions caused by a white dwarf siphoning material from a companion star, while supernovas are much more energetic explosions that can occur in white dwarfs or other types of stars.
What causes a white dwarf supernova?
A white dwarf supernova occurs when a white dwarf star in a binary system accretes material from a companion star, causing it to exceed the Chandrasekhar limit (1.4 solar masses). The core then undergoes a runaway nuclear fusion reaction, leading to a catastrophic explosion that destroys the white dwarf.

How tall does a gala semi dwarf apple tree get?

How much would 1 teaspoon of a white dwarf weigh?
A teaspoon (5ml) of white dwarf material would weigh about 6,500,000 grams or just over 7 metric tons.
Where are most dwarf planet found?
So far most dwarf planets are found in a ring of icy debris beyond the orbit of Neptune known as the "Kuiper Belt." Only one dwarf planet is recognized in the belt of dry material between Mars and Jupiter known as the asteroids. That dwarf is called Ceres.
When does a nova event occurs if a white dwarf accepts material from a nearby?
A nova event occurs when a white dwarf in a binary system accepts material from a nearby companion star, causing a runaway nuclear fusion explosion on the surface of the white dwarf. This explosion results in a sudden increase in brightness that can last for several days to a few weeks.
A teaspoonful of white dwarf material on Earth would weigh?
A teaspoonful of white dwarf material on Earth would weigh millions of tons due to its incredibly dense nature. White dwarfs have masses comparable to the Sun but are compressed into a volume roughly the size of Earth, resulting in an immense weight for even a small amount of material.
