A white dwarf is the last stage of 97% of star evolution.
A white dwarf will eventually cool down, and become a "black dwarf". Black dwarves are not expected to exist yet; to cool down to that level, it would take longer than the current age of the Universe.
That's called a white dwarf.

give out energy
A huge amount. As a rough comparison: Main sequence size a beach ball, white dwarf size a marble. The white dwarf, though is millions of times denser than it's main sequence parent.
When a red giant evolves into a white dwarf, most of its mass is lost during the outer envelope's expulsion, which occurs in the form of stellar winds and planetary nebulae. The core, which remains, is primarily composed of carbon and oxygen and is what ultimately forms the white dwarf. This process significantly reduces the star's mass, with only the dense core remaining as the white dwarf.
A white dwarf is the remnant of a star that has lost most of it mass. When it is formed it is very hot indeed but, as it now has insufficient mas to carry on fusion, it begins to cool down. For objects as massive as stars, even dwarfs, this cooling down takes a long time but eventually a white dwarf will cool down completely and become a black dwarf. Red dwarfs are never very hot as they have barely sufficient mass to effect fusion so don't do it very vigorously. However the fact that they go about their fusion slowly means they can maintain their meager temperatures for a long long time indeed. Some red dwarfs are older than the calculated age of the universe. (which is an interesting paradox) a nova What this person^^^^^ is really trying to say is that : The hottest star is white dwarf.
Thermal (heat) energy can only be converted partially into other types of energy. The remainder is "lost" for many practical purposes.
Lost in a room
A star formed after a red giant has lost mass from its surface is known as a white dwarf. As the red giant sheds its outer layers, the core remains, which is hot and dense, primarily composed of carbon and oxygen. Over time, this core cools and dims, eventually becoming a cold, dark object if it does not accumulate more mass. White dwarfs represent the final evolutionary stage of low to medium mass stars, marking the end of their nuclear fusion processes.
If the sun were to run out of fuel, it would eventually expand into a red giant, consuming Mercury and Venus, and possibly Earth. After this phase, it would shed its outer layers to become a planetary nebula, leaving behind its core as a white dwarf. The white dwarf would slowly cool and fade away over billions of years.
ATP is formed when one of the three energy systems creates the lost high energy bond (that was lost in the production of energy in the muscle contraction) between the 2nd and 3rd inorganic phosphate molecule. when the bond is broken to create a contraction, adenosine triphosphate turns into adenosine diphosphate. and the cycle starts over again.hope that helped
Rumpelstiltskin is the name of the dwarf in the German fairy tale who lost a wager with a queen when she guessed his name.
