The fastest spinning white dwarf has recently been confirmed by a group of researchers from University of Warwick.
The discovered White dwarf is said to complete a full rotation once every 25 seconds.
The particular white dwarf is a rare example of magnetic propeller system. The white dwarf is involved in pulling gaseous plasma from companion star.
In the last 70 years, it is only the second magnetic propeller white dwarf that has been identified, thanks to advanced powerful and sensitive instruments.
The particular white dwarf has been named LAMOST J024048.51+195226.9 or J0240+1952. One rotation on J0240+1952 is a mere 25 seconds compared to 24 hours on Earth.
This speed displayed by the newly discovered white dwarf is faster than the confirmed white dwarf with the most comparable spin rate.
The white dwarf is said to be the size of Earth but is 200,000 times more massive. It pulls plasma materials from its companion star.
The plasma is pulled from the companion star and is being pushed into space at around 3,000 kilometres per second.
White dwarfs are a category of stars that have utilized all the hydrogen present in them for generating energy.
They are at the final stage of evolution for low and medium-mass stars. They are highly dense with low size.
After exhausting all reserve energy, the white dwarf becomes a cold and inert stellar remnant, which is called a black dwarf.
