WD J005311 is a newly identified white dwarf ( WD ) in a mid-infrared nebula .
The spectroscopic observation indicates the existence of a neon-enriched carbon/oxygen wind with a terminal velocity of v _ { \infty, obs } \sim 16 , 000 km s ^ { -1 } and a mass loss rate of \dot { M } _ { obs } \sim 3.5 \times 10 ^ { -6 } M _ { \odot } yr ^ { -1 } .
Here we consistently explain the properties of WD J005311 using a newly constructed wind solution , where the optically thick outflow is launched from the carbon burning shell on an oxygen-neon core and accelerated by the rotating magnetic field to become supersonic and unbound well below the photosphere .
Our model implies that WD J005311 has a mass of M _ { * } \sim 1.1 \mbox { - } 1.3 M _ { \odot } , a magnetic field of B _ { * } \sim ( 2 \mbox { - } 5 ) \times 10 ^ { 7 } G , and a spin angular frequency of \Omega \sim 0.2 \mbox { - } 0.5 s ^ { -1 } .
The large magnetic field and fast spin support the carbon-oxygen WD merger origin .
WD J005311 will neither explode as a type Ia supernova nor collapse into a neutron star .
If the wind continues to blow another few kyr , WD J005311 will spin down significantly and join to the known sequence of slowly-rotating magnetic WDs .
Otherwise it may appear as a fast-spinning magnetic WD and could be a new high energy source .
