In fact, Lu Chen did not see it wrong; that phenomenon was indeed a helium flash!
The helium flash is a brief loss of control that occurs during the process of helium undergoing nuclear fusion, and because it is very peculiar, it is called the helium flash!
Under normal circumstances, a helium flash occurs after low-mass stars leave their main-sequence phase, when there has been a large depletion of hydrogen, leading to an accumulation of a significant amount of helium in the core.
Of course, the helium flash also occurred in the quasi-star we have in front of us.
This demonstrates that under certain conditions, white dwarf stars can also produce helium flashes.
As long as the surface of a white dwarf star accretes enough helium, and the temperature on the surface of the white dwarf star is not yet able to support helium fusion, there will naturally not be the thermal pressure from nuclear fusion to counteract gravitational collapse.
