For a star with less than 1.8 times the mass of the Sun, this will occur in a process called the helium flash.

You said a new equilibrium will be reached, after the helium flash."

Its temperature climbed higher almost daily; the helium flash was close - or might, indeed, already have occurred.

The explosive nature of the helium flash arises from its taking place in degenerate matter.

The helium flash is not directly observable on the surface by electromagnetic radiation.

There is a runaway fusion reaction - a helium flash - lasting no more than seconds.

It will continue to warm, until in thirty or forty years there will be an explosion called the "helium flash."

The general estimate was that Beta Castelli would not reach its helium flash point for another five billion years.

Within a few seconds the core becomes non-degenerate and quickly expands, producing an event called helium flash.

But it's approaching its helium flash point."

Helium flash in the motor?

"Because of the helium flash."

For stellar masses smaller than about 2 M, this new combustion takes place in a highly degenerate matter and proceeds through a helium flash.

'Shell helium flashes' are a similar helium ignition event, although not necessarily dependent on degenerate matter.

When the mass of helium becomes sufficiently large, a helium flash can occur, with runaway fusion causing a nova.

"Won't the action of the birds suppress this helium runaway - the helium flash just as they've suppressed hydrogen fusion, all this time?"

Following the initial announcement, Hilmar Duerbeck et al. published a study investigating the 'possible final helium flash' seen by Sakurai.

Once the degenerate core reaches this temperature, the entire core will begin helium fusion nearly simultaneously in a so-called helium flash.

A helium nova (or helium flash) is a proposed category of nova explosion that lacks hydrogen lines in the spectrum.

Shell helium flashes are a somewhat analogous but much less violent, nonrunaway helium ignition event, taking place in the absence of degenerate matter.

Superwind... The helium flash would blow away half the mass of the Sun, into an expanding shell ballooning outwards at hundreds of miles a second.

After passing through the red giant stage, it underwent the helium flash event and is presently generating energy through the thermonuclear fusion of helium at its core.

A helium flash occurs in these situations because the helium is degenerate, meaning it is supported against gravity by quantum mechanical pressure rather than thermal pressure.

Super-AGB stars develop partially degenerate carbon-oxygen cores that are large enough to ignite carbon in a flash analogous to the earlier helium flash.

A star with mass greater than about 2.25 solar masses starts to burn helium without its core becoming degenerate, and so does not exhibit this type of helium flash.
