The Physical Universe: An Introduction to Astronomy
The Helium Flash and Descent to the Horizontal Branch The ignition of helium in
the core of a low-mass star, however, occurs under degenerate conditions; so it
lacks the safety-valve feature which characterizes core- hydrogen burning on the
...

Horizons: Exploring the Universe
The higher temperature increases the helium fusion even further, and the result is
a runaway explosion called the helium flash in which, for a few minutes, the core
of a star can generate more energy per second than does an entire galaxy.

Astronomy: The Solar System and Beyond
The higher temperature increases the helium fusion even further, and the result is
a runaway explosion called the helium flash in which, for a few minutes, the core
of a star can generate more energy per second than does an entire galaxy.

Structure and Evolution of Single and Binary Stars
The helium flash typically lasts a few minutes. However, the helium flash goes
almost unnoticed at the stellar surface, since much time is needed before the
energy surplus at the centre reaches the surface of the red giant. When it arrives
at the ...

2. What is the zero age horizontal-branch? The helium flash drastically alters the
interior structure of a globular-cluster star from one characterized by a highly
degenerate helium core and a single energy source, namely, a hydrogen-
burning ...

They may also occur in the outer layers of larger stars in shell flashes. 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 ...
