Edexcel GCSE Astronomy Topic 14 Stellar evolution overview quiz quiz

The outward push of electron degeneracy pressure in the core

The strong magnetic field threading through the whole star

The steady outflow of particles in the solar wind

The outward radiation pressure from nuclear fusion

A white dwarf

A black hole

A neutron star

A supernova

A violent supernova explosion of the core

A planetary nebula

A swollen red supergiant phase

A collapse into a dense neutron star

Ongoing nuclear fusion still running in its core

Neutron degeneracy pressure from packed neutrons

Electron degeneracy pressure

Outward radiation pressure from steady fusion

A white dwarf

A planetary nebula

A red giant

A neutron star

Neutron degeneracy pressure

Electron degeneracy pressure

Radiation pressure

Nothing

The largest mass that any single star is ever allowed to have anywhere in the whole Universe

The maximum mass electron degeneracy pressure can support (about 1.4 solar masses)

The least mass a cloud of gas needs before nuclear fusion can ever begin

The physical size of the event horizon surrounding a typical black hole

A planetary nebula

A nova only

A supernova

A solar flare

By pointing a powerful optical telescope straight at it to view a dark round disc

By measuring the steady visible light that the black hole gives off

By identifying the particular colour the black hole glows on the sky

By its gravitational effect on a companion and X-rays from infalling gas

It is not massive enough; it ends as a planetary nebula and white dwarf

Its core runs far too hot for the violent supernova reaction to ever start

It has no hydrogen or any other fuel left for fusion to carry on burning

It lies much too far away from us for a supernova to occur out there

The red giant stage

The main sequence

The white dwarf stage

The supernova
