Fred Hoyle Medal and Prize

History
In 2008 Council decided to establish the Fred Hoyle Medal and Prize.

The physicist behind the medal
Fred Hoyle was an English astrophysicist who developed the theory of stellar nucleosynthesis, which describes how elements heavier than helium are produced by nuclear reactions within stars. Hoyle directed Cambridge University’s Institute for Astronomy for six years, and was a fellow of the Royal Society and a winner of its Royal Medal as well as the Royal Astronomical Society’s Gold Medal.

Terms

Cecilia Payne-Gaposchkin Medal and Prize

History
In 2008 Council decided to establish the Cecelia Payne-Gaposchkin Medal and Prize.

The physicist behind the medal
Cecilia Payne-Gaposchkin was a British-American astrophysicist who, in the course of her PhD studies on stellar spectra, discovered that stars are composed overwhelmingly of hydrogen and helium, in contrast to the prevailing view that the chemical makeup of the stars was much the same as that on Earth .She thereby established that hydrogen is the most abundant element in the universe. After her doctorate, Payne-Gaposchkin carried out observations of more than three million variable stars, with her data being used to determine stellar evolution.

Terms
The award shall be made for distinguished contributions to plasma, solar or space physics. The medal will be silver and will be accompanied by a prize of £1,000 and a certificate.
