Every atom of our bodies has been part of a star. In this lively and
compact introduction, astrophysicist Andrew King reveals how the laws of
physics force stars to evolve, driving them through successive stages of
maturity before their inevitable and sometimes spectacular deaths, to
end as remnants such as black holes. The book shows how we know what
stars are made of, how gravity forces stars like the Sun to shine by
transmuting hydrogen into helium in their centers, and why this stage is
so long-lived and stable. Eventually the star ends its life in one of
just three ways, and much of its enriched chemical content is blasted
into space in its death throes. Every dead star is far smaller and
denser than when it began, and we see how astronomers can detect these
stellar corpses as pulsars and black holes and other exotic objects.
King also shows how astronomers now use stars to measure properties of
the Universe, such as its expansion. Finally, the book asks how it is
that stars
form in the first place, and how they re-form out of the debris left by
stars already dead. These birth events must also be what made planets,
not only in our solar system, but around a large fraction of all
stars.
