"The search for planets outside our Solar System – exoplanets – is one of the
most rapidly growing fields in astronomy. Over the past few decades, more than
5,000 exoplanets have been detected and astronomers now estimate that on
average there is at least one planet per star in our galaxy.
Many current research efforts aim at detecting Earth-like planets suitable for
life. These endeavours focus on so-called “main sequence” stars like our Sun –
stars which are powered by fusing hydrogen atoms into helium in their cores,
and remain stable for billions of years. More than 90% of all known exoplanets
so far have been detected around main-sequence stars.
As part of an international team of astronomers, we studied a star that looks
much like our Sun will in billions of years’ time, and found it has a planet
which by all rights it should have devoured. In research published today in
Nature, we lay out the puzzle of this planet’s existence – and propose some
possible solutions."
