Finding hints of gravitational waves in the stars

Scientists have shown how gravitational waves - invisible ripples in the fabric of space and time that propagate through the universe - might be "seen" by looking at the stars. The new model proposes that a star that oscillates at the same frequency as a gravitational wave will absorb energy from that wave and brighten, an overlooked prediction of Einstein's 1916 theory of general relativity. The study, which was published today in a Letter to the journal Monthly Notices of the Royal Astronomica...
