A brighter method for measuring the surface gravity of distant stars

Nashville TN (SPX) Aug 23, 2013 – Astronomers have found a clever new way to slice and dice the flickering light from a distant star in a way that reveals the strength of gravity at its surface. That is important because a star’s surface gravity is one of the key properties that astronomers use to calculate a star’s physical properties and assess its evolutionary state. The new technique can also be used to significa … more
