Star’s surface gravity
(Preview)
A Brighter Method for Measuring the Surface Gravity of Distant Stars 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 stars surface gravity is one of the key proper...

WX Ursa Majoris
(Preview)
Imagine if your living room zoomed from a comfy 70 degrees to 3,000. In less time than it usually takes to boil an egg. Well, a star did the equivalent - it went from 5,000 degrees Fahrenheit to 30,000 degrees in less than three minutes. And got 15 times brighter in the process. [url=http://www.scienti...
