V1647 Ori - X-raying the beating heart of a newborn star
X-ray observations by ESA's XMM-Newton, NASA's Chandra and Japan's Suzaku space observatories have probed the interior of the dust disc to find a rapidly-rotating star spinning with a period of one day. At 80 per cent the mass of our Sun and with a diameter approximately four times larger, spinning at this rate nears break-up speed for a star of this size.
The data also suggest that matter is accreting onto the stellar surface in two pancake-shaped hotspots located on opposite sides of the star, in which the matter heats up and the high temperature plasma is confined.
