A&A special feature: XMM-Newton deciphers the magnetic physics around forming stars
05-31-2007 · EurekAlert!Astronomy & Astrophysics is publishing a special feature this week dedicated to the XMM-Newton extended survey of the Taurus molecular cloud. One of the main results is the identification of unusual physical processes not known before in forming stars. These unprecedented observations suggest that the gas streams falling down onto the forming star and the jets being ejected from it both play major roles in the production of X-rays.

- XMM-Newton reveals X-rays from gas streams around young stars
05-31-2007 · European Space Agency (ESA)
XMM-Newton has surveyed nearly two hundred stars under formation to reveal, contrary to expectations, how streams of matter fall onto the young stars' magnetic atmospheres and radiate X-rays.

- XMM-Newton gives new insight into neutron stars
01-08-2008 · European Space Agency (ESA)
XMM-Newton has given astronomers and physics a valuable new insight into the most exotic stars in the Universe. Known as neutron stars, the composition of these extremely dense stellar objects has always been something of a puzzle. Now, XMM-Newton has revealed that they almost certainly resemble over-sized atomic nuclei.

- The missing link in the evolution of magnetic cataclysmic stars?
09-14-2007 · EurekAlert!
An international team of astronomers might have discovered the missing link in the evolution of the so-called magnetic cataclysmic variable stars. They determined the spin and orbital periods of the binary star Paloma. They found that the Paloma system has a weird way of rotating that fills the gap between two classes of magnetic cataclysmic stars. Their results will soon be published in Astronomy & Astrophysics.

01-08-2007 · EurekAlert!
A new image from the Hubble Space Telescope shows N90, one of the star-forming regions in the Small Magellanic Cloud. The rich populations of infant stars found here enable astronomers to examine star forming processes in an environment that is very different from that in our own Milky Way.

- X-ray evidence supports possible new class of supernova
01-04-2007 · EurekAlert!
Evidence for a significant new class of supernova has been found with NASA's Chandra X-ray Observatory and the European Space Agency's XMM-Newton. These results strengthen the case for a population of stars that evolve rapidly and are destroyed by thermonuclear explosions. Such "prompt" supernovas could be valuable tools for probing the early history of the cosmos.
