Neutron stars warp space-time, U-M astronomers observe

08-28-2007 · EurekAlert!

ANN ARBOR, Mich. -- Einstein's predicted distortion of space-time occurs around neutron stars, University of Michigan astronomers and others have observed. Using European and Japanese/NASA X-ray observatory satellites, teams of researchers have pioneered a groundbreaking technique for determining the properties of these ultradense objects.

  1. Chandra discovers cosmic cannonball
    11-28-2007 · EurekAlert!
    One of the fastest moving stars ever seen has been discovered with NASA's Chandra X-ray Observatory. This cosmic cannonball is challenging theories to explain its blistering speed.Astronomers used Chandra to observe a neutron star, known as RX J0822-4300, over a period of about five years. During that span, three Chandra observations clearly show the neutron star moving away from the center of the Puppis A supernova remnant at over 3 million miles per hour.

  4. Hubble yields direct proof of stellar sorting in a globular cluster
    10-24-2006 · EurekAlert!
    A seven-year study with the NASA/ESA Hubble Space Telescope has provided astronomers with the best observational evidence yet that globular clusters sort out stars according to their mass. Heavier stars slow down and sink to the cluster's core, while lighter stars pick up speed and move across the cluster to its periphery. This process, called "mass segregation," has long been suspected for globular star clusters, but has never before been directly seen in action.

  5. New stars shed light on the past
    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.

  6. Stars caught in bizarre death-dance
    09-13-2007 · Massachusetts Institute of Technology (MIT)
    MIT astronomers played a key role in discovering what NASA calls one of the most bizarre objects in space: a star "skeleton" of very low mass that is orbiting and being slowly consumed by a pulsar, that is itself spinning faster than a kitchen blender.

  7. A galactic fossil
    05-10-2007 · EurekAlert!
    How old are the oldest stars? Using ESO's VLT, astronomers recently measured the age of a star located in our galaxy. The star, a real fossil, is found to be 13.2 billion years old, not very far from the 13.7 billion years age of the universe. The star, HE 1523-0901, was clearly born at the dawn of time.

  8. Possible closest neutron star to Earth found
    08-20-2007 · EurekAlert!
    Astronomers have identified an object that is likely one of the closest neutron stars to Earth -- and possibly the closest. The object, located in the constellation Ursa Minor, is nicknamed Calvera, after the villain in the movie "The Magnificent Seven." If confirmed, it would be only the eighth known "isolated neutron star" -- a neutron star that does not have an associated supernova remnant, binary companion or radio pulsations.
