EINSTEIN@HOME Discovery - Binary Radio Pulsar
08 March, 2011 19:26 CST6CDT(Feb 28, 2011 7:21 PM)
A new preprint reports the second Einstein@Home discovery, of a radio pulsar orbiting a white dwarf star once every 9.4 hours. The pulsar, called J1952+2630, is spinning on its axis 48 times per second. It was discovered in data collected at Arecibo Observatory in 2005 by the PALFA Collaboration. The white-dwarf companion star is unusually massive, and weighs at least 95% as much as our sun. This means that J1952+2630 probably belongs to a rare class of intermediate-mass binary pulsars (five were previously known). Congratulations to the two Einstein@Home participants whose computers found J1952+2630 with the highest significance: Dr. Vitaliy V. Shiryaev (Moscow, Russia) and Stacey Eastham (Darwen, UK)! And a big "thank you" to all Einstein@Home volunteers, whose continuing support makes these exciting discoveries possible. Bruce Allen Director, Einstein@Home
Arecibo PALFA Survey and Einstein@Home:
Binary Pulsar Discovery by Volunteer Computing
(Submitted on 25 Feb 2011)
We report the discovery of the 20.7-ms binary pulsar J1952+2630, made using the distributed computing project Einstein@Home in Pulsar ALFA survey observations with the Arecibo telescope. Follow-up observations with the Arecibo telescope confirm the binary nature of the system. We obtain a circular orbital solution with an orbital period of 9.4 hr, a projected orbital radius of 2.8 lt-s, and a mass function of f = 0.15 solar masses by analysis of spin period measurements. No evidence of orbital eccentricity is apparent; we set a 2-sigma upper limit e < 1.7e-3. The orbital parameters suggest a massive white dwarf companion with a minimum mass of 0.95 solar masses, assuming a pulsar mass of 1.4 solar masses. Most likely, this pulsar belongs to the rare class of intermediate mass binary pulsars. Future timing observations will aim to determine the parameters of this system further, measure relativistic effects, and elucidate the nature of the companion star.

Arecibo Radio Telescope & Welcome to our Team!
24 February, 2011 06:58 CST6CDTThe 305 meter Radio Telescope
"Those who see the Arecibo radio telescope for the first time are astounded by the enormousness of the reflecting surface, or radio mirror. The huge "dish" is 305 m (1000 feet) in diameter, 167 feet deep, and covers an area of about twenty acres. The surface is made of almost 40,000 perforated aluminum panels, each measuring about 3 feet by 6 feet, supported by a network of steel cables strung across the underlying karst sinkhole. It is a spherical (not parabolic) reflector ." - [full article @ naic.edu]

For those of you wondering what the EINSTEIN@HOME Project is:
Einstein@Home uses your computer's idle time to search for weak astrophysical signals from spinning neutron stars (also called pulsars) using data from the LIGO gravitational-wave detectors, the Arecibo radio telescope, and the Fermi gamma-ray satellite. Einstein@Home volunteers have already discovered more than a dozen new neutron stars, and we hope to find many more in the future. Our long-term goal is to make the first direct detections of gravitational-wave emission from spinning neutron stars. Gravitational waves were predicted by Albert Einstein almost a century ago, but have never been directly detected. Such observations would open up a new window on the universe, and usher in a new era in astronomy.My name is Andy Wright - the founder, but really the creator of Team FreeBSD. If you want me to add any links, or have any questions or inclinations for such things related to our group (or to just say hi) - send me an e-mail: einstein@extracted.org or Skype name: extracted

| Einstein@Home volunteers discover three new radio pulsars in Arecibo data |
Einstein@Home volunteers have discovered three new radio pulsars in Arecibo PALFA data -- the eighth, ninth and tenth new radio pulsars found by Einstein@Home volunteers in this data set! Congratulations to:
Further details about these newly-discovered pulsars can be found on this web page, and will be published in due course.
