Home computer found a rare pulsar

By having their own home computers in the spare time to deal with astronomical data, 3 "civilian

scientists" Fortunately, discovered a rare pulsar. Fengyun now named pulsar PSR J2007 2722, is a rapidly

spinning neutron star, it can be a rotation within a second 41 weeks, the pulsar probably originated in a

particular type of supernova, or stellar explosion . The discoverers were three couples in the United

States and Germany, Calvin Daniel Gebhardt, although their jobs are and astronomy do not have any

relationship, but the help of the Einstein @ Home distributed computing (also called voluntary basis) the

project, they completed the generally only be made by the astronomers found. Volunteers participating in

the project will need to download a small screensaver program, and their contribution to the computer idle

time out to download from the Internet for processing scientific data.

Einstein @ Home project in 2005 (World of Physics) was founded in the beginning of the University of

Wisconsin Milwaukee, main purpose is to analyze LIGO (Laser Interferometer Gravitational Wave Observatory)

of observational data to find direct evidence of the existence of gravitational waves, the project runs for

four years later (in 2009, International Year of Astronomy) was added to find the content of pulsar

research, new research projects of the United States through Puerto Rico's Arecibo Observatory in radio

astronomy data obtained to search for new pulsars, and this new pulsar was discovered more than a year to

run the sub after the first time. Side with the words of the project, the project's long-term objective

remains to find gravitational waves, but in the short run, if we can find a year How many pieces of new

pulsars, both for the large number of volunteers, or for the astronomers who will be the a very interesting

thing.

In fact, there is another one this time by the British and Russian volunteers discovered pulsars, the

reason why no official announcement, because the project side of the volunteers found the results to

initial recognition, also need to contact the Observatory of the results of the actual Observation

verification, validation will be officially announced after the adoption.
