Einstein@home discovers a rare pulsar

[MeteorWayne]

For more than a year, Einstein@Home has been using about
one-third of the available computer time to search for radio
pulsars in data from the Arecibo Observatory. I'm happy to report
that we found our first radio pulsar last month: PSR J2007+2722.
It is still not sure, but this appears to be a rare type of object
called a Disrupted Recycled Pulsar. The discovery was published
on-line by the journal Science, on Thursday August 12th.

Congratulations to our volunteers Chris and Helen Colvin (Ames, Iowa,
USA) and Daniel Gebhardt (Universitaet Mainz, Musikinformatik, German),
whose computers discovered the pulsar with the highest significance!

Further details of this first Einstein@Home discovery may be found
in the main news item posted on the Einstein@Home web site, at
http://einstein.phys.uwm.edu/ . You can also use Google News
and similar searches, with keywords like 'pulsar' or 'J2007+2722'
or 'Einstein@Home' to find recent news articles about the
discovery, in English, German, French, Spanish, Russian and other
languages.

So far, Einstein@Home has only analyzed about half of the Arecibo data
set. Due to improvements in the instrumentation, the more recent data
is better-quality than the older data, so I am sure there are other
interesting objects to be discovered!

"Einstein@Home is a program that uses your computer's idle time to search for gravitational waves from spinning neutron stars (also called pulsars) using data from the LIGO gravitational wave detector. Learn about this search at einsteinathome.org, Einstein Online and in our S3 report.

Einstein@Home also searches for radio pulsars in binary systems, using data from the Arecibo Observatory in Puerto Rico. Read more about this search here. "

I was wondering about this kind of Pulsar...

"PSR J2007+2722. It is still not sure, but this appears to be a rare type of object called a Disrupted Recycled Pulsar."

According to the website they think that it was part of a binary system and that it was "spun up" and possibly had its magnetic field altered by material falling onto it from its companion. The companion star presumably went supernova and the pair separated. They must have been quite close if material was passing between them. I realize that the surface area of the neutron star is tiny but could there be any effect on it from being that close to a super nova? I'm wondering mostly about the neutrinos which make up most the output of the SN. I have heard that a neutron star is one of the few things dense enough to stop neutrinos so at that distance it's going to get quite a blast of them!
I'm assuming that the answer will be that the neutron star will get warmed up by some teeny tiny barley perceptible amount.
