No comment but isn't this kinda why we are all here? lol

That is a very fast pulsar.
Does anyone here, know what rotation rates this Einstein program looks at?
What is the window of periods it is searching through?
How do we find out if our WU has uncovered a pulsar, how will be know its period and location?

I'm hoping some killer graphics (planned for the future?) will fill us in on that one.

The nearest I can find out is that once your WU's are done you have to wait till 4 other computers verify your results. Try looking at your account> results view> then click on the work unit id. It shows who else is working on those units. But if you are like me (also with 0's) you will find that they have not sent the WU out to others. So who know when/if we ever will be of use. I have no idea what happens when the "time is up" and the others have not verified the work???

Hello and welcome Dennis!
There definetly has to be a better structured forum, so that this theme-mix will stop ;-)
But, nevertheless (and absolutely no offense intended):
A good manual for Boinc is Paul D. Bucks BOINC Powered Projects Documentation and his FAQ therein.

was saying that they thought they were seeing a pulsar at
3000 Hz.
The interesting thing to me is that before the theories seemed to say that
760Hz was about the max.
(see http://www.freerepublic.com/focus/f-news/939554/posts)
but I guess that is just to be stable.

I didn't look back just now (so let's see how my menory is) but I think it said something about spinning at 3K per second and any more would break it up (not stable)... guess I'll go read it again lol. Since then, I've played 4 games of chess, had a phone interview and updated some software on my box...
EDIT (good thing I went back lol)
"rotating nearly 600 times every second. Most millisecond pulsars hover around the 300 revolutions per second mark, and the fastest spinning pulsar ever detected clocked in at 641 rps.
But even this is far short of the theoretical maximum of around 3,000 revolutions per second. Any faster that this and the object would tear itself apart."

Yes, It is the fastest pulsar so far and my guess is it will spin apart. I wonder if our number crunching would see such things. I am not sure but I think that most of these Ligo and Geo600 things have most of their sensitivities at the low end things ( a few orders of magnitude from 10's to 1000's Hz). I sure hope that this project tells us more about the science here and less about the computer games.
If anyone knows the frequency sensitivites of our searches, please post them.
There has to be someone out there that knows the astronomy, what is really going on in these programs.

HaHA, I'm newer than you! Where is this? TIA.
EDIT: Nevermind, I didn't know you meant from the "Your account" page lol, thx

Good idea Dennis. A spot on the home page would be nice too IMO.
