A question for Chris and Rassillon.
Hi at all!!! (on italian: "un saluto a tutti!!!)
I have loaded psr1257+12 in my directory Celestia, with the executable 1.2.5 -3.
Veeeeeeeery beeeeest, Rasillon… (aspect with anxiety the file of age carinae… and already the image is wonderful!!!..)
I also have the file psr1257.stc:
# PSR 1257+12
300002 {
RA 13.0027
Dec 12.6667
Distance 2630
SpectralType "Q"
AppMag 18
}
Do I now wonder me: considered that a pulsar quickly rotates on herself, as I can modify the file .stc in such way to be seen to turn it?

The stc itself cannot be modified to reflect a higher rotation...
btw grab the update psr1257fix.zip located below in my signature...The Right Ascention is in degrees instead of hours...
Now when you bring this up a question comes to mind for anyone in general...Pulsars appear to flash or pulse correct? Or is the dimmer/brighter method solely reliant upon the jets? Do the jets rotate to face us at some point?
L'italiano:
la STC in se non pu? essere modificato per riflettere un'pi? alta rotazione...
a proposito l'aggiornamento psr1257fix.zip situato sotto nella mia firma... il Ascention di destra ? nei gradi anzich? le ore... Ora in cui portate questo su una domanda viene alla mente per chiunque in generale... pulsars sembra esporre a flash o pulsare corretto? O ? il metodo di dimmer/brighter solamente fiducioso sui getti? I getti ruotano per affrontarli ad un certo punto?

I'm trying to teach the cavemen how to play scrabble, its uphill work. The only word they know is Uhh and they dont know how to spell it!
Yes, the visible (and radio and xray) pulses are due to the radiation coming from the jets as they rotate through our field of view.
