Does this neutron star have an accretion disk?:

There are 15 known Accreting Millisecond X-Ray Pulsars (AMXPs), and IGR J11014-6103 is not among them. Other sources suggest that the jets are the result of a rapidly rotating highly magnetic pulsar, but make no mention of an accretion disk.

Thank you. Does your third link work?

Where does the material in this jet originate from - the neutron star itself?

They make no mention of where the material for the jets originate, only that it is being generated by a rapidly rotating and highly magnetized neutron star. They have been able to confirm the helical pattern of the jets, and the trailing material perpendicular to the jets are the result of the bow-shock due to the star's supersonic velocity, but they fall short of stating whether or not the neutron star has an accretion disk. Considering they are not able to fully reproduce their observations in the models they have created suggests that they are either missing information, do not completely understand the nature of this neutron star, or both.

I'm not sure what happened with the last URL I posted. Here it is again:

Maybe it’s a not untypical young neutron star that is a good observation candidate because its not obscured by explosion debris or an accretion cloud. Likely its had the jet since it was formed, and if there is no accretion cloud it means the jet material is coming directly from the star: There’s an unclear theory about “rotation powered” jets that doesn’t make great sense …… somehow a spinning magnetic field is supposed to suck up material from the poles at >0.8c?
