Spectral evidence for jets from accreting millisecond X-ray pulsars (2009)
Russell, D.M., Fender, R.P., Jonker, P., Maitra, D.
Transient radio emission from X-ray binaries is associated with synchrotron emission from collimated jets that escape the system, and accreting millisecond X-ray pulsars (AMXPs) are no exception....
