Propeller vs. Magnetar Concepts for SGR/AXPs
Richard E. Rothschild, Richard E. Lingenfelter, David Marsden
Two lines of thought exist as to the nature of Soft Gamma-ray Repeaters (SGRs) and Anomalous X-ray Pulsars (AXPs). On the one hand,we have neutron stars with super-critical magneti…

Fossil Disks and Propellor Spindown of SGR/AXPs
Richard E. Rothschild, David Marsden, Richard E. Lingenfelter
We have shown that the interstellar media which surround the progenitors of SGRs and AXPs were unusually dense compared to the environments around most young radio pulsars. This en…

Resolution of the Age Discrepancies in Pulsar/SNR Associations
D. Marsden, R. E. Lingenfelter, R. E. Rothschild
Pulsars associated with supernova remnants (SNRs) are valuable because they provide constraints on the mechanism(s) of pulsar spin-down. Here we discuss two SNR/pulsar associations…
