Solar Activity and Cloud Opacity Variations: A Modulated Cosmic-Ray Ionization Model
David Marsden, Richard E. Lingenfelter
The observed correlation between global low cloud amount and the flux of high energy cosmic rays supports the idea that ionization plays a crucial role in tropospheric cloud format…
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…
Correlations Between Spectral Properties and Spin-Down Rate in Soft Gamma-Ray Repeaters and Anomalous X-ray Pulsars
D. Marsden, N. E. White
Anomalous x-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs) are x-ray sources with unusual properties distinguishing them from both rotation-powered and most accretion-power…
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…
Does Pulsar B1757--24 Have a Fallback Disk?
D. Marsden, R. E. Lingenfelter, R. E. Rothschild
Radio pulsars are thought to spin-down primarily due to torque from magnetic dipole radiation (MDR) emitted by the time-varying stellar magnetic field as the star rotates. This ass…
