XMM-Newton Observes the Intrabinary Shock of PSR J1959+2048
D. Kandel, Roger W. Romani, Hongjun An
In a multi-orbit (100 ks) exposure of the original black widow pulsar, PSR J1959+2048, we measure the strong orbital modulation caused by intrabinary shoc…
PSR J1810+1744: Companion Darkening and a Precise High Neutron Star Mass
Roger W. Romani, D. Kandel, Alexei V. Filippenko +2
Keck-telescope spectrophotometry of the companion of PSR J1810+1744 shows a flat, but asymmetric light-curve maximum and a deep, narrow minimum. The maximum indicates strong gravit…
Discovery of a Gamma-ray Black Widow Pulsar by GPU-accelerated Einstein@Home
L. Nieder, C. J. Clark, D. Kandel +39
We report the discovery of 1.97 ms period gamma-ray pulsations from the 75 minute orbital-period binary pulsar now named PSR J1653-0158. The associated Fermi Large Area Telescope g…
On the vanishing orbital X-ray variability of the eclipsing binary millisecond pulsar 47 Tuc W
Pavan R. Hebbar, Craig O. Heinke, D. Kandel +2
Redback millisecond pulsars (MSPs) typically show pronounced orbital variability in their X-ray emission due to our changing view of the intrabinary shock (IBS) between the pulsar…
Heated Poles on the Companion of Redback PSR J23390533
D. Kandel, Roger W. Romani, Alexei V. Filippenko +2
We analyze photometry and spectra of the "redback" millisecond pulsar binary J23390533. These observations include new measurements from Keck and GROND, as well as archival meas…
Atmospheric Circulation on Black Widow Companions
D. Kandel, Roger W. Romani
We present a model for atmospheric wind circulation in binary millisecond pulsar (MSP) companions, showing how the optical light curve (LC) and radial velocities (RV) are sensitive…
