Evolution of Black Widow Pulsars
We consider the evolution of black widow pulsars (BWPs). The large majority of these are members of globular clusters. For minimum companion masses < 0.1M ̄, adiabatic evolution and consequent mass loss under gravitational radiation appear to provide a coherent explanation of all observable properties. We suggest that the group of BWPs with minimum companion masses ∼> 0.1M ̄ are systems relaxing ...
متن کاملBlack widow spider bite.
These two cases illustrate many classical features of latrodectism. A subclinical bite followed by extensive systemic signs and symptoms in a recognizable pattern is strongly suggestive of the diagnosis. Pain and muscle spasms are refractory to standard therapy but are relieved by intravenous calcium. Finally, there should be complete resolution of the symptoms after only one vial of antivenin ...
متن کاملOrbital Evolution of an Accreting Millisecond Pulsar: Witnessing the Banquet of a Black Widow
We have performed a timing analysis of all the four X-ray outbursts from the accreting millisecond pulsar SAX J1808.4−3658 observed so far by the PCA on board RXTE. For each of the outbursts we derived the best-fit value of the time of ascending node passage. We find that these times follow a parabolic trend, which gives an orbital period derivative Ṗorb = (3.40±0.12)×10 −12 s/s, and a refined ...
متن کاملOrbital Evolution of an Accreting Millisecond Pulsar: Witnessing the Banquet of a Hidden Black Widow
We have performed a timing analysis of all the four X-ray outbursts from the accreting millisecond pulsar SAX J1808.4−3658 observed so far by RXTE. For each of the outbursts we have found the local best orbital solution, keeping fixed to their best fit values the orbital period and the a sin i amplitude, and fitting for the time of ascending node passage. Plotting the best-fit values obtained i...
متن کاملHibernation Revived by Weak Magnetic Braking
Cataclysmic variables undergo periodic nova explosions during which a finite mass of material is expelled on a short timescale. The system widens and, as a result, the mass-transfer rate drops. This state of hibernation may account for the variety of cataclysmic variable types observed in systems of similar mass and period. In the light of recent changes to the theory of nova ignition and magne...
