The White Dwarf Companions of Recycled Pulsars
I review what properties of the white-dwarf companions of recycled pulsars can be inferred from optical observations, and discuss how these can help us understand the characteristics and evolution of these binaries. I focus on spectroscopic observations, describing results obtained recently, and looking forward to what may come.
متن کاملRecycled Pulsars Discovered at High Radio Frequency
We present the timing parameters of nine pulsars discovered in a survey of intermediate Galactic latitudes at 1400 MHz with the Parkes radio telescope. Eight of these pulsars possess small pulse periods and period derivatives thought to be indicative of “recycling”. Six of the pulsars are in circular binary systems, including two with relatively massive white dwarf companions. We discuss the im...
متن کاملUnique White Dwarfs Accompanying Recycled Pulsars
Knowledge of the properties of the white-dwarf companions of radio pulsars can provide unique constraints on the characteristics and evolution of these binaries, as well as on those of its constituents. Many white-dwarf properties can be determined accurately from their spectra, but for the very faint pulsar companions spectroscopy has only become feasible with the advent of large telescopes li...
متن کاملOn the absence of mildly recycled radio pulsars amongst the population of ordinary single radio pulsars
Current scenarios for the evolution of binaries predict that only 1%or less of the single radio pulsars in the galactic disk have been recycled in a binary. The fraction of such pulsars amongst the detected single radio pulsars is smaller than this. For magnetic field strengths B > 1012 G the period vs. magnetic field diagram shows no evidence for injection of pulsars at P ∼ 0.5 s. For magnetic...
متن کاملSpectral Analysis of X-ray Pulsars with the Integral Observatory
We studied spectra for 34 accretion-powered X-ray and one millisecond pulsars that were within the field of view of the INTEGRAL observatory over two years (December 2002–January 2005) of its in-orbit operation and that were detected by its instruments at a statistically significant level (> 8σ in the energy range 18–60 keV). There are seven recently discovered objects of this class among the p...
