The Intermediate Polars

Welcome to the Intermediate Polar Home Page, Version 2!

Graph of orbital period plotted against spin period for 47
          Intermediate Polars

Forty seven of forty nine Ironclad or Confirmed IPs are shown above in a Porb-Pspin diagram (see the list sorted by the Porb/Pspin ratio). Symbols: Open Square for the diskless V2400 Oph, Diamond for the propeller AE Aqr, Pluses for double-pulse IPs, Crosses for soft IPs (an overlapping cross/plus for V405 Aur), Circles for the rest. The vertical dashed lines show the approximate location of the period gap, while diagonal lines are for Porb=Pspin (solid) and Porb=10xPspin (dashed). Also see the note on the accretion modes of IPs.

See the full catalog, Version 2014 of IPs and IP candidates, updated on 2014 October 29.
