The Intermediate Polars

Welcome to the Intermediate Polar Home Page, Version 2!

Graph of orbital period plotted against spin period for 64
          Intermediate Polars

Sixty-four of seventy-one 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 system V2400 Oph, Diamonds for the propeller systems AE Aqr and LAMOST J024048.51+195226.9, and 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 2021 of IPs and IP candidates, updated on 2021 December 30.
