The Intermediate Polars
Welcome to the Intermediate Polar Home Page, Version 2!
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.
