Candidates

Wickramasinghe et al. 1991 suggest non-detection of polarization suggests B < 5 MG. If this is confirmed, then there are quite a few IPs with magnetic fields weaker than known polars, and hence will not evolve into polars. There are a few IPs that will.

Survey and Non-system-specific Modelling

• Stockman et al. 1992: 4-sigma result on AE Aqr, 3-sigma result on FO Aqr, and non-detections of TV Col, YY Dra, DQ Her, EX Hya, GK Per, and AO Psc.

• Wickramasinghe et al. 1991: non-detection of polarized light suggests B < 5 MG
