Abstract: |
CVs could be surrounded by cold material that has condensed out of the ejecta from the compact binary. The strong braking resulting from tidal interactions between such a circumbinary (CB) disc and the red dwarf might explain several puzzles in our current understanding of CV evolution. The thermal emission from CB discs is expected to peak in the mid-IR. We report on a survey of the mid-IR emission from 8 CVs. AE Aqr and SS Cyg are detected above 5 μm but the observed rapid variability makes CB material unlikely in both cases. We discuss the upper limits on CB discs resulting from this study and the prospects for their detection. |
