A sortable table of post-CE binary PNe. Click on the header to resort!
Key:
Irr: Irradiation/reflection effect
Ecl: Eclipsing
Ell: Ellipsoidal modulation
DB: Doppler beaming
SB1: Single-lined spectroscopic binary
SB2: Double-lined spectroscopic binary
C: Composite spectrum
B: Bipolar
E: Elliptical
I: Irregular
MS: Multiple shells
* denotes variability reported but not conclusively binary in origin
** denotes that the object was published as a binary but has since been listed as uncertain and in need of further study by Miszalski et al. (2011)
