List of binary central stars

Design. Name Remarks
005-08.1 Hf 2-2 Close binary nucleus, orbital period 0.399 days.
009+10.1 A 41 Close binary nucleus, orbital period 0.113 days.
017-21.1 A 65 Close binary nucleus, orbital period 1.00 days.
045+24.1 K 1-14 On the POSS a pair of stars separated by 9.1 arcsec
    is in the centre of the nebula. The actual nucleus
    is a star lying 2.4 arcsec southwest of the brighter
    POSS star; it is a probable physical pair
    (component d=0.36 arcsec, p.a.=242 deg).
053-03.1 A 63 Close binary nucleus, eclipsing binary, orbital period
    0.465 days. The CS is a possible physical pair
    (component d=2.82 arcsec, p.a.=94 deg).
055+16.1 A 46 Close binary nucleus, eclipsing binary, orbital period
    0.472 days.
093+05.2 NGC 7008 The CS is a probable physical pair (component
    d=0.42 arcsec, p.a.=241 deg).
118-74.1 NGC 246 The CS is a physical pair (component d=3.81 arcsec,
    p.a.=130.3 deg).
130-10.1 NGC 650-1 The CS is a doubtful physical pair. The companion
    itself is almost certainly a physical system
    (d=0.16 arcsec).
136+05.1 HEFE 1 Close binary nucleus, orbital period 0.582 days.
144+65.1 BE UMa Close binary nucleus, eclipsing binary, orbital period
    2.29 days.
158+17.1 PuWe 1 The CS is a doubtful physical pair. The component
    itself is a close pair (d=0.6).
197+17.1 NGC 2392 The CS is a possible physical pair (component
    d=2.65 arcsec, p.a.=213 deg).
206-40.1 NGC 1535 The CS is a probable physical pair (component
    d=1.04 arcsec, p.a.=334 deg).
208+33.1 A 30 The CS is a possible physical pair (component
    d=5.25 arcsec, p.a.=144 deg).
215+03.1 NGC 2346 Close binary nucleus, orbital period 15.99 days.
215-30.1 A 7 The CS is a possible physical pair (component
    d=0.91 arcsec, p.a.=250 deg).
217+14.1 A 24 The CS is prob. an optical double (component
    d=3.33 arcsec, p.a.=159 deg).
219+31.1 A 31 The CS is a probable physical pair (component
    d=0.26 arcsec, p.a.=242 deg).
228-22.1 DeHt 1 LoTr 1. Close binary nucleus, orbital period unknown.
238+34.1 A 33 The CS is probably a physical pair (component
    d=1.82 arcsec, p.a.=209 deg).
239+13.1 NGC 2610 The CS is a possible physical pair (component
    d=0.61 arcsec, p.a.=277 deg).
253+10.1 K 1-2 Close binary nucleus, orbital period 0.676 days.
272+12.1 NGC 3132 The CS is probably a physical pair (component
    d=1.71 arcsec, p.a.=47 deg).
283+25.1 K 1-22 The CS is a probable physical pair (component
    d=0.35 arcsec, p.a.=218 deg).
283+09.1* ESO-215-04 Close binary nucleus, orbital period 0.357 days.
286-29.1 K 1-27 The CS is a probable physical pair (component
    d=0.56 arcsec, p.a.=315 deg).
303+40.1 A 35 Close binary nucleus, orbital period unknown.
311+02.2 SuWt 2 Close binary nucleus, orbital period 2.45 days.
329+02.1 Sp 1 Close binary nucleus, orbital period 2.91 days.
329-02.2 Mz 2 The CS is a probable physical pair (component
    d=0.28 arcsec, p.a.=218 deg).
335-03.1 HtTr 4 Close binary nucleus, orbital period 1.74 days.
339+88.1 LoTr 5 Close binary nucleus, orbital period unknown.
342-14.1 Sp 3 The CS is a probable physical pair (component
    d=0.31 arcsec, p.a.=42 deg).
345+00.1 IC 4637 The CS is a possible physical pair (component
    d=2.42 arcsec, p.a.=330 deg).
