[AAVSO LightCurve, 5yr]
GCVS data:
Epoch 2000: ra = 280.082, dec = -22.910
Variability type: *
Spectral type: pec(HDCe)/WC10:
GCVS remarks:
VB A (B 15m pg, 16", 73deg). Very hot hydrogen deficient helium carbon star. By the character of light variation and the spectrum the star is unique. The light curve resembling those of RCB type stars is superimposed by conspicuons irregular and semiregular variations with the mean cycle about 200d [02449, 09824]. The star is surrounded by a nebula the radius of which equals 1". A fainter nebulous envelope is observed up to 7" from the star. Large infrared excess. Spectrum description [02451, 09825]. Probably the star is intermediate between the RCB variables And planetary nebula Wolf-Rayet central stars.
