76 mas bispectrum speckle interferometry of IRC+10216
with the Russian SAO 6 m telescope:
Evidence for a clumpy shell structure

	==>
K-band speckle interferograms of the carbon star IRC+10216 recorded with the Russian 6 m telescope in a night of approximately 1.5 arcsec (bad) seeing.		First K-band image of the carbon star IRC+10216 with 76 mas resolution. This diffraction-limited image was reconstructed from the 6 m telescope speckle data shown on the left side (total number 800) using the bispectrum speckle interferometry. method. The image shows that the dust shell of IRC+10216 is extremely clumpy. The separation of the two brightest objects is approximately 210 milli-arcsec ~ 34 AU ~ 10 stellar radii (see A&A 333, L51, 1998 for more details).
