J/AZh/71/706   BV photometry of galactic nuclei (Silchenko, 1994)

Photometrically Distinct Nuclei in Elliptical and Early-Type Disk Galaxies. Silchenko O.K. <Astron. Zh. 71, 706 (1994)> =1994AZh....71..706S
ADC_Keywords: Galaxies, photometry ; Morphology Description: Using all data in the literature on multiaperture photometry in B and V bands for 237 galaxies, a list of candidates for galaxies with chemically distinct nuclei is compiled. Twenty-five to 50 percent of galaxies with morphological types from E to Sb are found to be such candidates. File Summary:
