II - NGC 4111 and NGC 4762 Tsikoudi, V. Abstract Observations of the luminosity distributions and structures of the edge-on lenticular galaxies NGC 4111 and NGC 4762 are discussed. Photometric observations, when decomposed into contributing luminosity components, reveal in both galaxies the presence of (1) a spheroidal luminosity component due to the nuclear bulge, which is fit by a fourth root luminosity law and contributes about 43% of the galactic light; (2) a prominent lens which exhibits a Gaussian distribution; (3) an exponential luminosity component in the outer regions due to a thin disk and envelope; and (4) additional weaker light contributions along the galactic plane. Specific structural features are also found in each galaxy, including a luminosity dip possibly indicative of an absorption ring in the equatorial plane of NGC 4111 and a low luminosity gradient region possibly describing a weak spiral arm in NGC 4762 Publication: The Astrophysical Journal Supplement Series Pub Date: July 1980 DOI: 10.1086/190672 Bibcode: 1980ApJS...43..365T Keywords: Astronomical Photometry; Galactic Nuclei; Galactic Structure; Isophotes; Lenticular Bodies; Astronomical Models; Galactic Bulge; Luminosity; Normal Density Functions; Astrophysics full text sources ADS | data products NED (7)
