10 Dec 1995 | Journal: | Astron.Astrophys.Suppl.Ser. 117 (1996) 417 | Subject: | astro-ph | Affiliation: | Obs. de Lyon), F. Simien (Obs. de Lyon), and G.A. Mamon (Inst. d’Astrophys. de Paris | Abstract: | We present $K’$-band surface photometry of a sample of 31 inclined Sa-Scd galaxies, together with additional $J$- and $H$-band data for four of them. In this first paper of a series, profiles are presented, together with global and isophotal parameters. Our profiles are compared to similar $B$, $R$ and $I$ data collected from other sources. Three galaxies exhibit previously unknown small bars in their center, while in five others, such bars may also be present. Four objects present a narrow elongated feature in their center aligned with their major axis, which could be an inward extension of the disk. A few galaxies display very thin spiral arms. Color-color diagrams indicate that the extinction inside the four galaxies for which we have $JHK’$ images is limited to $A_V < 2$. | Source: | arXiv, astro-ph/9601048 | Services: | Forum | Review | PDF | Favorites |
