Stellar Populations of Bulges and Disks: New Insights from Near-IR Colours
arXiv:astro-ph/9509131 · doi:10.1007/978-3-540-49739-4_7
Abstract
Colours of spiral galaxies generally are affected by the underlying old stellar population, younger stars, and extinction by dust. Old and young populations generally can be disentangled using a combination of blue and near-infrared colours. Extinction effects are very hard to take into account, except for galaxies with special orientations. In this paper we give some results of one of the first studies of galactic bulges and disks in various optical and near-infrared bands, and its implications for the stellar populations of spirals.
