| Abstract: |
We are investigating the hypotheses that bulges of early-type spirals are akin to (and may in fact originally have been) intermediate-luminosity ellipticals while bulges of late-type spirals are formed from dynamical instabilities in their disks. This report discusses the current status of our on-going survey of the stellar populations of the bulges and inner disks of spirals at various points along the Hubble sequence. Absorption-line spectroscopy of the central regions of Sa-Sd spirals will be combined with stellar population models to determine integrated mean ages and metallicities. |
