| Abstract: |
We introduce a near-IR monitoring campaign of the Local Group spiral
galaxy M 33, carried out with the UK IR Telescope (UKIRT). The
pulsating giant stars are identified and their distributions are used
to derive the star formation rate as a function of age. We here present
the star formation history for the central square kiloparsec. These
stars are also important dust factories; we measure their dust
production rates from a combination of our data with Spitzer
Space Telescope mid-IR photometry. |
