Robert C. Kennicutt, Jr reviews the star formation rates (SFRs) in galaxies along the Hubble sequence, focusing on the patterns in star formation properties and their implications for galaxy evolution. He discusses the diagnostic methods used to measure SFRs, including integrated colors and spectra, ultraviolet continuum, recombination lines, forbidden lines, and far-infrared continuum. These methods help determine SFRs by tracing the young stellar population and its evolution. The SFRs are influenced by factors such as gas content, mass, bar structure, and dynamical environment. The review highlights the importance of understanding the physical processes driving star formation and the evolution of galaxies. It also discusses the variations in SFRs among different galaxy types and the implications for galaxy evolution. The SFRs are measured using various techniques, including Hα, UV continuum, and FIR data, which provide insights into the star formation history and the overall evolution of galaxies. The review emphasizes the need for accurate SFR calibrations and the importance of considering factors such as extinction, IMF, and star formation history when interpreting SFR data. The findings show that SFRs vary significantly across the Hubble sequence, with different mechanisms driving star formation in different galaxy types. The review concludes with a discussion of the physical regulation of SFRs and future prospects in this field.Robert C.
