This review by Robert C. Kennicutt, Jr. focuses on the patterns in star formation properties along the Hubble sequence and their implications for understanding galaxy evolution. The author discusses the global star formation rates (SFRs) in galaxies, emphasizing the systematic variations in SFRs and star formation histories across different morphological types. The review covers both disk and nuclear regions of galaxies, using various diagnostic methods to measure SFRs, including integrated colors and spectra, ultraviolet (UV) continua, recombination lines, and far-infrared (FIR) emissions. These methods provide insights into the physical processes driving star formation and the evolution of galaxies. The review also explores the relationship between SFRs and other physical properties such as gas content, mass, bar structure, and dynamical environment. The author highlights the importance of understanding the physical regulation of SFRs and the implications for future research in this field.This review by Robert C.
