"Bolometric" refers to the measurement of the total energy output of a source of radiation, including all wavelengths of electromagnetic radiation. This term is commonly used in fields like astronomy and physics to assess the brightness of stars and other celestial objects. A bolometer is the instrument used to measure this energy, detecting the heat produced by absorbed radiation. In astronomy, bolometric measurements help scientists understand the luminosity and temperature of stars, including those in the Milky Way galaxy. By analyzing bolometric data, researchers can gain insights into stellar evolution and the physical properties of various astronomical phenomena, such as supernovae and black holes.
