Infrared variability is a research area that focuses on studying changes in the intensity of infrared radiation emitted by celestial objects over time. This includes variations in the brightness and spectral characteristics of infrared radiation emitted by stars, galaxies, and other astronomical bodies. Researchers study these variations to better understand the physical processes and environments of these objects, such as stellar activity, dust formation, and the presence of exoplanets. Detecting and analyzing infrared variability can provide valuable insights into the nature and evolution of celestial objects, as well as the conditions in their surrounding environments.
