Infrared variability in pre-Main Sequence stars. The study: “Near-infrared time-series photometry in the field of Cygnus OB2 association II. Mapping the variability of candidate members” of J. Roquette (University of Exeter/ ICEx – UFMG) recently appeared on A&A
Pre-Main Sequence stars are young stars whose nuclei are still not hot enough to trigger the thermonuclear reactions that will produce energy for the rest of their existence. Some of these stars are called “T Tauri”, and they are surrounded by a protoplanetary disk made of gas and dust, where planetary systems may form. T Tauri stars were classified for
