On the calibration of the Strömgren photometric system for F and G stars. (1994). Revista Mexicana De Astronomía Y Astrofísica, 29(1), 129-136. https://astronomia.unam.mx/journals/rmxaa/article/view/1994rmxaa..29..129n
Abstract
Calibrations of the Str6mgren uvby- system in terms of effective temperature, absolute magnitude and metal-to-hydrogen ratio are reviewed and the accuracy of the derived parameters is estimated. The importance of correcting the photometric indices for interstellar reddening is stressed and duplicity effects are discussed. The need for very accurate values of the stellar atmospheric parameters is demonstrated with some examples from galactic evolution and Big Bang nucleosynthesis theories.Similar Articles
