WebMar 4, 2011 · A new method was developed to estimate the effective temperature, surface gravity, and metallicity of cool stars using only photometric indices in the uvby color system. In a graphical method, T eff and log g were determined for all of the different values of [Fe/H] using model atmosphere grids with respect to (b − y):c 1 and (b − y):m 1 pair indices. WebThe photometric method provides a high temporal means of simultaneously monitoring the fluorescence of intracellular ion-sensitive dyes and the transmembrane voltage or current …

WebPhotometry, from Greek photo- ("light") and -metry ("measure"), is a technique used in astronomy that is concerned with measuring the flux or intensity of light radiated by astronomical objects.

The set of passbands or filters is called a photometric system. The difference in magnitudes found with these filters is called the U−B or B−V color index respectively. In principle, the temperature of a star can be calculated directly from the B−V index, and there are several formulae to make this connection. See more In astronomy, the color index is a simple numerical expression that determines the color of an object, which in the case of a star gives its temperature. The lower the color index, the more blue (or hotter) the object is. … See more • Query for Johnson, H. L. and Morgan, ApJ 117, 313 (1953) • Query for Cousins, A. W.
