Scientific paper

We present the results from the SIR inversion of spectropolarimetric data acquired with the IBIS (Interferometric BIdimensional Spectrometer) instrument at the NSO Dunn Solar Telescope, Sacramento Peak (NM, USA). The inversion analysis is performed on Stokes I and V profiles measured in the two FeI visible lines at 630 nm over a (~ 40 x 40 Mm) quiet Sun portion, for a time interval of 53 minutes. The noise level for Stokes V profiles is 0.003 the continuum intensity. The high spatial resolution of the G-band images combined with the inversion results helps to interpret the physical properties of G-band bright points, i.e., their field strength and magnetic filling factor. Moreover, the time span of the observation allows to investigate the variation of such physical quantities with time. More in detail, we focus on the analysis of three distinct processes, namely the coalescence, fragmentation, and cancellation of G-band bright points.
