Category: Brief Article


Several nonlinear techniques have been appplied to intensity oscillations of the chromospheric bright points observed, at the Vacuum Tower Telescope (VTT) of the Sacramento Peak Observatory, a 35-min time sequence spectra in the CaII H line over a quiet region at the center of the solar disk under high spatial, spectral, and temporal resolution. Utilizing multivariate spatial embedding, the correlation integral has been found to be significantly different from the multivariate surrogates. The methods namely, dynamical phase synchronization and the similarity index, to detect nonlinear coupling, have been used and the results have been also statistically compared with multivariate surrogate data.
