High-resolution CN spectroscopy of small-scale solar magnetic features
Abstract
High-resolution spectroscopic observations of small-scale magnetic elements in the solar photosphere were carried out in the spectral region 387.5388.4 nm with the 1-m Swedish Solar Telescope (SST). This part of the spectrum covers not only the violet CN band-head, but also contains some lines of the CH molecule. The analysis of the line-core intensity contrasts of the CN and CH lines in bright points (BPs) yielded that on average the BPs appear brighter, thus providing a higher rms contrast, in the CN than in the CH lines in the same spectral band.
