| Abstract: |
Solar fine-scale magnetic features in the lower atmosphere hold the key to
many poorly understood aspects of solar magnetism
at all scales.
High-resolution and high-cadence observations obtained with the New Vacuum
Solar Telescope (NVST) of Fuxian Solar Observatory are used to
investigate the statistical and dynamical behaviors of bright points
(BPs), umbral dots (UDs), and Ellerman bombs (EBs).
The following prominent results are found: (1) greater, brighter, and
rounder BPs are found in regions with stronger magnetic fields; (2) the diameter and
lifetime of UDs show an increasing trend with their brightness, while
their velocity exhibits an inverse trend; (3) some EBs can be heated to
8×104 K, one to two orders of magnitude higher than the enhancement
predicted from models of EBs.
The results of this analysis suggest that the one-meter NVST is a
successful facility for observing the Sun with very high spatial and
temporal resolution, and for acquiring
detailed information on the evolution of the
above-mentioned fine-scale magnetic structures. |
