Influence of NLTE effects in Fe I lines on inverted atmosphere II. 6301 A and 6302 A lines formed in 3DNLTE
H. N. Smitha, R. Holzreuter, M. van Noort +1
This paper forms the second part of our study on how the neglect of NLTE conditions in the formation of Fe I 6301.5 A and the 6302.5 A lines influences the atmosphere obtained by i…
The influence of NLTE effects in Fe I lines on an inverted atmosphere I. 6301 A and 6302 A lines formed in 1D NLTE
H. N. Smitha, R. Holzreuter, M. van Noort +1
Ultraviolet over-ionisation of iron atoms in the solar atmosphere leads to deviations in their level populations from the Saha-Boltzmann statistics. This causes their line profiles…
Observations of solar chromospheric heating at sub-arcsec spatial resolution
H. N. Smitha, L. P. Chitta, T. Wiegelmann +1
A wide variety of phenomena such as gentle but persistent brightening, dynamic slender features (~100 km), and compact (~1'') ultraviolet (UV) bursts are associated with the heatin…
Probing photospheric magnetic fields with new spectral line pairs
H. N. Smitha, S. K. Solanki
The magnetic line ratio (MLR) method has been extensively used in the measurement of photospheric magnetic field strength. It was devised for the neutral iron line pair at 5247.1 A…
