The European Solar Telescope
C. Quintero Noda, R. Schlichenmaier, L. R. Bellot Rubio +14
The European Solar Telescope (EST) is a project aimed at studying the magnetic connectivity of the solar atmosphere, from the deep photosphere to the upper chromosphere. Its design…
The role of quantum interference and partial redistribution in the solar Ba II D2 4554 A line
H. N. Smitha, K. N. Nagendra, J. O. Stenflo +1
The Ba II D2 line at 4554 A is a good example, where the F-state interference effects due to the odd isotopes produce polarization profiles, which are very different from those of…
Modeling the quantum interference signatures of the Ba II D2 4554 A line in the second solar spectrum
H. N. Smitha, K. N. Nagendra, J. O. Stenflo +1
Quantum interference effects play a vital role in shaping the linear polarization profiles of solar spectral lines. The Ba II D2 line at 4554 A is a prominent example, where the F-…
Nature of the solar dynamo at small scales
J. O. Stenflo
It is often claimed that there is not only one, but two different types of solar dynamos: the one that is responsible for the appearance of sunspots and the 11-yr cycle, frequently…
Polarized line formation with J-state interference in the presence of magnetic fields: A heuristic treatment of collisional frequency redistribution
H. N. Smitha, K. N. Nagendra, M. Sampoorna +1
An expression for the partial frequency redistribution (PRD) matrix for line scattering in a two-term atom, which includes the J-state interference between its fine structure line…
Polarized line transfer with F-state interference in a non-magnetic medium: Partial frequency redistribution effects in the collisionless regime
H. N. Smitha, K. Sowmya, K. N. Nagendra +2
Quantum interference phenomena manifests itself in several ways in the polarized solar spectrum formed due to coherent scattering processes. One such effect arises due to interfere…
