Importance of Angle-dependent Partial Frequency Redistribution in Hyperfine Structure Transitions Under Incomplete Paschen-Back Effect Regime
K. N. Nagendra, K. Sowmya, M. Sampoorna +2
Angle-frequency coupling in scattering of polarized light on atoms is represented by the angle-dependent (AD) partial frequency redistribution (PRD) matrices. There are several lin…
Resonance Line Polarization in Spherically Symmetric Moving Media: a Parametric Study
A. Megha, M. Sampoorna, K. N. Nagendra +2
In the present paper we consider the problem of resonance line polarization formed in the spherically symmetric expanding atmospheres. For the solution of the concerned polarized t…
Polarized Line Formation in Arbitrary Strength Magnetic Fields: the case of a two-level atom with hyperfine structure splitting
M. Sampoorna, K. N. Nagendra, K. Sowmya +2
Quantum interference effects together with partial frequency redistribution (PFR) in line scattering produce subtle signatures in the so called Second Solar Spectrum (the linearly…
Polarized scattering of light for arbitrary magnetic fields with level-crossings from the combination of hyperfine and fine structure splittings
K. Sowmya, K. N. Nagendra, M. Sampoorna +1
Interference between magnetic substates of the hyperfine structure states belonging to different fine structure states of the same term influences the polarization for some of the…
Polarized scattering with Paschen-Back effect, hyperfine structure, and partial frequency redistribution in magnetized stellar atmospheres
K. Sowmya, K. N. Nagendra, J. O. Stenflo +1
-state interference significantly modifies the polarization produced by scattering processes in the solar atmosphere. Its signature in the emergent Stokes spectrum in the absenc…
Blend lines in the polarized spectrum of the Sun
K. Sowmya, K. N. Nagendra, M. Sampoorna
Blend lines form an integral part of the theoretical analysis and modeling of the polarized spectrum of the Sun. Their interaction with other spectral lines needs to be explored an…
