UV Spectropolarimetry with Polstar: Protoplanetary Disks
John P. Wisniewski, Andrei V. Berdyugin, Svetlana V. Berdyugina +13
Polstar is a proposed NASA MIDEX mission that would feature a high resolution UV spectropolarimeter capable of measure all four Stokes parameters onboard a 60cm telescope. The miss…
Inference of electric currents in the solar photosphere
A. Pastor Yabar, J. M. Borrero, C. Quintero Noda +1
We aim at demonstrating the capabilities of a newly developed method for determining electric currents in the solar photosphere. We employ three-dimensional radiative magneto-hydro…
Highly sensitive search for magnetic fields in white dwarfs using broad-band circular polarimetry
Andrei V. Berdyugin, Vilppu Piirola, Stefano Bagnulo +2
Circular polarisation measurements of white dwarfs of various ages and spectral types are useful to understand the origin and evolution of the magnetic field in degenerate stars. I…
The polarization angle in the wings of Ca i 4227: A new observable for diagnosing unresolved photospheric magnetic fields
Emilia Capozzi, Ernest Alsina Ballester, Luca Belluzzi +1
When observed in quiet regions close to the solar limb, many strong resonance lines show conspicuous linear polarization signals, produced by scattering processes, with extended wi…
Modeling the scattering polarization of the solar Ca i 4227 Å line with angle-dependent partial frequency redistribution
Gioele Janett, Ernest Alsina Ballester, Nuno Guerreiro +4
Context. The correct modeling of the scattering polarization signals observed in several strong resonance lines requires taking partial frequency redistribution (PRD) phenomena int…
A novel fourth-order WENO interpolation technique. A possible new tool designed for radiative transfer
Gioele Janett, Oskar Steiner, Ernest Alsina Ballester +2
Context. Several numerical problems require the interpolation of discrete data that present various types of discontinuities. The radiative transfer is a typical example of such a…
