Inferring Solar Magnetic fields From the Polarization of the Mg II h and k Lines
Hao Li, Tanausú del Pino Alemán, Javier Trujillo Bueno
The polarization of the Mg II h and k lines holds significant diagnostic potential for measuring chromospheric magnetic fields, which are crucial for understanding the physical pro…
Determining the magnetic field of active region plages using the whole CLASP2/2.1 spectral window
David Afonso Delgado, Tanausú del Pino Alemán, Javier Trujillo Bueno +16
The Chromospheric LAyer SpectroPolarimeter missions, CLASP2 and CLASP2.1, demonstrated that the near-UV spectral region between 279.30 and 280.68 nm is suitable for studying the ma…
P-CORONA: A New Tool for Calculating the Intensity and Polarization of Coronal Lines in 3D Models of the Solar Corona
Supriya Hebbur Dayananda, Ángel de Vicente, Tanausú del Pino Alemán +2
The critical need to study the magnetic field in the solar corona is highlighted by recent observational facilities, such as DKIST and Aditya-L1. A powerful tool for probing the ma…
Multi-wavelength spectropolarimetric observations of AR13724 performed by GRIS
C. Quintero Noda, J. C. Trelles Arjona, T. del Pino Alemán +10
Multi-line spectropolarimetric observations allow for the simultaneous inference of the magnetic field at different layers of the solar atmosphere and provide insight into how thes…
Non-Local Thermodynamic Equilibrium inversions of the Si I 10827 A spectral line
C. Quintero Noda, N. G. Shchukina, A. Asensio Ramos +4
Inferring the coupling of different atmospheric layers requires observing spectral lines sensitive to the atmospheric parameters, particularly the magnetic field vector, at various…
The polarization of the solar Ba II D1 line with partial frequency redistribution and its magnetic sensitivity
E. Alsina Ballester, T. del Pino Alemán, J. Trujillo Bueno
We investigate the main physical mechanisms that shape the intensity and polarization of the Ba II D1 line at 4934 angstroms via radiative transfer numerical experiments. We focus…
Magnetic field information in the near-ultraviolet Fe II lines of the CLASP2 space experiment
David Afonso Delgado, Tanausú del Pino Alemán, Javier Trujillo Bueno
We investigate theoretically the circular polarization signals induced by the Zeeman effect in the Fe II lines of the 279.3-280.7 nm spectral range of the CLASP2 space experiment a…
The circular polarization of the Mn I resonance lines around 280 nm for exploring chromospheric magnetism
Tanausú del Pino Alemán, Ernest Alsina Ballester, Javier Trujillo Bueno
We study the circular polarization of the Mn I resonance lines at 279.56, 279.91, and 280.19 nm (hereafter, UV multiplet) by means of radiative transfer modeling. In 2019, the CLAS…
The polarization of the Lyman- lines of H I and He II as a tool for exploring the solar corona
Supriya Hebbur Dayananda, Javier Trujillo Bueno, Ángel de Vicente +1
The near-Earth space weather is driven by the quick release of magnetic free energy in the solar corona. Probing this extremely hot and rarified region of the extended solar atmosp…
On the (mis)interpretation of the scattering polarization signatures in the Ca II 8542 A line through spectral line inversions
Rebecca Centeno, Jaime de la Cruz Rodriguez, Tanausu del Pino Aleman
Scattering polarization tends to dominate the linear polarization signals of the Ca II 8542 A line in weakly magnetized areas ( G), especially when the observing ge…
Long characteristics vs. short characteristics in 3D radiative transfer simulations of polarized radiation
A. de Vicente, T. del Pino Alemán, J. Trujillo Bueno
We compare maps of scattering polarization signals obtained from three-dimensional (3D) radiation transfer calculations in a magneto-convection model of the solar atmosphere using…
Mapping Solar Magnetic Fields from the Photosphere to the Base of the Corona
Ryohko Ishikawa, Javier Trujillo Bueno, Tanausu del Pino Aleman +25
Routine ultraviolet imaging of the Sun's upper atmosphere shows the spectacular manifestation of solar activity; yet we remain blind to its main driver, the magnetic field. Here we…

One of the key research problems in stellar physics is to decipher the small-scale magnetic activity of the quiet solar atmosphere. Recent magneto-convection simulations that accou…
Non coherent continuum scattering as a line polarization mechanism
T. del Pino Alemán, R. Manso Sainz, J. Trujillo Bueno
Line scattering polarization can be strongly affected by Rayleigh scattering by neutral hydrogen and Thompson scattering by free electrons. Often a continuum depolarization results…
