A novel investigation of the small-scale magnetic activity of the quiet Sun via the Hanle effect in the Sr I 4607 Å line
T. del Pino Alemán, J. Trujillo Bueno, J. Štěpán +1
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…
Evershed flow observed in neutral and singly ionized iron lines
E. Khomenko, M. Collados, N. Shchukina +1
The amplitudes of the Evershed flow are measured using pairs of carefully selected FeI and FeII spectral lines located close in wavelength and registered simultaneously. A sunspot…
Spectropolarimetric diagnostics of unresolved magnetic fields in the quiet solar photosphere
Nataliya Shchukina, Javier Trujillo Bueno
A few years before the Hinode space telescope was launched, an investigation based on the Hanle effect in atomic and molecular lines indicated that the bulk of the quiet solar phot…
Determining the Magnetization of the Quiet Sun Photosphere from the Hanle Effect and Surface Dynamo Simulations
Nataliya Shchukina, Javier Trujillo Bueno
The bulk of the quiet solar photosphere is thought to be significantly magnetized, due to the ubiquitous presence of a tangled magnetic field at subresolution scales with an averag…
Solar granulation from photosphere to low chromosphere observed in BaII 4554 A line
R. Kostik, E. Khomenko, N. Shchukina
The purpose of this paper is to characterize the statistical properties of solar granulation in the photosphere and low chromosphere up to 650 km. We use velocity and intensity var…
Solar BaII 4554 A line as Doppler diagnostics: NLTE analysis in 3D hydrodynamical model
N. G. Shchukina, V. L. Olshevsky, E. Khomenko
The aim of this paper is to analyse the validity of the Dopplergram and lambda-meter techniques for the Doppler diagnostics of solar photospheric velocities using the BaII 4554 A l…
