Wave propagation and shock formation in different magnetic structures
Rebecca Centeno, Manuel Collados, Javier Trujillo Bueno
Velocity oscillations "measured" simultaneously at the photosphere and the chromosphere -from time series of spectropolarimetric data in the 10830 A region- of different solar magn…
Channeling 5-min photospheric oscillations into the solar outer atmosphere through small-scale vertical magnetic flux tubes
E. Khomenko, R. Centeno, M. Collados +1
We report two-dimensional MHD simulations which demonstrate that photospheric 5-min oscillations can leak into the chromosphere inside small-scale vertical magnetic flux tubes. The…
Emergence of Small-Scale Magnetic Loops in the Quiet Sun Internetwork
R. Centeno, H. Socas-Navarro, B. Lites +11
We study the emergence of magnetic flux at very small spatial scales (less than 2 arcsec) in the quiet Sun internetwork. To this aim, a time series of spectropolarimetric maps was…
Spicule emission profiles observed in \ion{He}{i} 10830 Å
B. Sánchez-Andrade Nuño, R. Centeno, K. G. Puschmann +3
Off-the-limb observations with high spatial and spectral resolution will help us understand the physical properties of spicules in the solar chromosphere Spectropolarimetric observ…
Evidence for Fine Structure in the Chromospheric Umbral Oscillation
R. Centeno, H. Socas-Navarro, M. Collados +1
Novel spectro-polarimetric observations of the \ion{He}{1} multiplet are used to explore the dynamics of the chromospheric oscillation above sunspot umbrae. The results presented h…
The Hanle and Zeeman Effects in Solar Spicules: A Novel Diagnostic Window on Chromospheric Magnetism
J. Trujillo Bueno, L. Merenda, R. Centeno +2
An attractive diagnostic tool for investigating the magnetism of the solar chromosphere is the observation and theoretical modeling of the Hanle and Zeeman effects in spicules, as…
