On the fine structure of the sunspot penumbrae. III The vertical extension of penumbral filaments
J. M. Borrero, S. K. Solanki, A. Lagg +2
In this paper we study the fine structure of the penumbra as inferred from the uncombed model (flux tube embedded in a magnetic surrounding) when applied to penumbral spectropolari…
Solar Site Survey for the Advanced Technology Solar Telecope. I. Analysis of the Seeing Data
H. Socas-Navarro, J. Beckers, P. Brandt +17
The site survey for the Advanced Technology Solar Telescope concluded recently after more than two years of data gathering and analysis. Six locations, including lake, island and c…
Are Electric Currents Heating the Magnetic Chromosphere?
H. Socas-Navarro
This paper presents an analysis of three-dimensional vector currents and temperatures observed in a sunspot from the photosphere to the chromosphere, spanning a range of heights of…
The Three-Dimensional Structure of a Sunspot Magnetic Field
H. Socas-Navarro
Here we report on observations of the three-dimensional structure of a sunspot magnetic field from the photosphere to the chromosphere, obtained with the new visible/infrared spect…
SPINOR: Visible and Infrared Spectro-Polarimetry at the National Solar Observatory
H. Socas-Navarro, D. Elmore, A. Pietarila +3
SPINOR is a new spectro-polarimeter that will serve as a facility instrument for the Dunn Solar Telescope at the National Solar Observatory. This instrument is capable of achromati…
Spectro-polarimetric observations and non-LTE Modeling of Ellerman bombs
H. Socas-Navarro, V. Martinez Pillet, D. Elmore +3
Ellerman bombs are bright emission features observed in the wings of H, usually in the vicinity of magnetic concentrations. Here we show that they can also be detected in the Ca…
Polynomial Approximants for the Calculation of Polarization Profiles in the \ion{He}{1} 10830 ÅMultiplet
H. Socas-Navarro, J. Trujillo Bueno, E. Landi Degl'Innocenti
The \ion{He}{1} multiplet at 10830 Åis formed in the incomplete Paschen-Back regime for typical conditions found in solar and stellar atmospheres. The positions and strengths of th…
