چکیده

The uncombed penumbral model explains the structure of the sunspot penumbra in terms of thick magnetic fibrils embedded in a magnetic surrounding atmosphere. This model has been successfully applied to explain the polarization signals emerging from the sunspot penumbra. Thick penumbral fibrils face some physical problems, however. In this contribution we will offer possible solutions to these shortcomings.

Field - Free Gaps near Τ = 1 in Sunspot Penumbrae ?

The vertical stratification of the magnetic field strength in sunspot penumbrae is investigated by means of spectropolarimetric observations at high spatial resolution from the Hinode spacecraft. Assuming that the magnetic field changes linearly with optical depth we find that, in those regions where the magnetic field is more inclined and the Evershed flow is strongest (penumbral intraspines),...

Spectral signature of uncombed penumbral magnetic fields

The uncombed penumbral model proposed by Solanki & Montavon (1993) is used to understand some recent observational results found in penumbrae. This model uses a penumbral magnetic field structured into horizontal flux tubes embedded in a more vertical background field. A modified version of this model, with a weaker field strength in the horizontal tubes, is used to explain the gradient with he...

Temporal evolution of the Evershed flow in sunspots II. Physical properties and nature of Evershed clouds

Context. Evershed clouds (ECs) represent the most conspicuous variation of the Evershed flow in sunspot penumbrae. Aims. We determine the physical properties of ECs from high spatial and temporal resolution spectropolarimetric measurements. Methods. The Stokes profiles of four visible and three infrared spectral lines are subject to inversions based on simple one-component models as well as mor...

Heat transfer in sunspot penumbrae Origin of dark-cored penumbral filaments

Context. Observations at 0. 1 have revealed the existence of dark cores in the bright filaments of sunspot penumbrae. Expectations are high that such dark-cored filaments are the basic building blocks of the penumbra, but their nature remains unknown. Aims. We investigate the origin of dark cores in penumbral filaments and the surplus brightness of the penumbra using an uncombed penumbral model...

The structure of a penumbral connection between solar pores

High resolution 2D-spectro-polarimetric observations have been used to analyse the magnetic field and flow topologies of a penumbral connection between two opposite polarity solar pores. A filamentary structured Evershed-like material flow from one pore to the other along the magnetic field lines has been detected. The flow channels are co-spatial with bright penumbral filaments close to the po...
