Inverse Total Variation Flow

Abstract. In this paper we analyze iterative regularization with the Bregman distance of the total variation semi norm. Moreover, we prove existence of a solution of the corresponding flow equation as introduced in [8] in a functional analytical setting using methods from convex analysis. The results are generalized to variational denoising methods with L-norm fit-to-data terms and Bregman dist...

Observational manifestations of solar magneto-convection — center-to-limb variation

We present the first center-to-limb G-band images synthesized from high resolution simulations of solar magneto-convection. Towards the limb the simulations show “hilly” granulation with dark bands on the far side, bright granulation walls and striated faculae, similar to observations. At disk center G-band bright points are flanked by dark lanes. The increased brightness in magnetic elements i...

Center-to-Limb Variation of Solar 3-D Hydrodynamical Simulations

We examine closely the solar Center-to-Limb variation of continua and lines and compare observations with predictions from both a 3-D hydrodynamic simulation of the solar surface (provided by M. Asplund and collaborators) and 1-D model atmospheres. Intensities from the 3-D time series are derived by means of the new synthesis code Assǫt, which overcomes limitations of previously available codes...

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...

Temporal evolution of the Evershed flow in sunspots I. Observational characterization of Evershed clouds

Context. The magnetic and kinematic properties of the photospheric Evershed flow are relatively well known, but we are still far from a complete understanding of its nature. The evolution of the flow with time, which is mainly due to appearance of velocity packets called Evershed clouds (ECs), may provide information to further constrain its origin. Aims. We undertake a detailed analysis of the...
