Journal ArticleDOI

The formation of a sunspot penumbra

TL;DR: In this article, the formation of a penumbra in the leading spot was observed at a cadence of 5 images per second for the next 4:40 h, interrupted by one large gap of 35 min and a few more small gaps of about 10 min.
Journal ArticleDOI

Detection of vortex tubes in solar granulation from observations with sunrise

TL;DR: In this paper, the authors investigated a time series of continuum intensity maps and corresponding Dopplergrams of granulation in a very quiet solar region at the disk center, recorded with the Imaging Magnetograph eXperiment (IMaX) on board the balloon-borne solar observatory SUNRISE.
Journal ArticleDOI

The horizontal internetwork magnetic field : numerical simulations in comparison to observations with hinode

TL;DR: In this article, the authors investigate realistic numerical simulations of the surface layers of the Sun with respect to horizontal magnetic fields and compute the corresponding polarimetric response in the Fe i 630 nm line pair.
Journal ArticleDOI

Relation between photospheric magnetic field and chromospheric emission

TL;DR: In this paper, the authors investigated the relationship between the photospheric magnetic field and the emission of the mid chromosphere of the Sun and found that a dominant fraction of the calcium emission caused by the heated atmosphere in the magnetic network has non-magnetic origin.
Journal ArticleDOI

The signature of chromospheric heating in Ca II H spectra

TL;DR: In this paper, the authors analyzed a 1-h time series of cospatial Call H intensity spectra and photospheric polarimetric spectra around 630 nm to derive the signature of the chromospheric heating process in the spectra.
