Inferring the magnetic field vector in the quiet Sun. III. Disk variation of the Stokes profiles and isotropism of the magnetic field
J. M. Borrero, P. Kobel
We have studied the angular distribution of the magnetic field vector in the solar internetwork employing high-quality data (noise level in units of the…
On the surface structure of sunspots
Morten Franz
A precise knowledge of the surface structure of sunspots is essential to construct adequate input models for helioseismic inversion tools. We summarize our recent findings about th…
The quasi-biennial periodicity as a window on the solar magnetic dynamo configuration
R. Simoniello, K. Jain, S. C. Tripathy +5
Manifestations of the solar magnetic activity through periodicities of about 11 and 2 years are now clearly seen in all solar activity indices.In this paper, we add information abo…
Seismic comparison of the 11 and 2 yr cycle signatures in the Sun
R. Simoniello, K. Jain, S. C. Tripathy +3
The solar magnetic activity consists of two periodic components: the main cycle with a period of 11 yr and a shorter cycle with a period of ~2 yrs. The origin of this second period…
A retrospective of the GREGOR solar telescope in scientific literature
C. Denker, O. von der Lühe, A. Feller +33
In this review, we look back upon the literature, which had the GREGOR solar telescope project as its subject including science cases, telescope subsystems, and post-focus instrume…
The GREGOR Fabry-Pérot Interferometer
K. G. Puschmann, C. Denker, F. Kneer +18
The GREGOR Fabry-Pérot Interferometer (GFPI) is one of three first-light instruments of the German 1.5-meter GREGOR solar telescope at the Observatorio del Teide, Tenerife, Spain.…
