DOI: 10.1007/s11207-017-1069-4

Abstract: Small-scale solar magnetic fields demonstrate features of fractal intermittent behavior, which requires quantification. For this purpose we investigate how the observational estimate of the solar magnetic flux density B$B$ depends on resolution D$D$ in order… read more here.

Published in 2017 at "Astronomy and Astrophysics"

DOI: 10.1051/0004-6361/201629156

Abstract: We have used our robotic TIGRE facility to closely monitor the star τ Boo during the last three observing seasons 2013–2016 and to determine its S -index variability from the strength of its Ca ii… read more here.
