Modeling brightness temperature of sunspots using ALMA single-dish observations
F. MatkoviÄ, R. BrajÅ¡a, A. O. Benz +5
We model sunspot brightness temperature in the wavelength range 0.3-10mm using the Atacama Large Millimeter/submillimeter Array (ALMA) single-dish measurements together with other…
An analysis of the solar differential rotation in solar cycle No. 19 (1954-1964) determined using Kanzelhoehe sunspot group positions
Ivana Poljancic Beljan, Luka Sibenik, Tomislav Jurkic +7
We study solar differential rotation (DR) for solar cycle No. 19 (1954-1964) by tracing sunspot groups on the sunspot drawings of Kanzelhoehe Observatory for Solar and Environmenta…
Modeling brightness temperature of prominences on the solar disk using ALMA single-dish observations
F. MatkoviÄ, R. BrajÅ¡a, A. O. Benz +5
Prominences (PRs) are among the most common solar phenomena, yet their full physical picture, particularly their chromospheric mm emission, remains incomplete. The new Atacama Larg…
Coronal bright point statistics II. Magnetic polarities and mini loops
I. Kraus, Ph. -A. Bourdin, J. Zender +2
Context. The solar corona maintains temperatures of a million Kelvin or more. The plasma heating mechanisms responsible for these extreme temperatures are still unclear. Large regi…
