The catalog of Hvar Observatory solar observations

Mateja Dumbovic, Luci Karbonini, Jasa Calogovic +5

We compile the catalog of Hvar Observatory solar observations in the time period corresponding to regular digitally stored chromospheric and photospheric observations 2010-2019. We…

Comparison of the sidereal angular velocity of subphotospheric layers and small bright coronal structures during the declining phase of solar cycle 23

Amel Zaatri, Hubertus Woehl, Markus Roth +2

Context. We compare solar differential rotation of subphotospheric layers derived from local helioseismology analysis of GONG++ dopplergrams and the one derived from tracing small…

Solar Simulations for the Atacama Large Millimeter Observatory Network

Sven Wedemeyer, Tim Bastian, Roman Brajsa +2

The Atacama Large Millimeter/submillimeter Array (ALMA) will be a valuable tool for observing the chromosphere of our Sun at (sub-)millimeter wavelengths at high spatial, temporal…

Are there Radio-quiet Solar Flares?

Arnold O. Benz, Roman Brajsa, Jasmina Magdalenic

Some 15% of solar flares having a soft X-ray flux above GOES class C5 are reported to lack coherent radio emission in the 100 - 4000 MHz range (type I - V and decimetric emissions)…

Solar ALMA Observations - A new view of our host star

Sven Wedemeyer, Tim Bastian, Roman Brajsa +5

ALMA provides the necessary spatial, temporal and spectral resolution to explore central questions in contemporary solar physics with potentially far-reaching implications for stel…

Atacama Large Aperture Submillimeter Telescope (AtLAST) Science: Solar and stellar observations

Sven Wedemeyer, Miroslav Barta, Roman Brajsa +35

Observations at (sub-)millimeter wavelengths offer a complementary perspective on our Sun and other stars, offering significant insights into both the thermal and magnetic composit…

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…
