Understanding the Relationship between Solar Coronal Abundances and F10.7 cm Radio Emission
Andy S. H. To, Alexander W. James, T. S. Bastian +7
Sun-as-a-star coronal plasma composition, derived from full-Sun spectra, and the F10.7 radio flux (2.8 GHz) have been shown to be highly correlated (r = 0.88) during solar cycle 24…
The quiet Sun at mm Wavelengths as Seen by ALMA
Costas Alissandrakis, Timothy Bastian, Roman Brajša
Solar observations at sub-mm, mm and cm wavelengths offer a straightforward diagnostic of physical conditions in the solar atmosphere because they yield measurement of brightness t…
A first look at the submillimeter Sun with ALMA
C. E. Alissandrakis, T. S. Bastian, A. Nindos
We present the first full-disk solar images obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) in Band 7 (0.86 mm; 347 GHz). In spite of the low spatial resoluti…
ALMA observations of the variability of the quiet Sun at millimeter wavelengths
A. Nindos, S. Patsourakos, C. E. Alissandrakis +1
Using Atacama Large Millimeter/submillimeter Array (ALMA) observations of the quiet Sun at 1.26 and 3 mm, we study spatially resolved oscillations and transient brightenings, i.e.…
Radio Spectral Imaging of an M8.4 Eruptive Solar Flare: Possible Evidence of a Termination Shock
Yingjie Luo, Bin Chen, Sijie Yu +2
Solar flare termination shocks have been suggested as one of the viable mechanisms for accelerating electrons and ions to high energies. Observational evidence of such shocks, howe…
ALMA and IRIS Observations of the Solar Chromosphere II: Structure and Dynamics of Chromospheric Plage
Georgios Chintzoglou, Bart De Pontieu, Juan Martínez-Sykora +7
We propose and employ a novel empirical method for determining chromospheric plage regions, which seems to better isolate plage from its surrounding regions compared to other metho…
