Comparison of solar multifrequency microwave data with other solar indices for understanding solar and stellar microwave data

Masumi Shimojo, Kosuke Namekata, Kazumasa Iwai +2

Thermal microwave emissions detected from stellar atmospheres contain information on stellar activity. However, even for the Sun, the relationship between multifrequency microwave…

Solar Observing with the Atacama Large Millimeter-Submillimeter Array

Timothy Bastian, Masumi Shimojo, Miroslav Barta +2

The Atacama Large Millimeter-submillimeter Array (ALMA), sited on the high desert plains of Chajnantor in Chile, has opened a new window onto solar physics in 2016 by providing con…

The Brightness Temperature of the Quiet Solar Chromosphere at 2.6 mm

Kazumasa Iwai, Masumi Shimojo, Shinichiro Asayama +4

The absolute brightness temperature of the Sun at millimeter wavelengths is an important diagnostic of the solar chromosphere. Because the Sun is so bright, measurement of this pro…

Spectral Structures and Their Generation Mechanisms for Solar Radio Type-I Bursts

Kazumasa Iwai, Yoshizumi Miyoshi, Satoshi Masuda +3

The fine spectral structures of solar radio type-I bursts were observed by the solar radio telescope AMATERAS. The spectral characteristics, such as the peak flux, duration, and ba…
