Quasi-periodic Pulsations in a Solar Microflare
Irregular time evolution of the radio emission generated in a B2-class microflare (SOL2017-01-25T10:15), occurring on 2017 January 25 in active region 12,628, is studied. The microflare was
Origin of the Modulation of the Radio Emission from the Solar Corona by a Fast Magnetoacoustic Wave
Observational detection of quasi-periodic drifting fine structures in a type III radio burst associated with a solar flare SOL2015-04-16T11:22, with the LOw Frequency ARray (LOFAR), is presented.
Multi-wavelength spatially resolved analysis of quasi-periodic pulsations in a solar flare
Aims. We aim to perform a spatially resolved analysis of a quasi-periodic pulsation event from 8th May 1998 using microwave data from the Nobeyama Radioheliograph and Radiopolarimeter, and X-ray data
Relationship of Type III Radio Bursts with Quasi-periodic Pulsations in a Solar Flare
We studied a solar flare with pronounced quasi-periodic pulsations detected in the microwave, X-ray, and radio bands. We used correlation, Fourier, and wavelet analyses methods to examine the
Types of Microwave Quasi-Periodic Pulsations in Single Flaring Loops
Quasi-periodic pulsations (QPP) of microwave emission generated in single flaring loops observed with the Nobeyama Radioheliograph (NoRH) and Nobeyama Radio Polarimeters (NoRP) are studied. Specific
Multi-mode quasi-periodic pulsations in a solar flare
Context. Quasi-periodic pulsations (QPP) of the electromagnetic radiation emitted in solar and stellar flares are often detected in microwave, white light, X-ray, and gamma-ray bands. Mechanisms
Observation of quasi-periodic solar radio bursts associated with propagating fast-mode waves
Radio emission observations from the Learmonth and Bruny Island radio spectrographs are analysed to determine the nature of a train of discrete, periodic radio \lq sparks\rq (finite-bandwidth,
Soft X-Ray Pulsations in Solar Flares
The soft X-ray emissions (hν>1.5 keV) of solar flares mainly come from the bright coronal loops at the highest temperatures normally achieved in the flare process. Their ubiquity has led to their use
Siberian Radioheliograph: First Results
Regular observations of active processes in the solar atmosphere have been started using the first stage of the multiwave Siberian Radioheliograph (SRH), a T-shaped 48-antenna array with a 4-8 GHz
Quasi-periodic pulsations in the most powerful solar flare of Cycle 24
Quasi-periodic pulsations (QPP) are common in solar flares and are now regularly observed in stellar flares. We present the detection of two different types of QPP signals in the thermal emission
