Microwave diagnostics of magnetic field strengths in solar flaring loops

Tian, Hui; Zhu, Rui; Xu, Yu +5 more

We have performed microwave diagnostics of the magnetic field strengths in solar flare loops based on the theory of gyrosynchrotron emission. From Nobeyama Radioheliograph observations of three flare events at 17 and 34 GHz, we obtained the degree of circular polarization and the spectral index of microwave flux density, which were then used to ma…

Solar ultraviolet bursts in a coordinated observation of IRIS, Hinode and SDO

Tian, Hui; Samanta, Tanmoy; He, JianSen +3 more

Solar ultraviolet (UV) bursts are small-scale compact brightenings in transition region images. The spectral profiles of transition region lines in these bursts are significantly enhanced and broadened, often with chromospheric absorption lines such as Ni~{\sc{ii}} 1335.203 and 1393.330 Å superimposed. We investigate the properties of several UV b…

MHD and kinetic analysis of flow bursts in the Earth's plasma sheet

Dandouras, I.; Reme, H.; Cao, JinBin +6 more

In an attempt to study the flow bursts in the Earth's plasma sheet we select an event that took place on August 7, 2004 in the expansion phase of a substorm, using data from the geomagnetic index, solar wind data, plasma and magnetic field observations from C1 Cluster satellite (the Cluster mission has 4 satellites) and from Double Star TC-1 satel…
