Uncovering the heterogeneity of a solar flare mechanism with mixture models

Frontiers in Astronomy and Space Sciences
The physics of solar flares occurring on the Sun is highly complex and far from fully understood. However, observations show that solar eruptions are associated with the intense kilogauss fields of active regions, where free energies are stored with ...

SUNSPOT dan FLARE Adakah hubungannya?

, 1980
RINGKASAN:Ukuran aktif tidaknya Matahari paling mudah diamati dengan menentukan bilangan sunspot. Ada ukuran lainnya yaitu frekwensi terjadinya flare.. Karena flare menimbulkan gangguan pada ionosfir yang menjadi lapisan pemantul gelom-bang radio, lebih ...

Kaitan Flare Dengan Pemunculan Sunspot

, 2001
Peristiwa flare umumnya akan terjadi di llingkungan suspot/grup sunspot. Sumber energi pembentuk flare adalah medan magnet sunspot. Makin banyak/besar sunspot/grup sunspot makin banyak juaga peristiwa flare yang terjadi.

Solar Flare Ion Temperatures

The Astrophysical Journal Letters
Abstract This Letter proposes that the ion temperature is several times the local electron temperature in the hot onset phase and in the above-the-loop region of solar flares. The Letter considers: the evidence of spectral line Doppler widths (“nonthermal” broadening); evidence for “universal” ion and electron temperature increase ...

Revisiting Approaches to Stellar White-light Flare Energy Based on Spatiotemporally Resolved Solar Observations

The Astrophysical Journal Letters
Accurately estimating the bolometric energy of solar and stellar white-light flares (WLFs) is crucial for understanding their physical nature and impact on surrounding planets.

The Solar Flare 4: 10 keV X-ray Spectrum

, 2004
The 4-10 keV solar flare spectrum includes highly excited lines of stripped Ca, Fe, and Ni ions as well as a continuum steeply falling with energy. Groups of lines at approximately 7 keV and approximately 8 keV, observed during flares by the broad-band ...
