中文摘要
大多数太阳耀斑被归类为脉冲,具有硬X射线光谱,随着通量增加而变得相对更有活力(或“硬化”),随着通量下降而“软化”。 相反,与高能行星际质子相关的硬X射线光谱随着通量的下降而逐渐“硬化”。 虽然与日冕物质抛射相关的冲击波可能会产生大部分行星际质子,但逐渐硬化的耀斑也会产生中等数量的高能质子;事实上,逐渐硬化的耀斑和日冕物质抛射经常同时发生。 因此,研究人员将专注于这种逐渐硬化的耀斑,以优化硬X射线和微波的质子预测算法。 此外,他还寻求合作,用一个特别好的观测事件对粒子加速场进行建模,并用一个新的硬X射线光谱仪对硬化耀斑进行新的观测。
英文摘要
Most solar flares are classified as impulsive, having hard X-ray spectra that become relatively more energetic (or 'harden') as fluxes increase, and 'soften' as fluxes decline. Conversely, hard X-ray spectra associated with energetic interplanetary protons progressively 'harden' as fluxes decline. Although coronal mass ejection-associated shocks may produce the majority of interplanetary protons, moderate numbers of high energy protons are also produced by progressively hardening flares; in fact, progressively hardening flares and coronal mass ejections often occur simultaneously. Thus, the investigator will focus on this progressively hardening flare to optimize proton prediction algorithms for both hard X-rays and microwaves. In addition, he pursues a collaboration for modeling the particle acceleration site with a particularly well-observed event, and new observations of hardening flares with a new hard X-ray spectrometer.
