- Local Nuclear Mass Relations
- Abstract
- The masses are the basic properties of atomic nuclei.
In this talk, we will discuss the Garvey-Kelson mass relations as one of the best example schemes of local nuclear mass relations and, report in particular our recent results of researches which we have carried out in the Shanghai Jiao Tong University.
The essential point is how to use and improve the Garvey-Kelson relations.
We plan to apply our result to explosive nucleosynthesis in SNe. - Facilitator

- Title
- Dynamical Phenomena in Light Bridges
- Abstract
- Light bridges are elongated bright structures often visible in a sunspot umbra that present a variety of dynamic phenomena from the photosphere to the corona. It is widely believed that such phenomena originate from the complex topology of magnetic fields and magnetoconvection in the light bridges, but the nature and origin are still poorly understood. In this talk, I will explain the physical nature and origin of (1) arcsecond-scale chromospheric plasma ejections above a light bridge, (2) transiently enhanced brightenings detected along a light bridge, and (3) oscillations and waves in light bridges. Our analysis were carried out by using the high resolution spectral data taken by the Fast Imaging Solar Spectrograph (FISS) and the interface Region Imaging Spectrograph (IRIS). The important finding of our study is that upward-propagating shock waves excited in the low chromosphere of the light bridges appear as fine-scale structures such as plasma ejections and enhanced brightenings above the light bridges. I will also explain about the oscillations and waves in light bridges.
