Title
Toward an understanding of particle acceleration in a solar flare
Abstract
A solar flare is one of powerful particle accelerators in our space, in which electrons and ions are accelerated more than MeV and GeV, respectively. Understanding the mechanism of particle acceleration is a long standing issue not only in solar physics but also plasma physics, space physics, and astrophysics. Many flare observations have been devoted to reveal the nature of accelerated particles via X-ray, gamma-ray, and microwave, and have established that magnetic reconnection plays a fundamental role on the flare and following phenomena. Also, many theoretical studies have been conducted to understand the particle acceleration mechanism in magnetic reconnection and its associated phenomena (e.g., shock, turbulence, etc.). In this talk, I review recent achievements on the flare particle acceleration, and then discuss perspective for future mission PhoENiX.

タイトル
The magnetic field strength and energetics of OMC 1
Abstract
We are entering a new era of astronomical polarimetry, in which new and stringent observational contraints are being placed on the role of magnetic fields in star formation. In this talk, I will present James Clerk Maxwell Telescope (JCMT) POL-2 polarimetric observations of the OMC 1 region of the Orion A filament, taken as part of the BISTRO (B-Fields in Star-Forming Region Observations) survey. I will discuss modifications to the Chandrasekhar-Fermi method which allow estimation of plane-of-sky magnetic field strengths in the presence of a magnetic field showing large-scale, ordered variation, and will derive an estimate of the magnetic field strength in OMC 1. I will discuss the energetic importance and evolutionary history of the magnetic field in the OMC 1 region, with particular emphasis on the interaction between the magnetic field and the explosive BN/KL outflow.
