[PEM14-P09] Recent and Upcoming Studies of Solar Coronal Jets
キーワード：Sun, Solar Coronal Jets, Solar Coronal Activity
Solar jets occur throughout the solar atmosphere, including in coronal holes, quiet regions,
and active regions. Observations at X-ray and EUV wavelengths show that frequently
jets are made by eruptions of small-scale filaments, called “minifilaments.” Recent studies
indicate that many of, or even the majority of, these jet-producing minifilament eruptions
occur at locations where opposite-polarity photosphere magnetic fluxes merge and cancel.
These observations support the idea that flux cancelation builds a magnetic flux rope along
which cool minifilament material gathers, and that the flux rope subsequently erupts to form
the jet through a sequence of magnetic reconnections. In this presentation we will update
our recent investigations into jets, and discuss expectations and needs for jet studies with
new Sun-observing instruments.
