Abstract
We present a study of a recurring jet observed on October 31, 2011 by
SDO/AIA, Hinode/XRT and Hinode/EIS. We discuss the physical parameters of the
jet such as density, differential emission measure, peak temperature, velocity
and filling factor obtained using imaging and spectroscopic observations. A
differential emission measure (DEM) analysis was performed at the region of the
jet-spire and the footpoint using EIS observations and also by combining AIA
and XRT observations. The DEM curves were used to create synthetic spectra with
the CHIANTI atomic database. The plasma along the line-of-sight in the
jet-spire and jet-footpoint was found to be peak at 2.0 MK. We calculated
electron densities using the Fe XII ($\lambda
