Investigation of the Production and Evolution of Chromospheric, EUV, and X-Ray Jets using Observations from Hinode, STEREO, and SDO
ROSES ID: NNH10ZDA001N Selection Year: 2011
Program Element: Focused Science Topic

Summary:
We propose a four-year program in response to the Living With a Star (LWS)
Targeted Research and Technology (TR&T) solicitation, a Targeted Investigation
under Focused Science Topic 1.2.1.(c): ``Jets in the Solar Atmosphere and
their Effects in the Heliosphere.'' We will study solar jets, using data
primarily from the Hinode, SDO, and STEREO satellites. The solar jets include
chromospheric spicules, especially type II spicules; EUV (transition region)
jets; and X-ray (coronal) jets. We will use data from all three Hinode
instruments: SOT, EIS, and XRT; from AIA and HMI on SDO, from SECCHI on STEREO;
and we will also use data from other sources, such as SOHO/LASCO. Our study
will focus on four main study topics: (1) the origin and evolution of spicules
on and just inside the limb, using SOT/Ca ii data and image processing
techniques; (2) the location of polar spicules (and other jets when possible)
relative to the magnetic network, using mainly SOT/Ca ii data with SOT
spectropolarimeter (SP) and HMI vector magnetograms; (3) the connection between
jets and features at chromospheric, EUV, and soft X-ray (SXR) wavelengths; and
(4) the detailed nature of the X-ray jet mechanism and the implications for the
same mechanism occurring on the size scale of chromospheric spicules, and also
the connection between X-ray jets (and other jets) and coronal outflows into
the heliosphere visible in coronagraph images. Most of our projects can be
completed with already-identified or readily-available data sets. New
observations from Hinode may be requested but are not required for the success
of the project. Both the P.I. and Co-I have extensive experience with the type
of data sets to be used, and a worker at the postdoc level will be supported.
This work will address the Targeted Investigation objectives by increasing our
understanding of jet origins, development, manifestations in different
wavelength regimes, and connections to the coronal outflows at the base of the
heliosphere. This work is relevant to NASA in that it will result in
scientific output from several NASA-related satellites, and in that--in
studying solar jets--this work will yield new insights into a likely major
source of the solar wind, which is an important component of ``space weather.''
