AGU Fall Meeting Session: "Effects of Suprathermal Electrons in Space Plasmas" ---------------------------------------------------------------------- From: George Khazanov Dear Colleagues: Please consider submitting an abstract to Session 2166, "Effects of Suprathermal Electrons in Space Plasmas," at the AGU Fall Meeting, 15- 19 December, 2014 in San Francisco, CA. Session ID#: 2166 Session Description: Superthermal Electrons (SE), with energies a factor of 5-10 greater than the plasma thermal energy, play a crucial role in the heating and acceleration of plasma in several important space and astrophysical contexts. They interact with the thermal population thorough Coulomb collisions, affect the generation of the ambipolar electric field, and contribute to the collisionless electron heat flux processes. For the Earth's environment, it has been demonstrated that SEs play a controlling role in the plasmasphere thermal structure, have a major effect on ionospheric outflows, and through the generation of heat flux control the electron temperature and consequently the topside ionospheric scale height. In the solar corona, such electrons make the dominant contribution to the electron heat flux and, thus, play an important role in the coronal heating energy budget. SE also support large ambipolar electric fields along open magnetic flux tubes in stellar coronae and in planetary ionospheres and thus contribute significantly to solar and stellar wind acceleration, outflow from planetary ionospheres and possibly even exoplanetary atmospheric loss. In this session, we solicit presentations on the role of SE transport in the following contexts: 1) The role of SE in plasmaspheric refilling and polar wind formation and affiliated Magnetosphere- Ionosphere coupling phenomena, 2) solar and stellar wind acceleration, 3) the coronal heating problem (specifically, the role of non-Spitzer- Harm heat flux and superthermal tails in the coronal energy budget), 4) Remote observations of SE in the solar corona, 5) In situ observations of SE in Earth's ionosphere and magnetosphere and other planetary atmospheres, 6) new computational techniques for the kinetic modeling of SE in solar/stellar coronae, in Earth's ionosphere and magnetosphere, and other planetary systems.

This session is directly related to the new GEM Focus Group (FG), Inner Magnetosphere Cross-Energy/Population Interactions (IMCEPI), and we are especially interested in contributed presentations related to this FG. Session Description: The Earth’s inner magnetosphere (L <= ~ 8), strongly coupled with the ionosphere, consists of the ring current, plasma sheet, plasmasphere, radiation belts, etc.. Particles at thermal, energetic, and relativistic energy levels populate this region of geospace and can interact with each other. The types of cross-energy interactions include 1) DC electric field perturbations, 2) large-scale magnetic field distortions, 3) control and modulation of plasma wave excitation, propagation, and absorption, and 4) precipitation resulting in ionization, excitation, and heating of the upper atmosphere. Observations of plasma, fields, and waves from several space missions (e.g., the Van Allen Probes, Cluster, THEMIS, TWINS, and GOES) and progress in modeling and theory are improving our understanding of the inner magnetosphere cross-energy interactions. We invite presentations about observations, numerical simulations, theoretical investigations, or their combination that address particle and wave dynamics in the inner magnetosphere and, in particular, the interactions across plasma population boundaries.

JOB OPENING: Faculty Search in Space Physics at UCLA ---------------------------------------------------------------------- From: Larry Lyons The UCLA Department of Atmospheric and Oceanic Sciences (AOS) seeks outstanding applicants for a ladder faculty position in Space Physics. Preference is for an appointment at the Assistant or Associate level, but more senior levels will also be considered. Candidates with research interests in any aspect(s) of Magnetospheric or Ionospheric Physics, including coupling with the Thermosphere, are encouraged to apply. Backgrounds in theory, modeling, and/or observational analysis will be considered. The UCLA Space Physics program is cooperative and interdepartmental, including faculty in the Earth, Planetary, and Space Sciences and the Physics Departments. The UCLA Department of Atmospheric and Oceanic Sciences, is a vibrant and collaborative department with faculty interested in atmospheric, climate, and ocean dynamics, as well as Space Physics. The ability of applicants to profit from, complement, and further contribute to UCLA’s long-standing strength in Space Physics will be a consideration in evaluation. The successful applicant must hold a Ph.D. (or equivalent) degree at the time of appointment and will be expected to contribute to the teaching mission of the AOS department, at both the graduate and undergraduate levels. He or she will also be expected to lead or develop a first rate research program in Space Physics, including interactions with others of all levels within the UCLA Space Physics community. Salary will be commensurate with education and experience. The target start date is on or after July 1, 2015. Please submit your online application to the Search Committee for faculty position in Space Physics (https://recruit.apo.ucla.edu/apply/JPF00266) (tracking #0965- 1415- 01). Please include: (i) a detailed statement of teaching and research interests; (ii) curriculum vitae; (iii) a list of 3-4 individuals who are familiar with your work and can serve as a reference. Applications are due by October 15, 2014, but the position will remain open until filled. The University of California is an Equal Opportunity/Affirmative Action Employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, national origin, disability, age or protected veteran status.
