  3. Space Research Institute Almost 40 years of theoretical and experimental space exploration About 80 scientists and engineers from 11 nations in 3 departments Working topics: • Instrumental development • Gravitational Field of Earth • Space Plasma Physics • Solar System Exploration IWF/ÖAW GRAZ

  4. Magnetometer Front-end ASIC Complete active readout electronics for a fluxgate sensor on 20 mm2 of silicon with 350nm structures • Miniaturization (/4-5) • TID radiation hardness (x4) • Power reduction (/10) • Offset stability (/2) IWF/ÖAW GRAZ

  5. E-BOX MAG-OS Ausleger/Boom (90 cm) Venus Express • Magnetometer group had the lead position • Extremely efficient international cooperation with TU Braunschweig and Imperial College London • Short development time(< 2 years) • Challenging thermal conditions around Venus(2 to 3 suns) • Design, manufacturing and qualification of theboom by the VEXMAG Team • Impressive science output MAG-IS IWF/ÖAW GRAZ

  6. Solar-Planetary Relations Reconnection at the Sun • Determination of magnetic flux change rates and of amount of magnetic reconnection flux in solar flares from observations to test standard flare models • Comparison of total flare reconnection flux with magnetic flux in MCs to understand the relation between the solar source and the associated MC Numerical Simulation of Magnetic Clouds (MCs) • Code-Development for a numerical solution of the hyperbolic system of ideal MHD governing equations • Investigate propagation of MCs from the sun to Earth – interaction between MC and structured solar wind • Compare simulated parameters with observations; support for interpreting observations Modeling of MCs from in-situ data Reconstruction of magnetic clouds from multi-spacecraft observations (e.g. STEREO) with a new method: non force-free, not prescribing the geometry Yields more accurate shapes, magnetic fluxes and axis orientations These act as constraints on models of coronal mass ejection initiation and their propagation in the solar wind

  7. Vex BepiColombo MMS THEMIS DSP Cluster RBSP Participating missions:Cluster:CoI (EDI,CIS,FGM, PEACE);DSP:PI (FGM), CoI (FGM,HIA)THEMIS:CoI (FGM);Vex:PI/CoI(MAG);MMS: Collab./CoI (Fields)RBSP: CoI(EMFISIS);BepiColombo:PI/CoI (MerMag) Magnetospheric Physics IWF/ÖAW GRAZ

  8. Radio Emissions • Antenna calibration • Cassini, Mars Express, Interball-2, STEREO, Resonance, • In preparation: JUNO, Solar Orbiter • Applied Methods: Rheometry, numerical simulation, in-flight calibration • Newly Developed Techniques and Software • Mutual Impedance Rheometry(Influence of mutual capacitances in triaxial antenna systems) • High-frequency transfer matrix representation of antennas, implemented in MATLAB antenna toolbox, 1. application to SED • Formula for the correction of antenna radii • Implementation of CONCEPT in antenna toolbox (wire & patch modelling) IWF/ÖAW GRAZ

  9. Radio Emissions • Radio Emissions & Atmospheric Electricity • Saturn Kilometric Radiation (SKR) • Auroral Kilometric Radiation (AKR) • Lightning search and simulation (Titan, Saturn-SEDs) • Propagation of EM waves through plasma • Jupiter radio emissions, ground based observations • Solar radio emissions • Instruments • Exoplanets IWF/ÖAW GRAZ
