Presentation Transcript

  1. Heliospheric Working Group • Eberhard Möbius (for Gary Zank), Justin Kasper • Chuck Smith (invitation & charge)John Richardson, Eric Christian, Nancy Crooker, Marcia Neugebauer, Hans Müller, Joe Giacalone, John Bieber • Emissaries: in: Bob Lin, B. C. Low out: John Bieber, Nancy Crooker IHY Workshop April 2004Eberhard Möbius, UNH SSC

  2. Goals • Carry out the Message (and Connect)Heliospheric Science contributes to wider community (Astronomy {Origins} & Solar System exploration)Heliospheric Science is about Exploration (general public) • Understand Our Home System from the Sun to its Boundary with the Interstellar Medium • Maintain Existing Assets in SpaceOur Great Observatory: Heliospheric Fleet • Improve & Consolidate Global Heliospheric Models Current: plasma+neutrals; plasma+magnetic field • Need: all combined IHY Workshop April 2004Eberhard Möbius, UNH SSC

  3. Campaigns • 3D-Heliosphere at the A- Solar Minimum (1 AU - VLISM) (3Do) (E.M., C.S., & …) Existing Assets: ACE, Voyager (distance and latitude), Ulysses (fast lat. scan+polar passes), SOHO, Wind, Cassini, MGS, IMAGE, …Archived Data: Pioneers, Galileo, …New: STEREO, …Ground Observatories: Neutron Monitors, • Modeling: Multi-fluid & Kinetic models, … IHY Workshop April 2004Eberhard Möbius, UNH SSC

  4. Campaigns • 3D-Heliosphere at the A- Solar Minimum (Sun - 2 AU) (3Di) (J.K. & … Existing Assets: ACE, Ulysses (fast lat. scan+polar passes), SOHO, Wind, RHESSI, SMEI, MGS Archived Data: Helios, IMP-8, ISEE-3, PVO, …New: Solar-B; STEREO; MESSENGERGround Observatories: Low Freq. Radio Observatories, IPS, Optical Solar Observatories, µ-DetectorsModeling: 3D-MHD, Potential Field, Kinetic, … IHY Workshop April 2004Eberhard Möbius, UNH SSC

  5. Campaigns • Comparative interplanetary shock study (CS) (planetary, comet, interplanetary, Termination, …)Assets: ACE, Cluster, RHESSI, SOHO, Ulysses, Voyager, Wind, Archival, Modeling • - Intercalibration of SW observations (SWI) (J.R.) (consolidate distribution functions & make the data available! Assets: Wind, ACE, SOHO, Ulysses, Voyager, … • - Study of the Heliosphere near the Termination Shock (TS)Assets: Voyager, theory, modeling IHY Workshop April 2004Eberhard Möbius, UNH SSC

  6. Questions • - Provide a consistent view of the 3D heliosphere (modeling from corona to ISM) (3Di, o) • What is the SW structure as a function of latitude and distance? (Voyager at higher latitude and distance; function of cycle; difference A+ and A-) (3Di, o, SWI) - What is the 3D structure of the magnetic field in the quiet heliosphere? (3Di, o) • - What are the heliospheric signatures of the global magnetic field reversal in each 11-year cycle? (3Di, o) • How does the interstellar gas in the inner heliosphere change with the solar cycle? (3Do, i) • - How do the photospheric, coronal, and interplanetary magnetic fields relate to each other? (3Di, o) IHY Workshop April 2004Eberhard Möbius, UNH SSC

  7. Questions • - What is the high energy radiation environment and how does it change over time? (space weather) (3Do, i) • - What are the connections between GCRs and climate (3Do) • - What are the causes of GCR modulation? (3Do) • - What are the changes of the GCR spectrum? (3Do) • How does interplanetary acceleration change with solar cycle? (CS, 3Di) • What is the nature of the heliosphere near the TS? (TS, CS) • What are interplanetary signatures and effects of reconnection? (mag. f., composition) (3Di) • What are the properties of shocks? (CS, SWI) • What is the nature of heliospheric turbulence? (3Di,o, TS) IHY Workshop April 2004Eberhard Möbius, UNH SSC

  8. Small widely distributed Observatories • 1) Neutron Monitors (make use of all around the world, fill gaps; stability of neutron monitors) (John B.; Cliff L.?) • 2) µ-monitors 30 GeV; $100k (John B.) • 3) Low Frequency Radio Observatories (also EPO) (Justin K.) • 4) InterPlanetary Scintillation (IPS) • 5) Use of ground observatories for ISM absorption (E.M. ask Rosine Lallement)1, 2, 3, 4): encourage other countries to invest in order to get into front line research; assistance with blueprints and funds for workshops etc. possible3): PI projects with placing units in other countries IHY Workshop April 2004Eberhard Möbius, UNH SSC

  9. Education & Outreach • Theme:Head above the Atmosphere during the IGYHead out of our Home System with IHY • IHY Planetarium Show on the Heliosphere Voyager trip; ISM flow through system;Solar System through varying ISM • Use Radio Observatories for EducationNOT FINISHED!!!
