Presentation Transcript

  1. Future solar missions(Based on the summary by R.A. Harrison) S. Kamio 2004.11.15

  2. St Andrews is a small town in countryside. It is known for…

  3. Aim of workshop- Latest theoretical ideas for coronal heating- Observational results (SOHO, Yohkoh, TRACE, and RHESSI)- Looking towards the future space missions 2004 September 6 - 9 University of St Andrews, UKhttp://www.soho15.org/

  4. Future solar missions • Demands for better spatial and temporal resolution(in terms of coronal heating)- small scale magnetic structures - wave or oscillation • “Golden age” continuesSolar-B (2006)STEREO (2006)Solar Dynamics Observatory (2008)Solar Orbiter (2013) • We should understand their capabilities and limitations to make a suitable observation plan

  5. Solar-B • SOT (Solar Optical Telescope)50cm aperture, diffraction limited (0.25” or 175km)Intensity and vector magnetic field measurement- Narrow band filter- Broad band filter- Spectrograph • XRT (X-Ray Telescope)Full or partial Sun, 1”Temperature range 0.5-20 MK • EIS (EUV Imaging Spectrometer)170-210Å and 250-290Å (mainly 1-10MK lines)Doppler velocity (2km/s at best)Temperature and Density Diagnostics Launch 2006 http://solar.nro.nao.ac.jp/solar-b/

  6. STEREO (Solar TErrestrial RElations Observatory) • Observe 3D structure of the Earth-directed CME(A pair of spacecraft) • Launch 2006 • EUV Imager (1.6”/pixel)Full Sun in 171Å, 195Å, 284Å, 304Å • CoronagraphCOR1 1.1 - 3.0RCOR2 2 - 15R • Heliospheric ImagerInterplanetary CME http://stereo.gsfc.nasa.gov/

  7. SDO (Solar Dynamics Observatory) • Observe fine magnetic structures • Launch 2008 • HMI (Helioseismic and Magnetic Imager)Full Sun Doppler velocity (1” resolution)Vector magnetic field measurement • High resolution imager (0.6”/pixel)7 EUV and 3 UV bandsFull Sun (FOV 41’ ) • EUV irradiance measurement http://sdo.gsfc.nasa.gov/

  8. Solar Orbiter • Getting close to the Sun (45R or 0.2AU) • Launch 2013 • Instruments (TBD)soft X-ray, visible lightEUV imager/spectrometer • High resolution0.5” = 70km (at 0.2AU) • Polar region observationLatitude up to 33 degree http://www.orbiter.rl.ac.uk/

  9. What’s next ? • No (approved) mission after 2013Solar Probe (NASA) ?Solar-C (JAXA) ? • We should clarify the desired features for the following mission

  10. Notice • Solar-B special sessionASJ meeting in Meisei Univ., Tokyo (2005 Mar 28 - 30)Abstract deadline: 2004 Dec 6Observation plan based on your results • SOT seminar @ Kwasan Library2004 December 7-8- SOT magnetograph- SOT operation- Data analysis(to be transmitted to Hida?)
