Study of the inner corona and identification of the solar wind sources in active regions Vladimir Slemzin, and Alexander Urnov, Sergey Kuzin, FaridGoryaev (LPI), Louise Harra(MSSL), David Berghmans, Daniel Seaton (ROB), AnikDeGroof (ESA) SOTERIA Annual meeting , Leuven, May 30 - June1, 2011
1. Coronal rays in the inner corona R=1 - 3Rsun SPIRIT 2002 TESIS 2009
2. Outflows in HINODE XRT and EIS Sakao et al. 2007: 20-22 February 2007 HINODE/XRT observed outflows from edges of AR with V=100-170 km/s Doppler velocity Intensity Harra et al.2008: Hinode/EIS coronal outflows from active regions with V~ 50 km/s
3. Case study: August 1, 2009 Hinode/XRT EIS maps PFSS MF extrapolation TESIS, 1-8 August 2009
Properties of the outflow regions 20 lines with log T=5.4 – 6.3
Comparison with solar wind data Aug 9 Aug 2 Aug 5
4. Case study of AR 11112 on October 15 -21, 2010 HINODE/EIS observations of AR 11112 on October 15, 2010
Summary of the first results 1. Outflows detected by Doppler shifted spectral lines are accompanied by coronal signatures - fan rays at the disk and extended coronal rays (R>1.5 Rsun) at the limb 2. Fan rays and coronal rays represent different views of the same coronal structure co-aligned with open magnetic field lines 3. Middle term variations (hours) of the slow solar wind flux are correlated with latitudinal distribution of the integrated outflow flux in the AR. Studies of the solar wind sources and their modeling will be continued in new eHEROES project
