  1. Fresnel Targets in UV space mission Light Scattering from Dust Disks in active circumstellar, interstellar, galactic

  2. Summary • Fresnel Configurations • UV Observation Targets • Light Scattering • Numerical Profile Simulations • Simulation of Fresnel Imagery in a UV space Mission

  3. UV Observation • Why scattering light objects • Young stars have dust disks rotating around, mixed with gas. • Scattered light from dust ( gas does not scatter light) • Planets and young brown dwarfs can be detected with these formation. • Interesting?

  4. UV Observation Targets • High Energy Source • Stars, Active Galaxy etc • High Energy Particles • UV radiation Source or Scattered light source • Deep Space Targets • Galactic objects • Distant Objects : 10-150 pc

  5. UV Targets with scattering mechanism observations

  6. UV Targets with scattering mechanism observations • Jets and Young Stars Sample

  7. Accretion Disk of Dust in Circumstellar, interstllar and Galactic

  8. UV Observation • UV Observation for Fresnel Imaging • High Energy Sources • UV Wavelength : 100 -300 nm( 100,130,190) • High Angular Resolution Image in UV detection • Long focal distance

  9. Fresnel Configurations • Scenarios • Array Size configuration • UV Band : Wavelength

  10. Scattering of light principle • Scattered Light • Scattering function • Henyey- Greenstein scattering function

  11. Simulation Configurations • Energy: Solar Energy • Distance: 150 • Disks Ratio: Thin Disk model • Rin = 15 AU. • Rout = 200AU • Disk Ratio : Think disk Type • Fresnel Configuration • Array size : 20 m • Wavelengths: independent [125-350 nm, 1250°-3500°] • Resolution 0.7 mas

  12. Numerical Profile • Large arrays size and High resolution and High Dynamic Range

  13. Simulation Results • Image Simulation and Fresnel image simulation of the Object • 15PC

  14. Deeper observation at 150 pc • If it is further away??

  15. Thank you for you attention Any question are welcome Enjoy this!
