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

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

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?

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 : pc

Young Stars observation

Observation in UV

UV Targets with scattering mechanism observations

Jets and Young Stars Sample

Accretion Disk of Dust in Circumstellar, interstllar and Galactic

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

Fresnel Configurations Scenarios Array Size configuration UV Band : Wavelength

Scattering of light principle Scattered Light – Scattering function Henyey- Greenstein scattering function

Simulation Configurations Energy: Solar Energy Distance: 150 Disks Ratio: Thin Disk model – R in = 15 AU. – R out = 200AU – Disk Ratio : Think disk Type Fresnel Configuration Array size : 20 m – Wavelengths: independent [ nm, 1250°-3500°] – Resolution 0.7 mas

Numerical Profile Large arrays size and High resolution and High Dynamic Range

Simulation Results Image Simulation and Fresnel image simulation of the object

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

Deeper observation at 150 pc If it is further away??
