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 : 10-150 pc

UV Targets with scattering mechanism observations

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 : 100 -300 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

– 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

Numerical Profile

• Large arrays size and High resolution and High Dynamic Range

Simulation Results

• Image Simulation and Fresnel image simulation of the Object

• 15PC

Deeper observation at 150 pc

• If it is further away??
