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??
