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
Young Stars observation
6
Observation in UV
7
UV Targets with scattering mechanism observations
8
Jets and Young Stars Sample
9
Accretion Disk of Dust in Circumstellar, interstllar and Galactic
10
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
11
Fresnel Configurations Scenarios Array Size configuration UV Band : Wavelength
12
Scattering of light principle Scattered Light – Scattering function Henyey- Greenstein scattering function
13
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 [125-350 nm, 1250°-3500°] – Resolution 0.7 mas
14
Numerical Profile Large arrays size and High resolution and High Dynamic Range
15
Simulation Results Image Simulation and Fresnel image simulation of the object
16
Simulation Results Image Simulation and Fresnel image simulation of the Object 15PC
17
Deeper observation at 150 pc If it is further away??
