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
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 [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
Simulation Results Image Simulation and Fresnel image simulation of the Object 15PC
Deeper observation at 150 pc If it is further away??
Thank you for you attention Any question are welcome Enjoy this!
