Relative Flux Density Variation in Saturn's Ring: Observations on the Outer Planets Binil Aryal

I present a Study of Relative Flux Density Variation in Saturn's ring using images taken Schmidt Telescope from National Observatory Nagarkot Nepal during the period form November 2008 to January 2010. The images of the Planet Saturn is captured with the help of the interface software AUTOSTAR SUITE 3.08 in FITS format then processed the images in the Software ALADIN2.5. The values of Relative Flux Density of 500*500[total 250,000]pixels are used for the study. I made an attempt to study the Flux Density variation along Saturn's ring form Eastern to Western region. I found that the total flux sometimes increases and decreases showing peak values at different regions along the ring. However,in the central region of the planet, we can see a fairly homogenous emission. No selective absorption or emission in noticed, I suspect that the on-going gravitational contraction is in about to saturate in the planet Saturn. In addition, I observed 2-D image of Saturn is divided into four regions: Eastern, Western, Northerninside and Southerninside. I took data of Relative Flux density associated with each pixel in these regions. The average value per pixel is found lie in the range form 115.31 to 249.13.
