CSUMS Final Presentation

In my final presentation for the CSUMS program on August 4, 2011, I discussed significant advancements in researching the brown dwarf desert, including challenges faced during the second session. Initially deadlocked due to a crucial but simple oversight regarding the Chabrier and Kroupa mass-generating equations, we were obtaining excessively low frequencies of solar mass stars. I've corrected corrupt graphs and am now ready to run primary simulations. Results indicate that the cumulative distribution functions (CDFs) and probability density functions (PDFs) of Kroupa and Chabrier show alignment, paving the way for future analysis.
