The NSF-funded "Research Experience for Teachers" project provides teachers an opportunity to work on a current scientific or engineering research project. This paper will describe the development of a Python program as a further expansion of a previous mathematical model3 designed to simulate cometary data collected by the Green Bank Telescope (GBT). The program allows for user interaction to change parameters such as the comet's distance from the sun, the rate of production of gaseous outflows, lifetime of these gaseous particles and maximum limit for how many gas particles are generated. Furthermore this paper will present results of how students can write their own Python programming code to manipulate these parameters to generate velocity profiles of the out gassed chemical species.
Students should be enlightened that Science can be cross disciplinary. Several concepts in Chemistry: sublimation, electromagnetic spectrum, quantum mechanics, gas behavior and chemical kinetics play an important role in the formation of a comet cloud and how that cloud could be observed using radio astronomy. Chemical species such as HCN, CS and HCO+1 have been observed in cometary clouds. The chemical composition of the cloud and its size are a function of its distance from the sun and the radial location from the center of the comet cloud. High-school students at the Louisiana School for Math, Science and the Arts, LA will learn Python programming language to create a mathematical model of a cometary cloud. The students will have formulated models for rate of sublimation, rate of photo-dissociation, and velocity of gas particles as the fundamental framework to determine frequencies and intensities of the molecular spectra. The students will be able to manipulate their code to create various comet cloud scenarios as it might be observed by the GBT.
