Radiative transfer models of extremely carbon-rich AGB star VX And

Utilizing collected Star Dust data allows us to form a deeper understanding of interstellar bodies and how they are created and what they are created from. Using infrared spectroscopic data from the Infrared space Observatory (ISO) along with ancillary data from the SIMBAD, we have collated a Spectral Energy Distribution (SED) for the carbon star VX And, which is an especially carbon-rich star (C/O=1.76). The radiative transfer code DUSTY is used to determine the effects of different variables such as star temperature, dust temperature, chemical composition of dust, size of the dust shell, optical depth into the star dust, etc. on the SED produced from such a star. This carbon star’s dust seems especially rich in Amorphous Carbon, but is also composed to Iron and Silicon Carbide (SiC).
