June 22 at Noon in the 2nd Floor Conference Room in Dearborn Speaker: Natalie Hinkel (Arizona State University) “Simulating Stellar Clusters; One Step at a Time” Every stellar cluster is affected by a unique set of environmental conditions where each star possesses a distinct chemical signature. In order to assess the consequences of individual ejecta on metal abundances, we are currently developing a simulation that will capture both the physical and chemical processes observed on cluster-mass scales. Working with a multidimensional, multi-physics code in FLASH, we used a "hybrid"-characteristics scheme for radiative transfer, ported from an earlier version of FLASH. We present initial results in which we calculate the degrees of ionization in a hydrodynamically-expanding Strömgren sphere, copacetic with similar models. The work here not only establishes a solid base for our simulation, but will ultimately be used to explore specific elemental ratios that have significant astrobiological implications. |
