Title:
SUISEI - A Versatile Global Model of Comets with Applications to Small Bodies

Abstract:
SUISEI is a suite of computational tools have been developed over the past three decades and successfully applied to comets; including ComChem, a global, multi-fluid gas dynamics simulation with detailed chemical kinetics of the cometary coma; coupled with ComMHD, a 3-D model of the comet-solar wind interaction; ComDust, a model of comet dust evolution and interaction with gas; and ComNuc, a 3-D simulation of gas and heat flow within the porous sub-surface layers of the comet nucleus. The combination of these tools has resulted in an improved knowledge of chemical species that form in the comet’s coma and their relationship to native molecules that exist in the nucleus ices by analyzing space- and ground-based observations and in situ measurements by instrumentation onboard spacecraft missions. Cometary ions mix with the solar wind as pick-up ions, eventually transported to an extensive plasma tail that may persist to 1 AU and beyond. This model is especially timely with the recent encounter of ESA’s Rosetta spacecraft with Comet 67P/Churyumov-Gerasimenko which ended in September 2016. After a review of SUISEI, applications will be made to three cases: chemical recycling of HCN in cometary comae, the phosphorous inventory of comets, and the physical conditions of the near-sun small body, Phaethon.

Biography:
Daniel C. Boice is the President and Principal Scientist of Scientific Studies and Consulting in San Antonio, Texas (USA). He is a research astronomer specializing in computational astrophysics for the past 3 decades. His career started at the Los Alamos National Laboratory (Theoretical Division) and he spent 26 years as a Principal Scientist at Southwest Research Institute (San Antonio, Texas, USA). Through a joint appointment, he was an Associate Professor in the Physics/Astronomy Department at the University of Texas at San Antonio for 20 years. Recently, he spent one year as a visiting Professor at the Institute of Astronomy (IAG) at the University of São Paulo (Brazil). Dr. Boice holds MS and PhD degrees in Astronomy from New Mexico State University (USA). He has published more than 300 papers in journals, books and conference proceedings, including more than 70 papers in peer-reviewed journals indexed in the Web of Science – Journal Citation Reports. He has participated in the scientific committees of several international conferences and associations and serves as a reviewer in a wide range of international journals and grant proposals. Currently, his major research interests are in planetary science (especially comets) but he has worked on diverse topics, including laser propagation in diverse environments and being the co-discoverer of the urban heat island of San Antonio, TX. Dr. Boice continues to have a strong commitment to education, public outreach, and international scientific collaboration.
