dc.descriptionThis is dynamical computer simulation data generated via 2-Gyr runs of long-period comet production using the SCATR code. Included are the raw simulation results of comet production along with the python script ('fancyplotbuilder.py') needed to generate each figure in the main paper. Simulation set is divided into 1000 subsimulation directories that are co-added to comprise a single simulation. Also included are single-orbit backintegrations of all simulated LPCs.en_US
dc.description.abstractThe discovery probability of long-period comets (LPCs) passing near the Sun is highest during their first passage and then declines, or fades, during subsequent return passages. Comet fading is largely attributed to devolatilization and fragmentation via thermal processing within 2--3 au of the Sun (1 au being the Earth-Sun distance). Here our numerical simulations show that comet observing campaigns miss vast numbers of LPCs making returning passages through the Saturn region (near 10 au) because these comets fade during prior, even more distant passages exterior to Saturn and thus elude detection. Consequently, comet properties significantly evolve at solar distances much larger than previously considered, and this offers new insights into the physical and dynamical properties of LPCs, both near and far from Earth.en_US
