Simulated data for the study "Effects of Comet Encke's meteoroid stream on the seasonal variation of Mercury's Ca exosphere"

This .csv file contains simulated data related to the seasonal variation of calcium (Ca) in Mercury's exosphere, derived from Micro-Meteoroid Impact Vaporization (MMIV) processes. The model includes contributions from both the meteoroid background flux and cometary dust associated with comet 2P/Encke, evaluated over Mercury’s 2-year orbital period. 1 Column: TAA is the True Anomaly Angle of Mercury, where TAA=0° corresponds to the Mercury’s perihelion passage2 Column: Simulated seasonal Ca content in the exosphere over an odd Mercury year, due to meteoroid background flux including cometary contributions 3 Column: Simulated seasonal Ca content in the exosphere over an even Mercury year, due meteoroid background flux including cometary contributions 4 Column : mean exospheric Ca profile averaged over even and odd Mercury years5 Column: Simulated exospheric Ca profile assuming higher impact velocities from stream meteoroids6, 7 and 8 Columns: Simulated seasonal Ca profile due to the meteoroid background flux, including cometary contribution from three populations: young (1P, column 6), middle-age (2P, column 7) and old (3P, column 8); mass influx is 10 times higher than mean exospheric Ca profile (column 4) to approximately reproduce the observed Ca peaks 9 Column: Simulated seasonal Ca profile due from the meteoroid background flux, including all three populations of comet Encke; mass influx is 10 times higher than mean exospheric Ca profile (column 4) to approximately reproduce the observed Ca peaks 10 Column: Exospheric Ca profile assuming that the release of energetic Ca, generated through dissociative ionization processes followed by the neutralization of Ca⁺, is 50% of the total. The low-energy Ca component, generated by the photo-dissociation of the Ca-bearing molecules, constitutes the remaining 50%
