comet 45P/Honda-Mrkos-Pajdušáková Archives

Plot showing water active fraction vs CO2 abundance. Each color is a different comet. Each marker shape within the colors is a different heliocentric distance or relation to perihelion. The solid black line is a line of best fit that was calculated via orthogonal distance regression. It has an equation of y=(0.66±0.35)x+(-0.1±3.59). The green dashed lines are 1σ bounds on the best fit line. There is no significant correlation between active fraction and CO2 abundance for this sample of comets. -- astro-ph.EP

Inferring the CO2 Abundance in Comet 45P/Honda-Mrkos-Pajdušáková from [O I] Observations: Implications for the Source of Icy Grains in Cometary Comae

by Keith CowingJanuary 3, 2024

The study of cometary composition is important for understanding our solar system’s early evolutionary processes. Carbon dioxide (CO2) is a common hypervolatile in comets that can drive activity but is […]
