D/H ratio in cometary water as a function of the active fraction
Date
The D/H ratio in cometary water as a function of the active fraction. The blue horizontal line corresponds to the Earth’s ocean value. The dashed-dotted line shows the expected ratio assuming two sources of water: D-rich (3.5×terrestrial) from the nucleus and terrestrial.
