Comet water source from solar wind and electromagnetic activity

Not all water in the Solar System today could have formed here, researchers say.
26 September 2014
By reconstructing conditions in the disk of gas and dust in which the Solar System formed, scientists have concluded that the Earth and other planets must have inherited much of their water from the cloud of gas from which the Sun was born 4.6 billion years ago, instead of forming later. The authors say that such interstellar water would also be included in the formation of most other stellar systems, and perhaps of other Earth-like planets...........
But the interstellar clouds where Sun-like stars are currently forming — and thus, presumably, the material from which the Sun formed — have a higher proportion of heavy water compared to the current Solar System. This is because these clouds are subject to the continuous bombardment of cosmic rays, which tend to favour the inclusion of deuterium. Therefore, the authors concluded, the young Sun’s radiation was insufficient to account for the amount of heavy water seen in the Solar System today, and some must have existed before. They estimate that somewhere between 30% and 50% of the water in Earth’s oceans must be older than the Sun........
“If the disk can’t do it, that means we must have inherited some level of these very deuterium-enriched interstellar ices from the birth environment of the Sun,” says Cleeves. The study was published in Science on 25 September1.........
Ewine van Dishoeck, an astrochemist at the Leiden Observatory in the Netherlands, says that the study’s conclusions are based on good arguments but are still only theoretical. But confirmation could come next year, she adds, when the Atacama Large Millimeter Array, a radio telescope in Chile’s Atacama Desert, begins to study the chemical processes underlying the proportion of heavy water in protoplanetary disks.
