Scenarios for distributed sources of formaldehyde in the atmosphere of comet 67P/Churyumov-Gerasimenko
Abstract
The polymer of formaldehyde ((H2CO)n - polyoxymethylene - POM) has been tentatively detected in comet 1P/Halley by mass spectrometry with PICCA instrument onboard the Giotto spacecraft [1]. Although its detection has been questioned [2], this polymer could be the origin of distributed formaldehyde observed in the atmosphere of comet Halley and others [3]. We will present modelling results of the photo and thermal degradation of POM on grains in the environment of comet 67P/Churyumov-Gerasimenko, and discuss the extent to which distributed formaldehyde could be detected with Rosetta spacecraft observations in case POM is actually part of the nucleus component....
