In situ research of cometary chemistry began when measurements from the Giotto mission at
Comet 1P/Halley revealed the presence of complex organics in the coma. New telescopes …

This review presents our understanding of cometary dust at the end of 2017. For decades,
insight about the dust ejected by nuclei of comets had stemmed from remote observations …

ABSTRACT Our modern day Solar System has 4.6× 109 yr of evolution behind it with just a
few relics of its birth conditions remaining. Comets are thought to be some of the most …

In-situ study of comet 1P/Halley during its 1986 apparition revealed a surprising abundance
of organic coma species. It remained unclear, whether or not these species originated from …

This chapter reviews the estimates of the dust-to-gas and refractory-to-ice mass ratios
derived from Rosetta measurements in the lost materials and the nucleus of 67P/Churyumov …

To understand how phosphorus (P)-bearing molecules are formed in star-forming regions,
we have analysed the Atacama Large Millimeter/Submillimeter Array (ALMA) observations …

The international Rosetta mission was launched in 2004 and consists of the orbiter
spacecraft Rosetta and the lander Philae. The aim of the mission is to map the comet …

We present the analysis of≈ 100 molecular maps of the coma of comet 67P/Churyumov-
Gerasimenko that were obtained with the MIRO submillimeter radiotelescope on board the …

Outbursts occur commonly on comets with different frequencies and scales,. Despite
multiple observations suggesting various triggering processes,, the driving mechanism of …

Primitive objects like comets hold important information on the material that formed our solar
system. Several comets have been visited by spacecraft and many more have been …
