Abstract:
The Jupiter family comet (JFC) 67P/Churyumov-Gerasimenko is the target
of the ESA's ROSETTA mission. Observational campaigns and
theoretical investigations were performed to characterise 67P/C-G in
terms of nucleus properties (e.g. size, surface colors, rotational
period), gas and dust production, and plasma environment in
preparation for the rendezvous with the spacecraft; however, there are
still open questions which need to be addressed. Our observations of
67P/C-G are important not only for good planning of the rendezvous of
the ROSETTA spacecraft with 67P/C-G, but also provide valuable
information on the basic physical properties of the nuclei of JFCs at
large heliocentric distances. Moreover, this information will also
help to identify to what extent 67P/C-G is a typical JFC.
Description:
We performed broad-band imaging of 67P/C-G in the visible wavelength
range between April 2004 and July 2007 at the ESO Very Large Telescope
(VLT) using the FORS2 instrument. At the time of the observations
67P/C-G was at heliocentric distance r=4.67AU and 4.63AU in April
2004 and July 2007, respectively and at phase angle alpha=2.1° in
April 2004 and 6.0° in July 2007.
