Rosetta papers with CBK PAN participation
Our research


The first is an overview paper by H. Sierks et al. entitled "On the nucleus structure and activity of comet 67P/Churyumov-Gerasimenko". The second gives a preliminary but detailed account of the features seen on the nucleus surface. This is by N. Thomas et al. and is entitled "The morphological diversity of comet 67P/Churyumov-Gerasimenko". The third describes OSIRIS imaging of dust grains in the surroundings of the nucleus by A. Rotundi et al. and is entitled "Dust measurements in the coma of comet 67P/Churyumov-Gerasimenko inbound to the Sun between 3.7 and 3.4 AU". The fourth by F.Cappacioni et al., entitled ,,The organic-rich surface of comet 67P/Churyumov-Gerasimenko as seen by VIRTIS/Rosetta'' describes types of substances seen in visible and infrared ranges of spectra obtained in different areas of cometary surface.

In the beginning of this year, scientists from the Laboratory for Solar System Physics and Astrophysics of the Space Research Centre, Polish Academy of Sciences (CBK PAN) developed a new model (see here) of the resonance radiation pressure acting on hydrogen atoms in the heliosphere.

Magnetic field strongly disturbs the motion of electrically charged particles in space but neutral atoms are insensitive to magnetic forces and consequently they move freely in all directions. This is true also for energetic neutral atoms (ENAs) in the heliosphere.

The smallest dust grains in the circumsolar dust cloud are the nanodust particles, i.e., the dust grains with the sizes of a few to a few tens millionth parts of millimeter. They are so small they include just several dozen thousands of atoms.

Interplanetary space is filled with magnetized plasma from the Sun (the solar wind) and interstellar gas, mainly hydrogen and helium, which continuously flows through the heliosphere. The interstellar atoms are ionized by extreme ultraviolet radiation and the solar wind. In result of ionization of the interstellar atoms, new ions in the solar wind are created.
