67P - Churyumov-Gerasimenko starpplanētu putekļi elektrostatiskā fragmentācija Fizika starpplanētu plazma

description

Pēc desmit ceļā pavadītiem gadiem un 2.5 gadiem pavadītiem hibernācijas periodā, Eiropas kosmosa aģentūras (angļu: European Space Agency, ESA) izpētes misija Rosetta uz komētu 67P/Churyumov-Gerasimenko ir pilnā datu ieguves režīmā, ar visiem tās 22 zinātniskajiem instrumentiem darbībā, lai izprastu mūsu Saules Sistēmas pirmsākumus. Komētas fizikālais raksturojums parāda, ka tās aptuvenais vidējais blīvums ir ~470 kg/m3 ar relatīvi mīkstu dabu un porozitāti no 70% līdz 80%. Šādām īpašībām apveltītas arī komētas mazākās daļiņas – putekļu graudi, ko parāda Rosettas COSIMA un MIDAS instrumenti - tām ir zema kohēzija tās viegli sadalās. Fizikālie procesi, kas iespējams apraksta šo sadalīšanos ir bakalaura darba galvenais izpētes objekts – Elektrostatiskā Fragmentācija.
