Cov kws tshawb fawb Lavxias tau txiav txim siab txiav txim siab tias cov hmoov av uas pom muaj nyob hauv Chaw Tshav Dav Hlau Thoob Ntiaj Teb (ISS) yog li cas.
Cov neeg ua haujlwm ntawm cheeb tsam Moscow Laboratory ntawm Neutron Physics. IM Frank ntawm Koom Haum Koom Tes rau Kev Tshawb Fawb Nuclear (JINR) tshuaj xyuas qhov muaj pes tsawg leeg ntawm cov hmoov av thiab, yog li ntawd, txheeb xyuas lub hauv paus tseem ceeb ntawm cov tshuaj keeb kwm.
Nws muab tawm tias cov hmoov av no tuaj yeem muaj ntau qhov chaw, suav nrog cov khoom ntawm lub cev cosmic.
"Feem ntau ntawm cov hnub qub yog chondrites [muaj chondrules - kheej kheej lossis elliptical formations ntawm feem ntau silicate muaj pes tsawg leeg]. Lawv suav txog li 85% ntawm tag nrho cov naj npawb ntawm meteorites, "Inga Zinkovskaya, tus thawj coj ntawm kev tshawb fawb txog kev ua kom muaj neutron thiab thov tshawb fawb ntawm JINR Laboratory ntawm Neutron Physics, hais rau Izvestia ntawv xov xwm.
Nws tau sau tseg tias lawv muaj qhov tshwj xeeb muaj pes tsawg leeg thiab piv ntawm cov khoom.
Raws li Zinkovskaya, cov kws tshaj lij tau kawm txog qhov sib piv ntawm cov ntsiab lus ntawm cov ntaub so ntswg uas muaj kab mob sib kis thiab sib piv lawv nrog cov yam ntxwv ntawm chondrites. Raws li qhov tshwm sim, nws tau txiav txim siab tias magnesium, silicon, hlau, uranium thiab thorium ntawm cov ntaub yog keeb kwm cosmic.
Cov kws tshawb fawb tseem pom tias qhov thib ob ntawm cov hmoov av yog qhov chaw nres tsheb lub cev nws tus kheej, thiab qhov thib peb yog cov hluav taws tshauv tshauv tuaj ntawm lub Ntiaj Teb. Nws muaj cov hlau barium, zirconium, rhenium, strontium, rubidium thiab lub ntiaj teb tsis tshua muaj pom nyob hauv ISS.
"Plua plav los ntawm ntau qhov chaw yog nyob hauv qhov chaw thiab sib haum rau saum npoo ntawm lub dav hlau hauv tib txoj kev ib yam li ntawm cov nplaim hauv ntiaj teb," suav nrog Zinkovskaya.
