These meteorites are from asteroids formed at great distances from the Sun, containing the constituent elements of planets, and are known as Carbonaceous chondrites Vigrano (CV) and Karoonda (CK).&nbsp;<\/p>\n<p>The paper is based on the study of carbonate asteroids, so named because of their high organic matter content, which can be considered primitive because they contain solid materials that condensed around the Sun long before the Earth was formed. These asteroids are true fossils of the creation of the solid matter of our planetary system, as they cooled rapidly and their materials never melted.&nbsp;<\/p>\n<p>A group of scientists, including Safoura Tanbakouei -former researcher of the<a href=\"http:\/\/www.ieec.cat\/\"> Institute of Space Studies of Catalonia<\/a> (IEEC &mdash; Institut d&rsquo;Estudis Espacials de Catalunya) at the <a href=\"https:\/\/www.ice.csic.es\/en\/home\">Institute of Space Sciences<\/a> (ICE, CSIC)- and IEEC researcher at ICE Josep M. Trigo, have been studying the mineral content and reflective properties of these two groups of meteorites for ten years. These groups of chondrites have undergone a significant degree of metamorphism and fracture due to their exposure to collisions.&nbsp;<\/p>\n<p>The published paper explores a scenario in which the meteorites have their origin in the same asteroid, but evolved differently as a result of an impact that generated large fragments.&nbsp;<\/p>\n<p><img decoding=\"async\" alt=\"\" src=\"https:\/\/i.imgur.com\/eVk9UHm.jpg\" style=\"height:509px; margin-bottom:0px; margin-left:0px; margin-right:0px; margin-top:0px; width:765px\" \/><em>Caption: A great impact could be the origin of the disintegration of an asteroid from which fragments could arise, generating the CV and CK chondrites.&nbsp;<br \/>\nCredits: Don Dixon.<\/em><\/p>\n<p>The study measures and compares the reflectance of these two groups of chondrites and points to a shared deposit from which the meteorites CV and CK evolved after one or several collisions.&nbsp;&nbsp;<\/p>\n<p>According to this scenario, the CV and CK chondrites may have arisen from a common asteroid (most likely the asteroid known as Eos) that disintegrated into several fragments. Thus, due to impacts, the two groups of meteorites evolved separately.<\/p>\n<p>This study concludes nearly a decade of research on Carbonaceous chondrites, as part of three projects in the Spanish plan for astronomy and astrophysics to study and recover meteorites and propose techniques for the possible future exploitation of parent asteroids.&nbsp;<\/p>\n<p><strong>Links<\/strong><\/p>\n<p>&#8211; <a href=\"http:\/\/www.ieec.cat\/\">IEEC<\/a><br \/>\n&#8211; <a href=\"https:\/\/www.ice.csic.es\/en\/inici\">ICE<\/a><\/p>\n<p><strong>More information<\/strong><\/p>\n<p>This research is presented in a paper entitled &ldquo;The Reflectance Spectra of CV-CK Carbonaceous chondrites from the Near Infrared to the Visible&rdquo;, by S Tanbakouei, JM Trigo-Rodr&iacute;guez et al., published in the <em><a href=\"https:\/\/academic.oup.com\/mnras\/advance-article\/doi\/10.1093\/mnras\/stab2146\/6332309?guestAccessKey=1a43a1c7-b45b-4018-8357-2f38ef55729c\">Monthly Notices of the Royal Astronomical Society (MNRAS)<\/a><\/em> on 30 July 2021.<\/p>\n<p>The Institute of Space Studies of Catalonia (IEEC&nbsp; &mdash; Institut d&rsquo;Estudis Espacials de Catalunya) promotes and coordinates space research and technology development in Catalonia for the benefit of society.
