To  do  so,  we  exposed  several<br \/>\ncarbonaceous  chondrites  (CV  Allende,  COs  Lanc\u00e9<br \/>\nand Frontier Mountain 95002, CM Mighei, CI Alais,<br \/>\nand ungrouped Tagish Lake) to 40 keV He +  ions as a<br \/>\nsimulation of solar wind irradiation using fluences up<br \/>\nto  6.10 16   ions\/cm 2  (implantation  platform  IRMA  at<br \/>\nCSNSM Orsay). As a test for our new experimental<br \/>\nsetup,  we  also  studied  samples  of  olivine  and<br \/>\ndiopside.  We  confirm  the  reddening  and  darkening<br \/>\ntrends on S-type objects, but carbonaceous chondrites<br \/>\npresent a continuum of behaviors after ion irradiation<br \/>\nas a function of the initial albedo and carbon content:<br \/>\nfrom red to blue and from dark to bright. &#8220;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>C.
