A total of 782 asteroids were identified. The observations with all four filters (Y, J, H, Ks), available for 297 of these candidates, allow a reliable comparison with the laboratory data of howardite, eucrite, and diogenite meteorites.<br>We found that the majority of the basaltic candidates (\u2248 95%) are located in the inner main belt, while only 29 (\u2248 4%) and 8 (\u2248 1%) are located in the middle and outer main belt, respectively. A fraction of \u2248 33% from the V-type candidates is associated with the Vesta family (with respect to AstDyS). We also identified four middle main belt V-type candidates belonging to (15) Eunomia family, and another four low inclination ones corresponding to (135) Hertha.<br> We report differences between the color indices and albedo distributions of the V-type candidates located in the inner main belt compared to those from the middle and outer main belt. These results support the hypothesis of a different origin for the basaltic asteroids with a semi-major axis beyond 2.5 A.U. Furthermore, lithological differences are present between the vestoids and the inner low inclination basaltic asteroids.<br> The data allow us to estimate the unbiased distribution of basaltic asteroids across the main asteroid belt. We highlight that at least 80% of the ejected basaltic material from (4) Vesta is missing or is not yet detected because it is fragmented in sizes smaller than 1 km. &#8220;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Jad-Alexandru Mansour, Marcel Popescu, Julia de Le\u00f3n, Javier Licandro MNRAS 000, 1\u201313 (2019) PDF (OPEN ACCESS) &#8220;We aim to determine the distribution of basaltic asteroids (classified as V-types) based on the spectrophotometric data reported in&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[77,36,35,33,34,3256,186],"tags":[1854,4517,212,2108,498,1872,2134],"_links":{"self":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/20736"}],"collection":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=20736"}],"version-history":[{"count":1,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/20736\/revisions"}],"predecessor-version":[{"id":20737,"href":"https:\/\/karmaka.de\/index.php?rest_route=\/wp\/v2\/posts\/20736\/revisions\/20737"}],"wp:attachment":[{"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=20736"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=20736"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/karmaka.de\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=20736"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
