Here, we present a high-resolution database of giant impacts for differentiated colliding bodies of iron\u2013silicate composition, with target masses ranging from 1\u00a0\u00d7\u00a010\u22124M\u2295\u00a0up to super-Earths (5\u00a0M\u2295). We vary the impactor-to-target mass ratio, core\u2013mantle (iron\u2013silicate) fraction, impact velocity, and impact angle. Strength in the form of friction is included in all simulations. We find that, due to strength, the collisions with bodies smaller than about 2\u00a0\u00d710\u22123M\u2295\u00a0can result in irregular shapes, compound-core structures, and captured binaries. We observe that the characteristic escaping velocity of smaller remnants (debris) is approximately half of the impact velocity, significantly faster than currently assumed in\u00a0N-body simulations of planet formation. Incorporating these results in\u00a0N-body planet formation studies would provide more realistic debris\u2013debris and debris\u2013planet interactions.", "description": "59, 20 p.", "publisher": { "@type": "Organization", "name": "IOP Publishing" }, "author": [ { "@type": "Person", "name": "Emsenhuber, Alexandre", "givenName": "Alexandre", "familyName": "Emsenhuber", "affiliation": [ { "@type": "Organization", "name": "Ludwig Maximillian University Munchen" } ] }, { "@type": "Person", "name": "Asphaug, Erik", "givenName": "Erik", "familyName": "Asphaug", "affiliation": [ { "@type": "Organization", "name": "NASA Ames Research Center" } ] }, { "@type": "Person", "name": "Cambioni, Saverio", "givenName": "Saverio", "familyName": "Cambioni", "identifier": { "@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0001-6294-4523", "url": "https://orcid.org/0000-0001-6294-4523" }, "affiliation": [ { "@type": "Organization", "name": "Massachusettes Institute of Technology" } ] }, { "@type": "Person", "name": "Gabriel, Travis S.
