Determining which mergers lead to a particular outcome requires hydrodynamic simulations of the merging process. I give a brief overview of the current understanding of mergers and their end-products derived from simulations, and show how temperature, rather than density or mass, most strongly determines a merging binary's subsequent evolution. I then describe recent simulations that show mergers generate strong magnetic fields that could help drive a merger remnant to ignition.", "revisions": [ { "version": "v1", "updated": "2014-10-16T20:21:29.000Z" } ], "analyses": { "keywords": [ "wd binaries", "end-products", "mergers generate strong magnetic fields", "merging binarys subsequent evolution", "simulations" ], "tags": [ "conference paper" ], "note": { "typesetting": "TeX", "pages": 5, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015ASPC..493..563Z" } } }
