A core file contains the current memory of a process when the process fails (see http://en.wikipedia.org/wiki/Core_file). In an ABAP system you will find most likely a dump with the title SYSTEM_CORE_DUMPED which corresponds to that core file.
you can find out which process this was by issuing
If you don´t need the core file for analysis you can safely delete it.
