A core dump is generated for debugging when a program crashes. Its a dump of the core memory of the system. You can't use emacs to edit or look at the file since its normally binary data, not ascii.

You can use a debugger to view the core file.
In Sun its dbx. Usage is dbx 'path/name of executable' 'path/name of core file'
In HP or AIX its gdb. Usage is gdb 'path/name of executable' 'path/name of core file'

Use man gdb or dbx for looking at more options.

Good Luck
