They are created if and when the JVM crashes; they're analogous to a corefile, but contain a lot of Java-specific information. They're just text files, and you can delete them like you would any other files:

$ rm ~/hs_err_pid*.log
You can stop creating them by no longer crashing the JVM. Normally, such crashes are rare. Look at the files themselves in a text editor and they will contain some info about their origins.

These are Java crash (core) dump log files. Identify which Java process creates them by tracing and monitoring the PID.
