Well I've found the reason why:
the correct way (or the celanest way) to finish the node execution of a node is actually invoking the command:
$rosnode kill <node_name>
this will gently invoke the dispose in the node which among others release resources, dispose itself and "Disconnect from the Master"-- Ha! that is very important!
Since I can terminate the application (the node is an application too) by doing Control+ C, I've faced the issue that this method doesnt give a chance to the node to dispose itself properly, this is the reason why the zombie node is still visible when I do:
$rosnode list
anyways, the "zombie node" can be removed after calling a
$rosnode cleanup
