How to add more authorities in a running AuRa network?

Presently there is no way to add block producers to an active chain (that I am aware of) - you need to add this to your node to allow for it. You can add this functionality: here is a (presently out of date) example of a pallet to expose this via an extrinsic call: https://github.com/gautamdhameja/substrate-validator-set

Picking up this pallet and maintaining it as part of the devhub might be required, or some more minimal version of it.
