In that case, just make jump drives require jump gates. The first ship(s) there will be the very long expensive mission(s) to build the first jump gate in 3rd-star's system.

The radiation was a good idea. The lose-contact-with-any-probe-sent was a good idea. The highly eccentric orbit was a good idea. You have options, which is nice; one or more could be in effect.
