What is the current teaching of the Roman Catholic Church in regards to excommunication?

I am a member of the Lutheran Church Missouri Synod in the USA. I belong to a group discussing various theological issues. I am interested in the differences between our doctrine and Roman Catholic doctrine in regards to excommunication. Specifically, I read on [catholic.com](https://www.catholic.com/magazine/online-edition/excommunication-its-not-what-you-think) that the teaching on excommunication in the Roman Catholic Church changed in 1983. Specifically, at present, "being excommunicated does not mean one is no longer in the Church." According to that article, prior to 1983, an excommunicated individual "was kicked out of the Church". In order to understand this change, I have the following questions: 1) does being "kicked out of the Church" imply the loss of salvation, i.e., does it mean the person, unless reinstated, will go to Hell? 2) is it now the case that an excommunicated individual retains salvation, even if he/she remains unrepentant (that is, will not go to Hell)? 3) Does the answer to these questions relate to Roman Catholic doctrine concerning whether someone can be a member of the Church and yet not be saved (perhaps I am using the incorrect terminology, i.e "retain or loss of salvation" If so, please inform me of the correct term.) Let me emphasize that I am not interested in quarreling or demeaning the Roman Catholic Church. I only wish to obtain authoritative answers to our questions.
