When I did my undergraduate thesis, my project was a small part of a larger project being done by an MSc. student at the time. We obviously both had the same supervisor. This student completed his MSc. degree a few months ago, and I have since learned from him that he and his supervisor have submitted an article for publication. While the article has been accepted it hasn't actually been published yet. I was a little disappointed that I wasn't informed of it until now, and I'm also dismayed that my name wasn't included on the paper. While my contribution wasn't massive, I nevertheless contributed to the project. I mentioned this to my colleague and he said he wouldn't have an issue if my name was added. I'm not sure if I should bother bringing it up with my former supervisor. I don't know how the submission process works, and I also don't know if he will be surprised or offended in some way by this late request. I don't want to tarnish my professional relationship with this person and I just wanted some opinions as to whether or not I should request my name be added or simply not bother.
