Ownership of a PhD Student's Research I am a PhD student in theoretical computer science. It is my understanding that if I work on a paper without my PhD advisor (which is common in my research area) and without any lab resources then that work is my own, and I can submit the paper where I choose. In particular, my advisor cannot force me to add them as a co-author if they have not contributed to the paper either intellectually or in the form of resources. Is this the most widely held view among scientists? What if the PhD student is an RA for 20 hours a week?
If your advisor hasn’t contributed anything to the paper intellectually then they can’t ethically put their name on a paper they didn’t contribute to. That has nothing to do with funding or RAships.

That said, what I described above is the ideal. Students are often under pressure to do what advisors say. Authorship is best discussed directly and if you have any issues you should speak with your advisor and establish standards in your group.
