Hi and thanks in advance for any help. The book I am currently working on features a protagonist that is an astronomer, I was hoping those more knowledgeable then I could check the passage where she describes her work and make sure it doesn't sound like gibberish. much appreciated. "Though she did get tired of people asking her what she did for a living. The very long answer was that she used a lot of the principles of physics and mathematics to learn more about the universe. Her particular position was to gather data on a parameter study of the possibility of tidally triggered disc instability, which she believed could theoretically could lead to enhanced planetesimal formation in the outer regions of the protoplanetary disc and could therefore be relevant for the existence of Neptune. She was leading up to writing a scientific paper to present to the field. The short answer, how and possibly why Neptune existed."
