What it does

Helps you understand the relationships between a star's properties and their observed exoplanet properties

How we built it

R, Python

Challenges we ran into

Huge Data Sparsity. Neither of us have much technical knowledge on coding, but we wanted to the implement the modeling frameworks we have learned, so we used generative AI to help turn our ideas/actions into code a computer could implement.

Accomplishments that we're proud of

Making a model in astronomy, when we don't have backgrounds in the field.

What we learned

Check if a dataset has non-sparse data if you want to do complete modeling (before you integrate it)

What's next for How do stars' properties help predict masses of planets?

Try to understand planets' other properties as a function of star properties.
