- Hi. I am working on a research paper for my high school and I am trying to calculate the mass of an exoplanet using the radial velocity values of its star. However, I am confused as to the binary mass function and what units you would use. I also wanted to know how you would interpret a radial velocity curve to calculate the mass of the exoplanet. Thank you

The paper I am using for my radial velocity values is the following (Table 4)

Hi. I am working on a research paper for my high school and I am trying to calculate the mass of KELT-8b using the radial velocity values of its star. However, I am confused as to the binary mass function and what units you would use. I was under the impression you would use solar masses however I am getting a mass of 3.48 solar masses which is nothing close to the mass they found in the paper. I also wanted to know how you would interpret a radial velocity curve to calculate the mass of the exoplanet because I figured maybe I found the radial velocity the wrong way. The way I did it was by taking an average of the peaks after graphing it against the time. Thank you
