On the Demographics of Exoplanet Host Stars

The NASA TESS mission has provided the community with a plethora of new exoplanet host stars. These bright, nearby stars have been examined in detail in a number of studies and it has been determined that nearly one-half of the solar-like stars are binary. Two recent papers which examined 700 TESS exoplanet hosts have provided stellar properties for the stars, both single and binary. Herein, we provide a quantitative look at some properties of the stars, particularly searching for differences between the single versus binary (primary) host stars. We also compare the properties of the binary (primary) host stars themselves.
