Our galaxy is teeming with planets unlike those seen in our Solar System, including planets the size of Neptune and larger that orbit their host stars in just a few days. These hot, puffy planets are likely experiencing ongoing atmospheric evaporation. With the recently launched TESS satellite, we expected to discover thousands of new exoplanets, but before investing the evolution of their atmospheres, we need their masses. Stars wobble as their planets’ tug at them gravitationally, and with SALT/HRS we can measure this very small wobble and determine the masses of exoplanets. We are proposing to measure the masses for a few of the most exciting planets that we will discover with TESS.
