Abstract Characterized by their close proximity to their host stars and scorching surface temperatures, hot super-Earths represent a readily accessible population that can be used to study the atmospheres, surfaces, and formation of rocky exoplanets in great detail. We present our radial velocity (RV) data analysis for the star TOI-539, in search of the transiting ultra-short-period hot super-Earth planet candidate TOI-539.01 detected by the Transiting Exoplanet Survey Satellite mission. We constrain the planetary mass of TOI-539.01 at the 2.3σ level. Additionally, we perform injection-recovery tests to determine mass detection limits for potential planets in the RV data set. We suggest an intensive RV campaign with higher precision observations to obtain a precise mass measurement and confirmation of TOI-539.01.
