Originally reported as exoplanet candidate, Kane et al. (2016) found that associated radial velocity signal was related to stellar activity. Original designation was "HD 99492 c" but this has been transferred to the new exoplanet candidate detected by Stalport et al. (2023), hence the unconfirmed planet is here labelled as "83 Leo Bd/HD 99492 d" for its putative separation.
