Discovered in 2002 as exoplanet candidate, HD 33636 b was disproven as such by Bean et al. (2007) through HST astrometry providing a mass compatible with a M6 dwarf star (m = 0.14 ± 0.01 MSol).However Xiao et al. (2023) noted an inconsistency and proposed by combining RV and HG proper motion astrometry a smaller mass of 77.8-6.6+6.9 MJup.
Kiefer et al. (2024) refute the low-mass stellar nature confirming HD 33636 b as massive planet close to brown dwarf boundary.
