HD 86081 is a yellow-hued star in the equatorial constellation of Sextans. It has the proper name Bibhā, the Bengali form of a Sanskrit word meaning a bright beam of light. The star is named after the physicist Bibha Chowdhuri (1913-1991), who studied cosmic rays. This name was suggested in the 2019 NameExoWorlds campaign. With an apparent visual magnitude of 8.73, this star is too dim to be viewed with the naked eye but can be seen with a small telescope. It is located at a distance of approximately 340 light years from the Sun based on parallax, and is drifting further away with a radial velocity of +31 km/s.
