15 Jun 2012: Lee et al (2009) assigned a mass 8.5 MJup to HW Vir (AB) c. Beuermann 2012v give a mass 65 ± 15 MJup; it would then not be a planet.
Nov. 2008: The object HW Vir (AB) c is named HW Vir 4 in Lee et al (2009)
Aug. 2024: Astrometric search partly validates this signal as planetary in origin.

Eclipsing binary star: M1 = 0.485 MSun, M2 = 0.142 MSun. P = 10084.58 ± 0.01 sec (Beuermann et al. 2012.
The mass for the system is the sum of the masses of the two components.
