abstract
Pre-main sequence (PMS) binaries and multiples enable critical tests of stellar models if masses, metallicities, and luminosities of the component stars are known. We have analyzed high-resolution, high signal-to-noise echelle spectra of the quadruple-star system HD 98800 and using spectrum synthesis, computed fits to the composite spectrum for a full range of plausible stellar parameters for the components. We consistently find that sub-solar metallicity yields fits with lower $\chi^2$ values, with an overall best-fit of $[M/H] = -0.20\pm0.10$. This metallicity appears to be consistent with PMS evolutionary tracks for the measured masses and luminosities of the components of HD 98800 but additional constraints on the system and modelling are needed.

Peering through the disc of HD 98800 BaBb. Precise timing predictions for the HD 98800 AaAb occultation
New RVs and multi-wavelength astrometry tighten the HD 98800 outer orbit by ~2×, yielding 5–15-day 1σ windows for the 2025–2031 disc occultation of AaAb.
