    The HD 98800 quadruple pre-main sequence system Towards full orbital characterisation using long-baseline infrared interferometry
    (2021) Zuniga-Fernandez, S.; Olofsson, J.; Bayo, A.; Haubois, X.; Corral-Santana, J. M.; Lopera-Mejia, A.; Ronco, M. P.; Tokovinin, A.; Gallenne, A.; Kennedy, G. M.; Berger, J-P
    Context. HD 98800 is a young (similar to 10 Myr old) and nearby (similar to 45 pc) quadruple system, composed of two spectroscopic binaries orbiting around each other (AaAb and BaBb), with a gas-rich disk in polar configuration around BaBb. While the orbital parameters of BaBb and AB are relatively well constrained, this is not the case for AaAb. A full characterisation of this quadruple system can provide insights on the formation of such a complex system.
