A Single Circumbinary Disk in the HD 98800 Quadruple System.

Koerner, Jensen, Cruz

    The Astrophysical Journal
    |March 23, 2000
    PubMed
    Summary

    Subarcsecond infrared imaging reveals a circumbinary disk around the HD 98800B binary, not a narrow ring. Dust emission indicates a disk extending beyond the binary

    Area of Science:

    • Astronomy and Astrophysics
    • Exoplanetary Science
    • Stellar Evolution

    Background:

    • HD 98800 is a young quadruple star system.
    • Previous observations suggested the presence of dust around one of the binary components.

    Purpose of the Study:

    • To investigate the spatial distribution and properties of dust around the HD 98800 system.
    • To determine if the dust forms a circumbinary disk or a narrow ring.

    Main Methods:

    • Subarcsecond thermal infrared imaging from 5 to 24.5 µm.
    • Analysis of infrared excess and silicate emission features.
    • Modeling of dust disk properties, including inner radius, radial extent, grain size, and mass.

    Main Results:

    • HD 98800B is the sole source of significant infrared excess.
    • A silicate emission feature is superimposed on the excess, peaking at 25 µm.
    • The dust temperature is approximately 150 K, indicating it lies beyond the binary's orbital separation.
    • Disk modeling favors a circumbinary disk with an inner radius of ~5 AU and radial extent of ~13 AU.

    Conclusions:

    • The dust in the HD 98800 system is best described as a circumbinary disk.
    • The findings challenge the narrow ring hypothesis for dust structures in young stellar systems.
