在最近的观测中,我们发现了24颗主序星周围的热外黄尘辐射,它们的距离小于1000米,我们使用了H和K波段干涉测量法。由于星周尘埃和星星之间的高对比度和小角距离,直接观察这种尘埃成分是具有挑战性的。中红外干涉测量法提供了另一种探索热外黄道尘埃的方法。我们分析的L,MandN波段干涉签名,这种排放,以找到更强的约束的属性和起源的热exozodiacal尘埃。考虑到9个碎片光盘系统的参数推导出以前,我们在这些频带中的每一个模型的光盘。我们发现M波段具有探测热尘发射的最佳条件,其次是LandN波段。HD 22484(10 Tau)、HD 102647(β Leo)和HD 177724(β Aql)这三个系统中的热尘埃在可见度函数中显示出很强的信号,这甚至可以让人们限制尘埃的位置。特别是,中红外线的观测可以帮助确定尘埃是在升华半径处堆积,还是位于半径高达。此外,我们还利用超大望远镜干涉仪即将推出的中红外干涉仪多孔径中红外光谱实验(MATISSE)探索对热黄道外尘埃的观测。
Hot exozodiacal dust emission was detected in recent surveys around two dozen main-sequence stars at distances of less thanusing theH-andK-band interferometry. Due to the high contrast as well as the small angular distance between the circumstellar dust and the star, direct observation of this dust component is challenging. An alternative way to explore the hot exozodiacal dust is provided by mid-infrared interferometry. We analyse theL,MandNbands interferometric signature of this emission in order to find stronger constraints for the properties and the origin of the hot exozodiacal dust. Considering the parameters of nine debris disc systems derived previously, we model the discs in each of these bands. We find that theMband possesses the best conditions to detect hot dust emission, closely followed byLandNbands. The hot dust in three systems – HD 22484 (10 Tau), HD 102647 (β Leo) and HD 177724 (ζ Aql) – shows a strong signal in the visibility functions, which may even allow one to constrain the dust location. In particular, observations in the mid-infrared could help to determine whether the dust piles up at the sublimation radius or is located at radii up to. In addition, we explore observations of the hot exozodiacal dust with the upcoming mid-infrared interferometer Multi AperTure mid-Infrared SpectroScopic Experiment (MATISSE) at the Very Large Telescope Interferometer.
