摘要:

我们提出了五个波段成像的织女星碎片光盘获得使用赫歇尔空间天文台。这些数据跨越70-500 μ m的波长范围,半高全宽角分辨率为5.6-36.9”。光盘是很好地解决在所有波段,与环结构可见70和160微米。产生了圆盘表面亮度的径向轮廓,并确定了圆盘半径为11”(~ 85 AU)。圆盘在整个波长范围内都有平滑的结构,这表明圆盘处于稳定状态,而不是最近两个大微行星碰撞造成的短暂结构。

英文摘要:

We present five band imaging of the Vega debris disc obtained using the Herschel Space Observatory. These data span a wavelength range of 70-500 um with full-width half-maximum angular resolutions of 5.6-36.9". The disc is well resolved in all bands, with the ring structure visible at 70 and 160 um. Radial profiles of the disc surface brightness are produced, and a disc radius of 11" (~ 85 AU) is determined. The disc is seen to have a smooth structure thoughout the entire wavelength range, suggesting that the disc is in a steady state, rather than being an ephemeral structure caused by the recent collision of two large planetesimals.
