论文摘要
我们介绍了针对低和中等质量年轻恒星周围的星际磁盘中的中红外干涉测量调查的结果。我们的样本包括82个物体，包括T牛里星，Herbig AE星和年轻的爆发星。我们的主要结果是：1）TAuri恒星周围的磁盘与Herbig AE星星周围的磁盘相似，但是一旦我们说明了出色的光度，就会相对扩展。 2）从中红外发射区域的大小的分布中，我们发现内部尘埃圆孔可能存在于样品的大约一半。 3）我们对硅酸盐光谱特征的分析表明，内部$ \ sim $ 1 AU磁盘区域中的灰尘通常比外部区域更为处理。 4）与Herbig AE星相比，T Tauri恒星圆盘中的灰尘通常显示出N带谱的硅酸盐发射较弱，这可能表明磁盘结构的一般差异。我们的数据产品可在Vizier和以下网页上找到：http：//konkoly.hu/midi_atlas
We present our results from a mid-infrared interferometric survey targeted at the planet-forming region in the circumstellar disks around low- and intermediate-mass young stars. Our sample consist of 82 objects, including T Tauri stars, Herbig Ae stars, and young eruptive stars. Our main results are: 1) Disks around T Tauri stars are similar to those around Herbig Ae stars, but are relatively more extended once we account for stellar luminosity. 2) From the distribution of the sizes of the mid-infrared emitting region we find that inner dusty disk holes may be present in roughly half of the sample. 3) Our analysis of the silicate spectral feature reveals that the dust in the inner $\sim$1 au region of disks is generally more processed than that in the outer regions. 4) The dust in the disks of T Tauri stars typically show weaker silicate emission in the N band spectrum, compared to Herbig Ae stars, which may indicate a general difference in the disk structure.
