基于FAST的FASHI调查，识别了662个近距HI源，发现71个新矮星系，揭示其光度、颜色、HI流量、质量及线宽等参数特征。

摘要：

我们从FAST的FASHI全天空HI调查中提取了662个近距（约16 Mpc）的HI检测源，并通过光学对应物进行视觉识别。这一检查发现了71个新矮星系。所有这些星系均为持续恒星形成的矮不规则星系。它们的中位参数为：视亮度g=17.8 mag，颜色(g-r)=0.29 mag，HI流量S_HI=718 mJy km/s，HI质量M_HI=3.7×10^7 M_太阳，以及HI线宽W_50=37 km/s。

英文摘要：

We extracted a list of 662 nearby (within $\sim16$ Mpc) HI-detection sources from the Five-hundred-meter Aperture Spherical radio Telescope (FAST) All Sky HI Survey (FASHI) and made a visual identification of them with optical counterpart. This inspection led to the discovery of 71 new dwarf galaxies. All of them are dwarf irregular galaxies with ongoing star formation. They are characterized by the following median parameters: visual magnitude of $g=17.8$ mag and color $(g-r)=0.29$ mag, HI-flux $S_\mathrm{HI}=718$ mJy km/s, HI-mass $M_\mathrm{HI}=3.7\times10^7$ $M_\odot$, as well as the HI line-width of $W_{50}=37$ km/s.
