We present a catalog of holes and shells in the neutral atomic hydrogen (\HI) of 41 gas-rich dwarf galaxies in LITTLE THINGS (Local Irregulars That Trace Luminosity Extremes, The \HI Nearby Galaxy Survey). We analyzed their properties as part of an investigation into the relation between star formation and structures and kinematics in the \HI of small galaxies. We confirmed 306 holes between 38 pc (our resolution limit) and 2.3 kpc, with expansion velocities up to 30 \kms. The global star formation rates measured by \Ha and FUV emission are consistent with those estimated from the energy required to create the cataloged holes in our sample. Although we found no obvious correlation between global star-formation rates and the \HI surface and volume porosities of our sample, two of the four lowest porosity galaxies and the two highest porosity galaxies have no recent star formation as measured by \Ha and FUV emission.

LITTLE THINGS 矮星系星际介质中的孔和壳目录

我们展示了 LITTLE THINGS（追踪光度极端的局域不规则星系，\HI 附近星系调查）中 41 个富含气体的矮星系的中性原子氢 (\HI) 中的孔和壳的目录。我们分析了它们的特性，作为研究小星系\HI 中恒星形成与结构和运动学之间关系的一部分。我们确认了 38 pc（我们的分辨率限制）和 2.3 kpc 之间的 306 个孔，膨胀速度高达 30 \kms。由 \Ha 和 FUV 发射测量的全球恒星形成率与根据在我们的样本中创建编目孔所需的能量估计的结果一致。尽管我们发现全球恒星形成率与样本的\HI 表面和体积孔隙率之间没有明显的相关性，
