HST observations of low-mass stars in IC 348

We investigate the low-mass population of the young cluster IC 348 down to the deuterium-burning limit, a fiducial boundary between brown dwarf and planetary mass objects, using...本研究针对年轻星团IC 348的低质量天体族群展开探究，将探测下限延伸至氘燃烧极限（deuterium-burning limit）——该极限是褐矮星（brown dwarf）与行星质量天体间的标准分界，本次研究采用……开展相关分析
