摘要
As pan of a RECONS (Research Consortium on Nearby Stars) effort to discover stars nearer than 10 pc, LHS 1565 (GJ 1061; V=13.03; M5.5 V) has been found to be only 3.7 pc from the Sun using a combination of photometric, spectroscopic, and trigonometric parallax work. It ranks as the twentieth closest stellar system and underscores the incompleteness of the nearby star sample, particularly for objects near the end of the main sequence. Ironically, this unassuming red dwarf provides a shocking reminder of how much we have vet to learn about even our nearest stellar neighbors. (C) 1997 American Astronomical Society.
