Scientific paper

A small but significant amount of the 6^Li isotope has been detected in the old metal-poor star HD 84937. Following the standard model of stellar evolution, the presence of this fragile element in the star is not expected if the star is a dwarf. The classical parallax indicates that the star is a dwarf, challenging either the standard stellar model or the standard primordial nucleosynthesis model. The Hipparcos parallax solves the problem, indicating that the star is a subgiant, the existence of 6^Li is then in agreement with the standard model of stellar evolution.
