Magnetic Flux Determination in Late-Type DwarfsWe present a very preliminary and simplified analysis designed to measure photospheric magnetic fields in late-type stars, using the FeI 5247.06 Å and 5250.22 Å lines. We show how the use of the equivalent widths of the lines and differences in their depth can give a rapid estimation of the magnetic flux.Rípodas, P. et al.

Lithium, beryllium and boron - Observational constraints on primordial nucleosynthesisThe evidence bearing on the derivation of the primordial Li-7 abundance is summarized from observations of extremely metal-deficient stars in the galactic halo (Population II). Arguments, primarily observational, but supported theoretically, are presented to show that the Li-7 observed in warm halo subdwarfs has neither been supplemented by Li-7Beckman, J. E.
