Abstract

The boron abundance is derived for the young Orion solar-type member BD -05°1317 from Hubble Space Telescope Goddard High Resolution Spectrograph spectra of the B I esonance lines near 2497 Å. The abundance of log ∈(B) = 2.1 ± .2 is ∼0.6-0.7 dex below solar. As this young pre-main-sequence star has an undepleted lithium abundance, such a low boron abundance in a near-solar metallicity star is unexpected. No simple explanation apparently accounts for the low boron abundance observed for this star. A comparison of the boron and oxygen abundances in BD -05°1317 with those of other near-solar metallicity disk stars suggests that there might be a large scatter (∼0.8 dex) in the boron abundance at a given oxygen abundance. Such a scatter also has been reported in the literature for beryllium at a given metallicity.
