A reevaluation of the super-lithium-rich star in NGC 6633.

LAWS C. and GONZALEZ G.

Abstract (from CDS):

We present a new abundance analysis of the super-Li-rich star J37 and a comparison star in NGC 6633. We confirm the result of Deliyannis et al. that J37 has a Li abundance well above the meteoritic value, and we also confirm that Al, S, Si, Ca, Fe, and Ni are supersolar and that C is subsolar. We additionally find that Na, Sc, Ti are supersolar, while O is subsolar. The abundance pattern of metals in J37 is generally consistent with the bulk composition of the Earth. We propose that accretion of circumstellar matter is the best explanation for these abundance anomalies, although we cannot rule out a secondary contribution from diffusion.
