The Chemical Composition of HE 1305+0132: A Carbon-Enhanced Metal-Poor Star with Enhanced Fluorine
نویسندگان
چکیده
The abundances of Fe, C, N, and Ba have been derived for the Carbon-Enhanced Metal-Poor star HE 1305+0132. The C and N abundances are typical of CEMP stars. The Ba abundance, derived for the first time for HE 1305+0132, is found to be enhanced relative to Fe, placing this star in the CEMP-s group. Combined with a previously derived highly enhanced abundance of F, the chemical composition of HE 1305+0132 strongly suggests that it has been polluted via mass transfer by a more evolved companion as it passed through its asymptotic giant branch phase.

Fluorine in a Carbon-enhanced Metal-poor Star
The fluorine abundance of the Carbon-Enhanced Metal-Poor (CEMP) star HE 1305+0132 has been derived by analysis of the molecular HF (1-0) R9 line at 2.3357 μm in a high-resolution (R = 50, 000) spectrum obtained with the Phoenix spectrometer and Gemini-South telescope. Our abundance analysis makes use of a CNO-enhanced ATLAS12 model atmosphere characterized by a metallicity and CNO enhancements ...
متن کاملFluorine in carbon-enhanced metal-poor stars: a binary scenario
Aims. A super-solar fluorine abundance was observed in the carbon-enhanced metal-poor (CEMP) star HE 1305+0132 ([F/Fe] = +2.90, [Fe/H] = −2.5). We propose that this observation can be explained using a binary model that involve mass transfer from an asymptotic giant branch (AGB) star companion and, based on this model, we predict F abundances in CEMP stars in general. We discuss wether F can be...
متن کاملModelling the evolution and nucleosynthesis of carbon-enhanced metal-poor stars
We present the results of binary population simulations of carbon-enhanced metalpoor (CEMP) stars. We show that nitrogen and fluorine are useful tracers of the origin of CEMP stars, and conclude that the observed paucity of very nitrogen-rich stars puts strong constraints on possible modifications of the initial mass function at low metallicity. The large number fraction of CEMP stars may inste...
متن کاملThermohaline mixing and gravitational settling in carbon-enhanced metal-poor stars
We investigate the formation of carbon-enhanced metal-poor (CEMP) stars via the scenario of mass transfer from a carbon-rich asymptotic giant branch primary to a low-mass companion in a binary system. We explore the extent to which material accreted from a companion star mixes with that of the recipient, focusing on the effects of thermohaline mixing and gravitational settling. We have created ...
متن کاملCarbon-enhanced metal-poor stars and thermohaline mixing
One possible scenario for the formation of carbon-enhanced metal-poor stars is the accretion of carbon-rich material from a binary companion which may no longer visible. It is generally assumed that the accreted material remains on the surface of the star and does not mix with the interior until first dredge-up. However, thermohaline mixing should mix the accreted material with the original ste...
