Quest for the Sun's siblings based on elemental abundances
Författare
Summary, in English
We present stellar parameters, stellar ages, and detailed elemental abundances for Na, Mg, Al, Si, Ca, Ti, Cr, Fe, and Ni for 32 solar sibling candidates. Technique of chemical tagging gives us a high probability that four stars might be from the same open cluster. Only one candidate HIP 40317 which has solar metallicity and age could be a solar sibling. We performed simulations of the Sun's birth cluster in analytical Galactic model and found that there is quite low probability to find solar siblings with radial velocity up to Vr = 34.2 km s-1.
