Description
The search for solar siblings has been particularly fruitful in the past
few years. At present, there are four plausible candidates reported in
the literature: HIP21158, HIP87382, HIP47399, and HIP92831. In this
study we conduct a search for solar siblings among the HARPS
high-resolution FGK dwarfs sample, which includes precise chemical
abundances and kinematics for 1111 stars. Using a new approach based on
chemical abundance trends with condensation temperature, kinematics, and
ages we found one (additional) potential solar sibling candidate:
HIP97507.
Based on observations collected at the La Silla Paranal Observatory, ESO
(Chile) with the HARPS spectrograph at the 3.6-m telescope (ESO runs ID
72.C-0488, 082.C-0212, and 085.C-0063).

Several spectroscopic analyses of stars with planets have recently been carried out. One of the most remarkable results is that planet-harbouring stars are on average more metal-rich than solar-type disc stars. Two main explanations have been suggested to link this metallicity excess with the presence of planets. The first of these, the “self
