Detailed Abundances of the Solar Twins 16 Cygni A and B: Constraining Planet Formation Models
Detailed Abundances Solar Twins Constraining Planet Formation Models
2011/10/10
Results of a detailed abundance analysis of the solar twins 16 Cyg A and 16 Cyg B based on high-resolution, high signal-to-noise ratio echelle spectroscopy are presented. 16 Cyg B is known to host a g...
Solar twins in M67 : Evolutionary status and lithium abundance
Stars fundamental parameters – Stars abundances – Stars evolution – Stars interiors – Stars solar-type
2010/11/11
Aims. We determine the age and mass of the three best solar twin candidates in open cluster M67 through lithium evolutionary models.Methods. We computed a grid of evolutionary models with non-standard...
Astronomers could be on the cusp of detecting gravitational waves after four decades of trying, according to a team of Polish astrophysicists. They say that if current gravitational-wave detectors are...
