A Search for Li in Lithium-Poor Stars with Planets
Using high-resolution, high quality spectra we investigate the presence of Li in two lithium-poor stars that host extrasolar planetary systems. We present improved atomic and molecular line lists for the region in the vicinity of the lithium line at 6707.8 Å, and we produce an excellent fit to the solar spectrum. From line profile fitting, we find results consistent with no Li in either of the ...
متن کاملHabitability of super-Earth planets around other suns: models including Red Giant Branch evolution.
The unexpected diversity of exoplanets includes a growing number of super-Earth planets, i.e., exoplanets with masses of up to several Earth masses and a similar chemical and mineralogical composition as Earth. We present a thermal evolution model for a 10 Earth-mass planet orbiting a star like the Sun. Our model is based on the integrated system approach, which describes the photosynthetic bio...
متن کاملParent Stars of Extrasolar Planets. IX. Lithium Abundances
We compare the Li abundances of a sample of stars with planets discovered with the Doppler method to a sample of stars without detected planets. We prepared the samples by combining the Li abundances reported in several recent studies in a consistent way. Our results confirm recent claims that the Li abundances of stars with planets are smaller than those of stars without planets near the solar...
متن کاملThe Host Stars of Extrasolar Planets Have Normal Lithium Abundances
The lithium abundances of planet-harbouring stars have been compared with those of open clusters and field stars. Young (chromospherically active) and subgiant stars have been eliminated from the comparison because they are at different stages of evolution and Li processing to the planet-harbouring stars, and hence have systematically higher Li abundances. The analysis showed that the Li abunda...
متن کاملEntropy, neutrino physics, and the lithium problem—why stars with no lithium in early universe exist
We review how graviton initial energy values are linkable to possible order of the Lorentz gravitational violation. Counter intuitively, the greatest Lorentz gravitational violation would be at lower to moderate initial velocity value conditions due to pre inflationary conditions. .We assume with rapid build up of graviton energies , convergence to flat space, Lorentz invariance as gravitons , ...
