Outer Versus Inner Halo Globular Clusters: NGC 7492 Abundances

Judith G. Cohen, Jorge Melendez

We have carried out a detailed abundance analysis for 21 elements in a sample of four RGB stars in the outer halo globular cluster NGC 7492 (R{GC} 25 kpc); we find [Fe/H] = -1.82 d…

Abundances in a Large Sample of Stars in M3 and M13

Judith G. Cohen, Jorge Melendez

We have carried out a detailed abundance analysis for 21 elements in a sample of 25 stars with a wide range in luminosity from luminous giants to stars near the main sequence turno…

Reappraising the Spite Lithium Plateau: Extremely Thin and Marginally Consistent with WMAP

Jorge Melendez, Ivan Ramirez

The lithium abundance in 62 halo dwarfs is determined from accurate equivalent widths reported in the literature and an improved infrared flux method (IRFM) temperature scale. The…

Abundances In Very Metal Poor Dwarf Stars

Judith G. Cohen, Norbert Christlieb, Andrew McWilliam +7

We discuss the detailed composition of 28 extremely metal-poor dwarfs, 22 of which are from the Hamburg/ESO Survey, based on Keck Echelle spectra. Our sample has a median [Fe/H] of…

Cooler and bigger than thought? Planetary host stellar parameters from the InfraRed Flux Method

Ivan Ramirez, Jorge Melendez

Effective temperatures and radii for 92 planet-hosting stars as determined from the InfraRed Flux Method (IRFM) are presented and compared with those given by other authors using d…
