Stellar Iron Abundances at the Galactic Center [PDF]

, 2000
We present measurements of [Fe/H] for six M supergiant stars and three giant stars within 0.5 pc of the Galactic Center (GC) and one M supergiant star within 30 pc of the GC. The results are based on high-resolution (lambda / Delta lambda =40,000) K-band

Finite-element study of residual stress distribution in Ti-6Al-4V alloy treated by laser shock peening with varying parameters

Fracture and Structural Integrity, 2022
Laser shock peening (LSP) is used to enhance surface quality of the metallic structures by the generation of compressive residual stresses on it. This work studies the effect of the main LSP parameters on residual stress fields by the finite-element ...
