A multiwavelength abundance analysis of sdB stars using new model atmospheres

SdB stars provide a number of challenges in stellar astronomy. Their evolution along the extreme horizontal branch is well-known, but their formation remains a uncertain. Moreover, sdB stars show peculiar photospheric abundances due to diffusion processes and non-radial oscillation have been detecte...
