WebThe space-based asteroseismic revolution of red giant stars (de Ridder et al., 2009)spawned the realisation that oscillating giants would provide powerful ways to study the Milky Way (Miglio et al., 2009). The initial attempts of this asteroseismically-informed Galactic archaeology were made with CoRoT (e.g. Miglio et al., 2013; Anders WebEn astronomie, le red clump (en français grumeau rouge 1) désigne une zone du diagramme de Hertzsprung-Russell correspondant aux géantes rouges de population I — c'est-à-dire dont la métallicité est du même ordre que celle du Soleil — tirant leur énergie d'une part de la fusion de l' hélium en carbone 12 par réaction triple-alpha au cœur de l' … WebFind many great new & used options and get the best deals for 8 Card Red Parallel Lot 2024 Rookies & Stars Rachaad White, T.J.
