On the Possibilities of Existence of Photosynthetic Life around Alpha Centauri B %K %X We start with a brief description of the Alpha Centauri system and its main characteristics. Afterwards, we carry out calculations of several habitability metrics, such as the Π biological productivity and photosynthesis rates, in the oceans of the hypothetical exoplanets orbiting around Alpha Centauri B. By including a function of the temperature in a photosynthetic model, we describe the behavior of the metrics mentioned above for organisms with prokaryotic and eukaryotic cells that could potentially live in these exoplanets.   %U https://revistacubanadefisica.org/index.php/rcf/article/view?path= %J Revista Cubana de Física %0 Journal Article %& 114 %P 5 %V 36 %N 2 %@ 2224-7939 %8 2019-12-14 %7 2019-12-14
