Calcium/Sodium in the Milky Way . ... We map out calcium II sodium I absorption - corresponding to Fraunhofer H, K D lines - induced by both the interstellar medium and the circumgalactic medium of the Milky Way. ... We show that the abundance of sodium with respect to neutral hydrogen stays roughly constant in different environments, while that of calcium decreases with column density. ... Here we show the maps of calcium and sodium in the Milky Way based on the obtained data. ... Projects | ...
