  1. 1. Ranking line-depth ratios for determining relative star temperatures in dwarfs

    University essay from Observationell astrofysik

    Abstract : The central line-depths of absorption lines depend upon stellar temperature. By dividing the central line-depth of such a line with a central line-depth independent of temperature, a thermometer of relative star temperatures is obtained in the form of a line-depth ratio (LDR), once it is related to an effective temperature scale.
