Scientific paper

We propose to study the dynamics of stellar transition regions by measuring the redshifts, indicative of downflows, in lines of C III, C IV, Si IV, and O IV.The energy balance and heating rates in stellar chromospheres and transition regions will be derived from an emission measure analysis of emission line fluxes and densities inferred from density sensitive line ratios. This proposal is a repeat of a failed repeat of a Cycle 1 observation of the C IV and Si IV of the G supergiant Beta Draconis (HOPR 66 and 120).
