Resumen:
The theory of coronal heating produced by nanoflares has been used to explain a broad variety of coronal observations. One of the basic premises of the theory is that coronal loops are formed by subresolution elementary magnetic strands that interact with each other, reconnecting and consequently heating the plasma. The theory also predicts the widespread presence of intense plasma flows along the heated strands. In this work, we use our recently developed nanoflare heating model (Lopez-Fuentes and Klimchuk, 2015, ApJ, 799, 128, and 2016, ApJ, 828, 86) to explore the presence of flows and the possible observational consequences they may have on spectral lines of known coronal ions. The summed radiative emission of strands at different temperatures and velocities would produce on these lines characteristic broadenings and Doppler shifts. From our model we construct synthetic lines and analyze their parameters for future comparison with actual coronal observations.
