The latter have been usually studied only as radial pulsators; the presence, however, of fine-structure in the period-luminosity diagram of red variables in the Magellanic Clouds could result from the presence of non-radial oscillations, offering the potential of observational indexes based on non-radial oscillations also for luminous red giants. We present here the results of a first approach aiming to identify the origin of the sub-ridges in the sequence A of the LMC red variables.Acknowledgments: We acknowledge the support from the ERC Consolidator Grant funding scheme (project STARKEY, G.A. n. 615604).enPublisher Copyright: © 2017 The Authors, published by EDP Sciences.2017-09-0810.1051/epjconf/20171520600885029517184
