Description
The IAC is currently developing two similar polarimeters, one for optical wavelengths and one for near infra-red wavelengths (1.5 mu m). Both instruments will provide spectra of the four Stokes parameters over 2D solar regions. The visible spectro-polarimeter will be operated at the Swedish Tower (La Palma), and it is being developed in collaboration with the Royal Swedish Academy of Sciences. We intend to take advantage of the excellent seeing conditions at this telescope, while maintaining high polarimetric precision. The IR polarimeter is being designed for the German VTT (Tenerife) which has better angular resolution in the near infra-red. This report describes the goals and technical solutions. It also briefs on the current status of the projects.

    Measuring Rotation Periods and Stellar Oscillations in Red Giants with TESS Data
    TESS is a powerful engine for studying stellar variability. However, it has been challenging to adopt methods used for other space missions, such as Kepler, to infer rotation periods and solar-like oscillation frequencies in TESS data. The availability of multiple sectors of data for most targets, improved stability, and the release of new
