Descripción
Line-of-sight velocity fields in an irregular sunspot (NOAA 8990) have been determined from Stokes-I spectra of the line Fe I 630.15 nm, obtained with the La Palma Stokes Polarimeter at the Swedish Vacuum Solar Telescope on May 13, 2000. We show and discuss the resulting velocity maps and asymmetry of the Fe I line.

    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
