Descripción
The variation of the electron density with position in a selected group of bright giant extragalactic H II regions has been studied using long slit spectrophotometry at high spectral and spatial resolution. Density values for the ionized gas of the regions have been obtained from the measurement of the forbidden S II 6717, 6731 A ratio. It is concluded that the regions are not homogeneous; the density varies with position, with the zones of high density frequently associated to high surface brightness.

    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
