    Radiation forces and the formation of planetary systems
    The effect of the rotation and finite size of a stellar radiation source on dust particle orbits is examined. It is found that, for dust particles substantially...

    Revisiting the Red Giant Branch Hosts KOI-3886 and ι Draconis. Detailed Asteroseismic Modeling and Consolidated Stellar Parameters
    Asteroseismology is playing an increasingly important role in the characterization of red giant host stars and their planetary systems. Here, we conduct...

    Rotation of Solar Analogs Crossmatching Kepler and Gaia DR2
    A major obstacle to interpreting the rotation period distribution for main-sequence stars from Kepler mission data has been the lack of a precise evolutionary...

    Rotational velocities in Galactic OB stars: the Fourier transform revolution
    The application of the Fourier transform (FT) technique to high resolution spectra of OB-type stars has challenged our previous knowledge about stellar rotation...

    Rubidium-rich asymptotic giant branch stars in the Magellanic Clouds
    Asymptotic Giant Branch (AGB) stars are a principal source of gas and dust input into the interstellar medium, being an important driver of chemical evolution...

    Secondary Infall in the Seyfert’s Sextet: A Plausible Way Out of the Short Crossing Time Paradox
    We used integral field spectroscopy from CALIFA DR3 and multiwavelength publicly available data to investigate the star formation histories of galaxies in the...
