    Radiation-induced forces on the orbits of dust particles around rotating stars
    The influence of rotation and finite size of the radiation source on the orbits of dust particles around stars is analyzed. It is found that there are physical...

    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...

    Spinning up the Surface: Evidence for Planetary Engulfment or Unexpected Angular Momentum Transport?
    In this paper, we report the potential detection of a nonmonotonic radial rotation profile in a low-mass lower-luminosity giant star. For most low- and...

    Stellar Rotation in the Gaia Era: Gyrochronology Under Inspection
    Rotation plays an important role in the life of stars and offers a potential diagnostic to infer their ages and that of their planets. This idea is known as...

    Supergiants with an Interesting Past
    Exciting things may have happened sometimes to the stars we see in the sky today. For example, Betelgeuse, also known as Alpha-Ori, an M-type red supergiant...

    Surface Rotation and Photometric Activity for Kepler Targets. II. G and F Main-sequence Stars and Cool Subgiant Stars
    Dark magnetic spots crossing the stellar disk lead to quasiperiodic brightness variations, which allow us to constrain stellar surface rotation and photometric...

    TESS Hunt for Young and Maturing Exoplanets (THYME). VII. Membership, Rotation, and Lithium in the Young Cluster Group-X and a New Young Exoplanet
    The public, all-sky surveys Gaia and TESS provide the ability to identify new young associations and determine their ages. These associations enable study of...

    TESS Hunt for Young and Maturing Exoplanets (THYME). XII. A Young Mini-Neptune on the Upper Edge of the Radius Valley in the Hyades Cluster
    We present the discovery and characterization of TOI-4364b, a young mini-Neptune in the tidal tails of the Hyades cluster, identified through TESS transit...
