    Populations of rotating stars
    We will start by recalling the effects of rotation on stellar evolution and briefly explain its implementation in a stellar evolution code. We will present a...

    Position-dependent infrared spectroscopy of M82 - 100,000 Orion nebulae?
    It is reported that 8-13-micron spectra have been obtained at several positions across the extended emission region of M82. No major differences among the...

    Pre-main sequence lithium burning. 1: Weak T Tauri stars
    We report high-resolution spectroscopic observations for a sample of 38 T Tauri stars (TTS), complemented by UBVRI photometry of 13 TTS, and CCD VRI photometry...

    Pulsation in moderate rotating delta Scuti stars: The case of BN and BU CANCRI
    The results reported in this paper concern two delta Scuties in the Praesepe cluster, namely BN Cnc and BU Cnc, observed during the 1992 STEPHI 4 campaign. Five...

    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...
