    Magnetic and Rotational Evolution of ρ CrB from Asteroseismology with TESS
    During the first half of main-sequence lifetimes, the evolution of rotation and magnetic activity in solar-type stars appears to be strongly coupled. Recent...

    Non-local thermodynamic equilibrium line profiles, rotation, and magnetic fields in seven DA white dwarfs
    Non-LTE calculations of H-alpha line profiles are presented and applied to derive rotational velocities from high-resolution spectra of DA white dwarfs. This...

    On the Characterization of GJ 504: A Magnetically Active Planet-host Star Observed by the Transiting Exoplanet Survey Satellite (TESS)
    We present the results of the analysis of the photometric data collected in long- and short-cadence mode by the Transiting Exoplanet Survey Satellite for GJ 504...

    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...

    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...

    Pre-main sequence lithium burning. 2: Pleiades low mass stars
    As part of a continuing study of the lithium abundances in pre-main sequence (PMS) low mass stars, we present Li observations for 13 K-type and 3 M-type stars...

    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...

    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...
