    Role of host star variability in the detectability of planetary phase curves
    Phase curves, or the change in observed illumination of the planet as it orbits around its host star, help us to characterize their atmospheres. However, the...

    ROOSTER: a machine-learning analysis tool for Kepler stellar rotation periods
    In order to understand stellar evolution, it is crucial to efficiently determine stellar surface rotation periods. Indeed, while they are of great importance in...

    Rotation and magnetism of Kepler pulsating solar-like stars. Towards asteroseismically calibrated age-rotation relations
    Kepler ultra-high precision photometry of long and continuous observations provides a unique dataset in which surface rotation and variability can be studied...

    Rotation velocities of hot horizontal branch stars in the globular clusters NGC 1904, NGC 2808, NGC 6093, and NGC 7078: The database
    We present radial and rotation (v sin i) velocity measurements from UVES+VLT high resolution spectra of 61 stars in the blue horizontal branches (HB) of the...

    Rotational effects on the negative magnetic pressure instability
    Context. The surface layers of the Sun are strongly stratified. In the presence of turbulence with a weak mean magnetic field, a large-scale instability...

    Rotational modulation of the linear polarimetric variability of the cool dwarf TVLM 513-46546
    Aims: We aim to monitor the optical linear polarimetric signal of the magnetized, rapidly rotating M8.5 dwarf TVLM 513-46546. Methods: R- and I-band linear...

    Rotational synchronisation of B-type binaries in 30 Doradus
    The spin evolution of stars in close binary systems can be strongly affected by tides. We investigate the rotational synchronisation of the stellar components...

    Rotationally resolved spectroscopy of (20000) Varuna in the near-infrared
    Context. Models of the escape and retention of volatiles by minor icy objects exclude any presence of volatile ices on the surface of trans-Neptunian objects...

    Rotationally resolved spectroscopy of dwarf planet (136472) Makemake
    Context. Icy dwarf planets are key for studying the chemical and physical states of ices in the outer solar system. The study of secular and rotational...
