    The Evolution of Massive Stars towards their Death: Rotation, Binarity and Mergers.
    Although they are rare and short-lived, massive stars play a major role in Universe. With their large luminosities, strong stellar winds and spectacular...

    The Evolution of Rotation and Magnetic Activity in 94 Aqr Aa from Asteroseismology with TESS
    Most previous efforts to calibrate how rotation and magnetic activity depend on stellar age and mass have relied on observations of clusters, where isochrones...

    The radial velocity of the sun as a star and the solar cycle
    Radial velocity measurements of the sun as a star using a resonant scattering spectrometer have been obtained at Izaña (Tenerife) during long observing seasons...

    The rotation of the solar core
    The solar p-mode spectrum of very low l has already been measured with high accuracy for a sufficiently long period of time to permit the search for solar cycle...

    The Rotation Speed of the Companion Star in Aquila X-1
    We have obtained medium resolution spectra of the neutron star X-ray transient Aql X-1 during quiescence. We determine the spectral type of the companion star...

    Understanding the Angular Momentum Evolution of T Tauri and Herbig Ae/Be Stars
    We investigate a sample of six Herbig Ae/Be stars belonging to the Orion OB1 association, as well as 73 low-mass objects, members of the σ Orionis cluster, in...
