  text: "Context. Recent observational results from asteroseismic studies show that
    an important fraction of solar-like stars do not present detectable stochastically
    excited acoustic oscillations. This non-detectability seems to correlate with
    a high rotation rate in the convective envelope and a high surface magnetic activity.
    At the same time, the properties of stellar convection are affected by rotation
    and magnetism.\r\nAims. We investigate the role of rotation in the excitation
    of acoustic modes in the convective envelope of solar-like stars, to evaluate
    its impact on the energy injected in the oscillations.\r\nMethods. We derived
    theoretical prescriptions for the excitation of acoustic waves in the convective
    envelope of rotating solar-like stars. We adopted the rotating mixing-length Theory
    to model the influence of rotation on convection. We used the MESA stellar evolution
    code and the GYRE stellar oscillation code to estimate the power injected in the
    oscillations from our theoretical prescriptions.\r\nResults. We demonstrate that
    the power injected in the acoustic modes is insensitive to rotation if a Gaussian
    time-correlation function is assumed, while it can decrease by up to 60% for a
    Lorentzian time-correlation function, for a 20 Ω⊙ rotation rate. We show that
    the modification of the excitation rate by rotation depends not only on the rotation
    rate but also on the radial and angular orders of the considered oscillation mode.
    This result can allow for better constraints on the properties of stellar convection
    by studying observationally acoustic mode excitation.\r\nConclusions. These results
    demonstrate how important it is to take into account the modification of stellar
    convection by rotation when evaluating the amplitude of the stellar oscillations
    it stochastically excites. They open the path for understanding the large variety
    of observed acoustic-mode amplitudes at the surface of solar-like stars as a function
    of surface rotation rates."
