    LiteBIRD science goals and forecasts: constraining isotropic cosmic birefringence
    Cosmic birefringence (CB) is the rotation of the photons' linear polarisation plane during propagation. Such an effect is a tracer of parity-violating...

    LiteBIRD science goals and forecasts: improved full-sky reconstruction of the gravitational lensing potential through the combination of Planck and LiteBIRD data
    Cosmic microwave background (CMB) photons are deflected by large-scale structure through gravitational lensing. This secondary effect introduces higher-order...

    LiteBIRD science goals and forecasts: improving sensitivity to inflationary gravitational waves with multitracer delensing
    We estimate the efficiency of mitigating the lensing B-mode polarization, the so-called delensing, for the LiteBIRD experiment with multiple external data sets...

    LiteBIRD science goals and forecasts: primordial magnetic fields
    We present detailed forecasts for the constraints on the characteristics of primordial magnetic fields (PMFs) generated prior to recombination that will be...

    Lithium abundance and rotation of seismic solar analogues. Solar and stellar connection from Kepler and Hermes observations
    Context. Lithium abundance A(Li) and surface rotation are good diagnostic tools to probe the internal mixing and angular momentum transfer in stars. Aims: We...

    Lithium abundances and Li-7/Li-6 ratios in late-type population I field dwarfs
    Using the Coudé Echelle Spectrograph fed by the 1.4 m Coudé Auxiliary Telescope at ESO, La Silla, the authors have obtained a sequence of fourteen high...

    Lithium abundances and metallicities in stars near the main-sequence turnoff and a giant in M67
    The iron abundance of seven stars near the main-sequence (MS) turnoff and a giant in M67 are spectroscopically derived, and the results are discussed. The...

    Lithium Abundances in a Flux-Limited Sample of Galactic Carbon Stars
    Lithium abundances, or upper limits, have been derived for 161 galactic carbon stars, selected from the Two Micron Sky Survey, using high resolution, high...

    Lithium abundances in classical and weak T Tauri stars
    A study on the lithium abundance in 36 T Tauri stars (mass range 0.4-2.25 solar masses), partly based on high-dispersion spectra taken with the Isaac Newton...
