    The Interstellar 12CH+/13CH+ Ratio Towards the Scorpius OB1 Association
    We observed the λ 4232 Å CH+ interstellar line in the direction of the Sco OB 1 association (d ≃ 2 kpc) with the aim of detecting variations of the 12C/13C...

    The interstellar medium of quiescent galaxies and its evolution with time
    We characterise the basic far-IR properties and the gas mass fraction of massive (⟨log(M */M ⊙)⟩ ≈ 11.0) quiescent galaxies (QGs) and explore how these evolve...

    The intrinsic dispersion in the Faber-Jackson relation for early-type galaxies as function of the mass and redshift
    Context. It has been reported that the intrinsic dispersion at constant magnitude in the structural relations of early-type galaxies is a useful tool to study...

    The intrinsic shape of bulges in the CALIFA survey
    Context. The intrinsic shape of galactic bulges in nearby galaxies provides crucial information to separate bulge types. Aims: We aim to derive accurate...

    The ionised and molecular mass of post-common-envelope planetary nebulae. The missing mass problem
    Context. Most planetary nebulae (PNe) show beautiful, axisymmetric morphologies despite their progenitor stars being essentially spherical. Close binarity is...

    The ionized gas in the CALIFA early-type galaxies. I. Mapping two representative cases: NGC 6762 and NGC 5966
    As part of the ongoing CALIFA survey, we have conducted a thorough bidimensional analysis of the ionized gas in two E/S0 galaxies, NGC 6762 and NGC 5966, aiming...

    The ionized gas in the spiral galaxy NGC 3359. I. Photometry
    We combine Hα imaging and broad-band optical and NIR imaging over the face of the barred galaxy NGC 3359, obtained within the BARS program on the Canary Island...

    The iron abundance in four planetary nebulae
    We have observed the high excitation planetary nebulae NGC 7027, NGC 6543 and the low excitation planetaries Hu 2-1 and Cn 3-1 in the optical & near IR with the...

    The isotopic ^6Li/^7Li ratio in Centaurus X-4 and the origin of Li in X-ray binaries
    Context: Cool stars, companions to compact objects, are known to show Li abundances which are high compared to field stars of the same spectral type, which are...
