    The Tilt of the Fundamental Plane: Three-Quarters Structural Nonhomology, One-Quarter Stellar Population
    The variation of the mass-to-light M/L ratios of early-type galaxies as a function of their luminosities L is investigated. It is shown that the tilt β=0.27 (in...

    The tilted old Galactic disc and the position of the Sun
    With the use of data from COBE, IRAS and the Two-micron Galactic Survey (TMGS), we examine the effect on star counts and surface brightness maps of the position...

    The TOI-763 system: sub-Neptunes orbiting a Sun-like star
    We report the discovery of a planetary system orbiting TOI-763(aka CD-39 7945), a V = 10.2, high proper motion G-type dwarf star that was photometrically...

    The trace of a substantial assembly of massive E-S0 galaxies at 0.8 < z < 1.5 in galaxy number counts
    K-band galaxy number counts (GNCs) exhibit a slope change at K ˜ 17.5 mag not present in optical bands. To unveil the nature of this feature, we have derived...

    The Trace of the CNO Cycle in the Ring Nebula NGC 6888
    We present new results on the chemical composition of the Galactic ring nebula NGC 6888 surrounding the WN6(h) star WR136. The data are based on deep...

    The trans-Neptunian object size distribution at small sizes
    Aims: The aim of this work is to estimate the size distribution of small Trans-Neptunian objects. Methods: We simulate the irradiation and collisional processes...

    The transfer of polarized radiation in resonance lines with partial frequency redistribution, J-state interference, and arbitrary magnetic fields. A radiative transfer code and useful approximations
    Aims: We present the theoretical framework and numerical methods we have implemented to solve the problem of the generation and transfer of polarized radiation...

    The transfer of resonance line polarization with partial frequency redistribution and J-state interference. Theoretical approach and numerical methods
    The linear polarization signals produced by scattering processes in strong resonance lines are rich in information on the magnetic and thermal structure of the...
