    A new non-convex model of the binary asteroid (809) Lundia obtained with the SAGE modelling technique
    We present a new non-convex model of the binary asteroid (809) Lundia. A SAGE (Shaping Asteroids with Genetic Evolution) method using disc-integrated photometry...

    A new procedure for defining a homogenous line-list for solar-type stars
    Context. The homogenization of the stellar parameters is an important goal for large observational spectroscopic surveys, but it is very difficult to achieve it...

    A New Spin on Galactic Dust
    We present a new puzzle involving Galactic microwave emission and attempt to resolve it. On one hand, a cross-correlation analysis of the Wisconsin Hα Mapper...

    A new strategy for helioseismic inversions
    Helioseismic inversion techniques have been revealed as powerful tools for inferring the internal structure and dynamics of the Sun. One of the most popular...

    A novel framework for semi-Bayesian radial velocities through template matching
    Context. The ability to detect and characterise an increasing variety of exoplanets has been made possible by the continuous development of stable, high...

    A Novel Iterative Scheme for the Very Fast and Accurate Solution of Non-LTE Radiative Transfer Problems
    Iterative schemes based on Gauss-Seidel (G-S) and optimal successive over-relaxation (SOR) iteration are shown to provide a dramatic increase in the speed with...

    A numerical approach for modelling the polarisation signals of strong resonance lines with partial frequency redistribution: Applications to two-term atoms and plane-parallel atmospheres
    Aims. The main goal of this paper is to present an accurate and efficient numerical strategy for solving the radiative transfer problem for polarised radiation...

    A numerical study of interactions and stellar bars
    For several decades, it has been known that stellar bars in disc galaxies can be triggered by interactions, or by internal processes such as dynamical...

    A physically motivated definition for the size of galaxies in an era of ultradeep imaging
    Present-day multiwavelength deep imaging surveys allow to characterize the outskirts of galaxies with unprecedented precision. Taking advantage of this...
