    An extensive spectroscopic time series of three Wolf-Rayet stars - I. The lifetime of large-scale structures in the wind of WR 134
    During the summer of 2013, a 4-month spectroscopic campaign took place to observe the variabilities in three Wolf-Rayet stars. The spectroscopic data have been...

    An Hermitian Method for the Solution of Polarized Radiative Transfer Problems
    Spectral synthesis calculations in stellar (magnetized) atmospheres are based on the solution of the radiative transfer equation (RTE) for polarized light. The...

    An Implicit Integral Method to Solve Selected Radiative Transfer Problems. IV. The Case of Spherical Geometry
    In the previous papers of this series, we introduced the implicit integral method (IIM) to solve those radiative transfer (RT) problems in which the source...

    An improved method for statistical studies of the internal kinematics of HII regions: the case of M83
    We present the integrated Hα emission line profile for 157 HII regions in the central 3.4 × 3.4 arcmin2 of the galaxy M83 (NGC 5236). Using the Fabry-Perot...

    An updated MILES stellar library and stellar population models
    Aims: We present a number of improvements to the MILES library and stellar population models. We correct some small errors in the radial velocities of the stars...

    Analysis of asymmetric p-mode profiles in GOLF data
    We show here evidence for the necessity of an asymmetric form in modelling the profile of an acoustic mode in the power spectral density. The analysis was...

    Analysis of Early Science observations with the CHaracterising ExOPlanets Satellite (CHEOPS) using PYCHEOPS
    CHEOPS (CHaracterising ExOPlanet Satellite) is an ESA S-class mission that observes bright stars at high cadence from low-Earth orbit. The main aim of the...

    Analysis of the solar cycle and core rotation using 15 years of Mark-I observations: 1984-1999 . I. The solar cycle
    High quality observations of the low-degree acoustic modes (p-modes) exist for almost two complete solar cycles using the solar spectrophotometer Mark-I...

    Analytic and numerical realizations of a disc galaxy
    Recent focus on the importance of cold, unshocked gas accretion in galaxy formation - not explicitly included in semi-analytic studies - motivates the following...
