    An automated system to classify stellar spectra - I
    Analyses of stellar spectra often begin with the determination of a number of parameters that define a model atmosphere. This work presents a prototype for an...

    An effective temperature calibration for solar type stars using equivalent width ratios. A fast and easy spectroscopic temperature estimation
    Aims: Precise determination of the stellar effective temperature of solar type stars is extremely important for astrophysics. We present an effective...

    An ever-present Gaia snail shell triggered by a dark matter wake
    We utilize a novel numerical technique to model star formation in cosmological simulations of galaxy formation - called SUPERSTARS - to simulate a Milky Way...

    An extension of Herschel's method for dense and extensive catalogues. Application to the determination of solar motion
    We present a way of handling and interpreting stellar proper motions, in which the idea of substituting them by great circles, proposed by Herschel in 1783...

    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...
