    An updated stellar census of the Quintuplet cluster
    Context. Found within the central molecular zone, the Quintuplet is one of the most massive young clusters in the Galaxy. As a consequence it offers the...

    An X-ray study of the open clusters NGC 2451 A and B
    We have conducted a detailed study of the object NGC 2451, which actually consists of two different open clusters A and B along the same line of sight at 206 pc...

    An X-ray view of 82 LINERs with Chandra and XMM-Newton data
    We present the results of a homogeneous X-ray analysis for 82 nearby low-ionisation, narrow emission-line regions (LINERs) selected from the catalogue of...

    Analyses of anomalous lensing events detected from the UKIRT microlensing survey
    Aims. The United Kingdom Infrared Telescope (UKIRT) microlensing survey was conducted over four years, from 2016 to 2019, with the goal of serving as a...

    Analysing the evolution of the thermal and magnetic properties of an X-class flare in the low solar atmosphere
    We analysed the evolution of the spatial distribution and stratification of the physical parameters of the atmosphere of an X-class flare in the photosphere and...

    Analysing the structure of the bulge with Mira variables
    Context. The Galactic bulge at latitude 4 < |b|(deg) < 10 was claimed to show an X-shape, which means that stellar density distributions along the line of sight...

    Analysis and modeling of high temporal resolution spectroscopic observations of flares on AD Leonis
    We report the results of a high temporal resolution spectroscopic monitoring of the flare star AD Leo. During 4 nights, more than 600 spectra were taken in the...

    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 chemical abundances in planetary nebulae with [WC] central stars. I. Line intensities and physical conditions
    Context. Planetary nebulae (PNe) around Wolf-Rayet [WR] central stars ([WR]PNe) constitute a particular photoionized nebula class that represents about 10% of...
