    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...

    Analysis of chemical abundances in planetary nebulae with [WC] central stars. II. Chemical abundances and the abundance discrepancy factor
    Aims: We present the abundance analysis of 12 planetary nebulae ionized by [WC]-type stars and weak-emission-line stars (wels) obtained from high-resolution...

    Analysis of new high-precision transit light curves of WASP-10 b: starspot occultations, small planetary radius, and high metallicity
    Context. The WASP-10 planetary system is intriguing because different values of radius have been reported for its transiting exoplanet. The host star exhibits...

    Analysis of possible anomalies in the QSO distribution of the Flesch & Hardcastle catalogue
    Aims:A recent catalogue by Flesch & Hardcastle presents two major anomalies in the spatial distribution of QSO candidates: i) an apparent excess of such objects...

    Analysis of the acoustic cut-off frequency and high-frequency peaks in six Kepler stars with stochastically excited pulsations
    Gravito-acoustic modes in the Sun and other stars propagate in resonant cavities with a frequency below a given limit known as the cut-off frequency. At higher...

    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 approximate seismology of transversely oscillating coronal loops
    Aims: We present an analytic approximate seismic inversion scheme for damped transverse coronal loop oscillations based on the thin tube and thin boundary...

    Analytical determination of coronal parameters using the period ratio P1/2P2
    Context: In transverse coronal loop oscillations, two periodicities have been measured simultaneously and are interpreted as the fundamental kink mode (with...
