    A Second Terrestrial Planet Orbiting the Nearby M Dwarf LHS 1140
    LHS 1140 is a nearby mid-M dwarf known to host a temperate rocky super-Earth (LHS 1140 b) on a 24.737-day orbit. Based on photometric observations by MEarth and...

    A second-order approximation to equatorial null geodesics in the Kerr metric - Application to light deflection in eclipsing compact binaries
    We present a second-order analytical expansion of null equatorial geodesics in the Kerr metric. The equations developed are applied to the study of light...

    A Second-order Moment of Microlensing Variability as a Novel Tool to Constrain Source Emission Size or Discrete Lens Demographics in Extragalactic Research
    We define a second-order moment of the observational differential microlensing curves that can be used to impose constraints on physical properties of lensed...

    A seesaw model for large neutrino masses in concordance with cosmology
    Cosmological constraints on the sum of the neutrino masses can be relaxed if the number density of active neutrinos is reduced compared to the standard scenario...

    A seismic and gravitationally bound double star observed by Kepler. Implication for the presence of a convective core
    Context. Solar-like oscillations have been observed by Kepler and CoRoT in many solar-type stars, thereby providing a way to probe stars using asteroseismology...
  • Publication
    A Seismic Signature of a Second Dynamo?
    The Sun is a variable star whose magnetic activity varies most perceptibly on a timescale of approximately 11 years. However, significant variation is also...
  • Publication
    A seismological analysis of δ Scuti stars in the Pleiades cluster
    A comparison between the oscillation frequencies of six multi-periodic δ Scuti stars of the Pleiades cluster and the eigenfrequencies of rotating stellar models...
  • Publication
    A semi-automatic procedure for abundance determination of A- and F-type stars
    A variety of physical processes leading to different types of pulsations and chemical compositions are observed between A- and F-type stars. To investigate the...

    A semi-empirical absolute flux calibration in the near infrared: Direct stellar diameters vs. IRFM determinations
    A new semi-empirical method to derive the absolute flux calibration in the near infrared (J,K,L and L' bands) is proposed. The method consists of the...
