    HADES RV Programme with HARPS-N at TNG. II. Data treatment and simulations<xref ref-type="fn" rid="FN1">
    Context. The distribution of exoplanets around low-mass stars is still not well understood. Such stars, however, present an excellent opportunity for reaching...

    HADES RV Programme with HARPS-N at TNG. VI. GJ 3942 b behind dominant activity signals
    Context. Short- to mid-term magnetic phenomena on the stellar surface of M-type stars can resemble the effects of planets in radial velocity data, and may also...

    HADES RV Programme with HARPS-N at TNG. XV. Planetary occurrence rates around early-M dwarfs
    Aims: We present the complete Bayesian statistical analysis of the HArps-n red Dwarf Exoplanet Survey (HADES), which monitored the radial velocities of a large...

    Harassment origin for kinematic substructures in dwarf elliptical galaxies?
    We have run high resolution N-body models simulating the encounter of a dwarf galaxy with a bright elliptical galaxy. The dwarf absorbs orbital angular momentum...

    Heating of the Magnetized Solar Chromosphere by Partial Ionization Effects
    In this paper, we study the heating of the magnetized solar chromosphere induced by the large fraction of neutral atoms present in this layer. The presence of...

    Height variation of the cutoff frequency in a sunspot umbra
    Context. In the solar atmosphere, the acoustic cutoff frequency is a local quantity that depends on atmospheric height. It separates low-frequency evanescent...

    Helioseismic holography of simulated sunspots: dependence of the travel time on magnetic field strength and Wilson depression
    Improving methods for determining the subsurface structure of sunspots from their seismic signature requires a better understanding of the interaction of waves...

    HELP project - a dreamed-of multiwavelength dataset for SED fitting: The influence of used models for the main physical properties of galaxies
    The Herschel Extragalactic Legacy Project (HELP) focuses to publish an astronomical multiwavelength catalogue of millions of objects over 1300 deg 2 of the...

    HerMES: detection of cosmic magnification of submillimetre galaxies using angular cross-correlation
    Cosmic magnification is due to the weak gravitational lensing of sources in the distant Universe by foreground large-scale structure leading to coherent changes...
