    High and low Sérsic index bulges in Milky Way- and M31-like galaxies: origin and connection to the bar with TNG50
    We study bulge formation in MW/M31-like galaxies in a Λ-cold dark matter scenario, focusing on the origin of high- and low-Sersic index bulges. For this purpose...

    High frequency generation in the corona: Resonant cavities
    Aims: Null points are prominent magnetic field singularities in which the magnetic field strength strongly decreases in very small spatial scales. Around null...

    High spatial resolution Galactic 3D extinction mapping with IPHAS
    We present an algorithm (MEAD, for `Mapping Extinction Against Distance') which will determine intrinsic (r' - i') colour, extinction, and distance for early-A...

    High zenith angle observations of PKS 2155-304 with the MAGIC-I telescope
    Context. The high frequency peaked BL Lac PKS 2155-304 with a redshift of z = 0.116 was discovered in 1997 in the very high energy (VHE, E > 100 GeV) γ-ray...

    High-contrast optical imaging of companions: the case of the brown dwarf binary HD 130948 BC
    Context. High-contrast imaging at optical wavelengths is limited by the modest correction of conventional near-IR optimized AO systems. We take advantage of new...

    High-precision acoustic helium signatures in 18 low-mass low-luminosity red giants. Analysis from more than four years of Kepler observations
    Context. High-precision frequencies of acoustic modes in red giant stars are now available thanks to the long observing length and high quality of the light...

    High-Precision Near-Infrared Photometry of a Large Sample of Bright Stars Visible from the Northern Hemisphere
    We present the results of 8 yr of infrared photometric monitoring of a large sample of stars visible from Teide Observatory (Tenerife, Canary Islands). The...

    High-resolution infrared spectroscopy as a tool to detect false positives of transit search programs
    Context. Transit search programs such as CoRoT and Kepler now have the capability of detecting planets as small as the Earth. The detection of these planets...

    High-resolution spectroscopy of Boyajian's star during optical dimming events
    Boyajian's star is an apparently normal main-sequence F-type star with a very unusual light curve. The dipping activity of the star, discovered during the...
