    Hubble Space Telescope study of resolved red giant stars in the outer halos of nearby dwarf starburst galaxies
    Context. Central starbursts in galaxies are an extreme example of ongoing galaxy evolution. The outer parts of galaxies contain a fossil record of galaxy...

    Hubble spectroscopy of LB-1: Comparison with B+black-hole and Be+stripped-star models
    Context. LB-1 (alias ALS 8775) has been proposed as either an X-ray dim B-type star plus black hole (B+BH) binary or a Be star plus an inflated stripped star...

    Hunting for anti-solar differentially rotating stars using the Rossby number. An application to the Kepler field
    Context. Anti-solar differential rotation profiles have been found for decades in numerical simulations of convective envelopes of solar-type stars. These...

    Hydrodynamic simulations of cool stellar atmospheres with MANCHA
    Context. Three-dimensional time-dependent simulations of stellar atmospheres are essential to study the surface of stars other than the Sun. These simulations...

    Hydrogenated amorphous carbon grains as an alternative carrier of the 9-13 μm plateau feature in the fullerene planetary nebula Tc 1
    Fullerenes have been observed in several astronomical objects since the discovery of C 60 in the mid-infrared (mid-IR) spectrum of the planetary nebula (PN) Tc...

    H{2}D+ line emission in Proto-Planetary Disks
    Context: Previous studies have indicated that the 372.4 GHz ground transition of ortho-H2D+ might be a powerful probe of Proto-Planetary Disks. The line could...

    Hα and He I absorption in HAT-P-32 b observed with CARMENES. Detection of Roche lobe overflow and mass loss
    We analyze two high-resolution spectral transit time series of the hot Jupiter HAT-P-32 b obtained with the CARMENES spectrograph. Our new XMM-Newton X-ray...

    Hα emission fluxes and lithium abundances of low-mass stars in the young open cluster IC 4665.
    As part of a long term effort to understand pre-main sequence Li burning, we have obtained high resolution spectroscopic observations of 14 late type stars (G0...
