    HST confirmation of the lensed quasar J03.13.
    In order to definitely prove the claim by Claeskens et al. (1996A&A...305L...9C) that J03.13 is a doubly imaged quasar, WFPC2 direct imaging and FOS...

    HST grism spectroscopy of z ∼ 3 massive quiescent galaxies. Approaching the metamorphosis
    Tracing the emergence of the massive quiescent galaxy (QG) population requires the build-up of reliable quenched samples by distinguishing these systems from...

    Hubble Space Telescope-NICMOS Observations of M31'S Metal-Rich Globular Clusters and Their Surrounding Fields. I. Techniques
    Astronomers are always anxious to push their observations to the limit-basing results on objects at the detection threshold, spectral features barely stronger...

    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 binary Cepheids using the ``lucky imaging'' technique
    Detecting companions to Cepheids is difficult. In most cases the brightness of the pulsator masks the fainter secondary. Since Cepheids play a key role in...

    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...

    IC 2602: a lithium depletion boundary age and new candidate low-mass stellar members
    We report the results from a photometric and spectroscopic survey of ˜1.4 deg2 of the young open cluster IC 2602. Fourteen objects have been identified as...

    Identification of Neodymium in the Apogee H-Band Spectra
    We present the detection of 10 lines of singly ionized neodymium (Nd ii, Z = 60) in H-band spectra using observations from the SDSS-III Apache Point Observatory...
