    A new dynamical modeling of the WASP-47 system with CHEOPS observations
    Among the hundreds of known hot Jupiters (HJs), only five have been found to have companions on short-period orbits. Within this rare class of multiple...

    A New Einstein Cross Gravitational Lens of a Lyman-break Galaxy
    We report the study of an “Einstein Cross” configuration first identified in a set of HST images by Cerny et al. Deep spectroscopic observations obtained at the...

    A new look inside planetary nebula LoTr 5: a long-period binary with hints of a possible third component
    LoTr 5 is a planetary nebula with an unusual long-period binary central star. As far as we know, the pair consists of a rapidly rotating G-type star and a hot...

    A new method for instrumental profile reconstruction of high-resolution spectrographs
    GJ 9827 is a bright, nearby K7V star orbited by two super-Earths and one mini-Neptune on close-in orbits. The system was first discovered using K2 data and then...

    A new method of measuring centre-of-mass velocities of radially pulsating stars from high-resolution spectroscopy
    We present a radial velocity analysis of 20 solar neighbourhood RR Lyrae and three Population II Cepheid variables. We obtained high-resolution, moderate-to...
