    Redshift-distance relations from type Ia supernova observations. New constraints on grey dust models
    Extinction due to intergalactic grey dust has been proposed as an alternative to accelerated expansion to account for the dimming of SnIa fluxes beyond z ≃ 0.5...

    Reduction of asteroidal appulses. First results in Bucharest
    The method presented is applied to asteroidal approaches to catalogue stars and occultations, and derives the minimum separation at conjunction and the...

    Reduction of the maximum mass-loss rate of OH/IR stars due to unnoticed binary interaction
    In 1981, the idea of a superwind that ends the life of cool giant stars was proposed1. Extreme oxygen-rich giants, OH/IR stars, develop superwinds with the...

    Refining the properties of the TOI-178 system with CHEOPS and TESS
    Context. The TOI-178 system consists of a nearby late K-dwarf transited by six planets in the super-Earth to mini-Neptune regime, with radii ranging from ~1.1...

    Regularities in frequency spacings of δ Scuti stars: the Kepler star KIC 9700322
    In the faint star KIC 9700322 observed by the Kepler satellite, 76 frequencies with amplitudes from 14 to 29 000 ppm were detected. The two dominant frequencies...
