    TOI-519 b: A short-period substellar object around an M dwarf validated using multicolour photometry and phase curve analysis
    Context. We report the discovery of TOI-519 b (TIC 218795833), a transiting substellar object (R = 1.07 R Jup) orbiting a faint M dwarf (V = 17.35) on a 1.26 d...

    Towards a more complete sample of binary central stars of planetary nebulae with Gaia
    Context. Many if not most planetary nebulae (PNe) are now thought to be the outcome of binary evolutionary scenarios. However, only a few percent of the PNe in...
