    K 3-22: a D-type symbiotic star
    A goal of the IPHAS survey is to determine the frequency and nature of emission-line sources in the Galactic plane. According to our selection criteria, K 3-22...

    K2-106, a system containing a metal-rich planet and a planet of lower density
    Aims: Planets in the mass range from 2 to 15 M⊕ are very diverse. Some of them have low densities, while others are very dense. By measuring the masses and...

    K2-111 b - a short period super-Earth transiting a metal poor, evolved old star
    Context. From a light curve acquired through the K2 space mission, the star K2-111(EPIC 210894022) has been identified as possibly orbited by a transiting...
