    Abundances of Na, Mg and Al in stars with giant planets
    We present Na, Mg and Al abundances in a set of 98 stars with known giant planets, and in a comparison sample of 41 “single” stars. The results show that the [X...

    Accreting magnetars: a new type of high-mass X-ray binaries?
    The discovery of very slow pulsations (Pspin =5560 s) has solved the long-standing question of the nature of the compact object in the high-mass X-ray binary 4U...
