    Shock-induced polarized hydrogen emission lines in the Mira star o Ceti
    Context. In the spectra of variable pulsating stars, especially Mira stars, the detection of intense hydrogen emission lines has been explained by the presence...

    Short-term spectroscopic monitoring of two cool dwarfs with strong magnetic fields
    Context: There is now growing evidence that some brown dwarfs (BDs) have very strong magnetic fields, and yet their surface temperatures are so low that the...
