Proton and neutrino spectra for millisecond magnetars (top), magnetar giant flares (middle) and jetted tidal disruptions (bottom). For millisecond magnetars, we compare B_p = 10¹⁴ G and B_p = 10¹⁵ G (green and red lines) for p_esc, low. For magnetar giant flares and jetted tidal disruptions, we compare p_esc, low and p_esc, high (blue and orange lines). Left column: spectra of purely accelerated protons escaping the acceleration process without photohadronic interactions (dotted lines) and protons escaping the flaring region (solid lines). Right column: neutrino spectra without and with secondary acceleration (thin and thick lines).
