TL;DR: In this paper, the authors report their observations of three transits of a Neptune-size planet with CARMENES in search of \het\ absorption, and they find that the mass loss rate, \mlr, is confined to a range of 3\,$\times\,10^{10}$\,\gs\ for $T$ = 6000\,K to 10\,€\times \,10€ 10€,€ 0.14$ at this wavelength, whereas a statistically valid detection can only be claimed for the night with higher S/
