    The widest broadband transmission spectrum (0.38-1.71 μm) of HD 189733b from ground-based chromatic Rossiter-McLaughlin observations
    Multiband photometric transit observations (spectro-photometric) have been used mostly so far to retrieve broadband transmission spectra of transiting...

    The wind momentum-luminosity relationship of galactic A- and B-supergiants
    The Balmer lines of four A Ia-supergiants (spectral type A0 to A3) and fourteen B Ia and Ib-supergiants (spectral type B0 to B3) in the solar neighbourhood are...
