  One can infer the orbital alignment of exoplanets with respect to the spin of
their host stars using the Rossiter-McLaughlin effect, thereby giving us the
chance to test planet formation and migration theories and improve our
understanding of the currently observed population. We analyze archival HARPS
and HARPS-N spectroscopic transit time series of six gas giant exoplanets on
short orbits, namely WASP-77 Ab, WASP-101b, WASP-103b, WASP-105b, WASP-120b and
WASP-131b. We find a moderately misaligned orbit for WASP-101b ($\lambda
=34\degree\ \pm$ 3) and a highly misaligned orbit for WASP-131b ($\lambda
=161\degree\ \pm$ 5), while the four remaining ones appear aligned: WASP-77 Ab
($\lambda =-8\degree\ ^{+19}_{-18}$), WASP-103b ($\lambda =2\degree\
^{+35}_{-36}$), WASP-105b ($\lambda =-14\degree\ ^{+28}_{-24}$), and WASP-120b
($\lambda =-2\degree\ \pm$ 4). For WASP-77 Ab, we were able to infer its true
orbital obliquity ($\Psi =48\degree\ ^{+22}_{-21}$). We additionally perform
transmission spectroscopy of the targets in search of strong atomic absorbers
in the exoatmospheres, but are unable to detect any features, most likely due
to the presence of high-altitude clouds or Rayleigh scattering muting the
strength of the features. Finally, we comment on future perspectives for
studying these targets with the upcoming space missions to investigate the
evolution and migration histories of these planets.
