The "Fundación Galileo Galilei - INAF, Fundación Canaria" (FGG) is a Spanish no-profit institution constituted by "INAF", the Italian Institute of Astrophysics.
The FGG's aim is to promote the astrophysical research, as foreseen in the international agreement of May 26, 1979 ("Acuerdo de Cooperación en Materia de Astrofísica, B.O.E. Núm.161, 6 Jul 1979"), by managing and running the Telescopio Nazionale Galileo (TNG), a 3.58m optical/infrared telescope located in the Island of San Miguel de La Palma, together with its scientific, technical and administrative facilities.

HARPS-N and the sub-Neptune HD 77946 b
The principal investigator of this project, L. Palethorpe, together with her team, used high-precision radial velocity measurements from HARPS-N together with transit observations from NASA's TESS satellite and ESA's CHEOPS satellite to characterise a sub-Neptune around the star HD 77946 (Mstar = 1.17 Msun , Rstar = 1.31 Rsun). They found that HD 77946 b has a mass of 8.38 ± 1.32 Earth masses and a radius of 2.71 ± 0.09 Earth radii, placing it into the region of mass-radius space where there is confusion about its possible composition.
