Fundación Galileo Galilei - INAF Telescopio Nazionale Galileo 28°45'14.4N 17°53'20.6W 2387.2m A.S.L.

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 unveils an intriguing multi-planet system around HIP-99452

Thanks to 141 high-precision radial-velocity measurements obtained with HARPS-N within the GAPS (Global Architecture of Planetary Systems) consortium, a team of researchers led by Istituto Nazionale di Astrofisica (INAF) has discovered and characterized a particularly interesting exoplanetary system around the bright (V = 7.3 mag) and nearby (d = 20 pc) K-dwarf star HIP-99452 (TOI-5789).
The team focused on this star following the discovery of a transiting sub-Neptune-sized planet (with a radius smaller than Neptune’s) on an orbit of approximately 13 days by NASA’s Transiting Exoplanet Survey Satellite (TESS).

HARPS-N helps to discover and characterize an "inside out" planetary system around the star LHS 1903

Thanks to 108 precise radial-velocity measurements obtained with the high-resolution spectrograph HARPS-N, installed at the Telescopio Nazionale Galileo (between 2 October 2020 and 19 February 2023), together with data from ESA's CHEOPS satellite (Characterising ExOPlanet Satellite), astronomers were able to characterize the unusual planetary system known as LHS 1903.
