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.
The mass-accretion rate is a crucial parameter for the study of the evolution of accretion discs around young solar-mass stars, and has an important impact for planet formation studies. The Taurus star forming region is rich in young stars, most of them of the T Tauri class, and many with a mass close to Solar. A variety of methodologies have been used in the past to measure mass accretion in samples of stars in Taurus, but despite being a general benchmark for star and, nowadays, planet formation studies, a comprehensive and systematic analysis of the Taurus T Tauri population, where the physical stellar and accretion properties are derived homogeneously and simultaneously, is still missing. To cover this gap, a pilot study of the stellar and accretion properties of seven very young stars in Taurus was carried out within the framework of the GIARPS High-resolution Observations of T Tauri stars (GHOsT) project.
