An international team of astronomers, including researchers from the IAC, have performed a unique cosmic test - measuring the mass of an ancient star using two entirely different methods, finding agreement to within just 1.4%. This result marks a milestone in our ability to determine the ages of old stars and use them as living fossils to study the Milky Way’s distant past. The team analysed the red giant in the binary system KIC 10001167 using two independent approaches: firstly, by measuring the brightness and radial velocity variations due to the orbital motion of the binary, and secondlyAdvertised on -

An international review article in which IAC researcher Jesús Falcón Barroso is a contributor, explains how the study of stellar populations in galaxies outside the Milky Way and the Local Group, using techniques which are called “extragalactic archaeology”, permits the reconstruction of the processes of formation and evolution of those galaxies. This article has been published in the Annual Review of Astronomy & Astrophysics , one of the most prestigious journals in this field, to which only five researchers of the IAC have contributed during the lifetime of the Institute.
