What is HIP 78045
In Triangulum Australe, the small triangle of the southern sky, shines a white A-type star, hotter and more luminous than the Sun. Its light took some 215 years to reach us: it set out around 1810, in the midst of the independence processes of the American nations and while Goya was painting the horrors of the Peninsular War. A sharp, firm spark traces today one of the vertices of that humble southern figure.
