http://www.robertoraddi.it/ My main research interests are evolved stars (i.e. white dwarfs and related science) and the fastest stars in our Milky Way (i.e. runaway and hypervelocity stars). Typically I work with large samples of ground-based and space-borne, photometric and spectroscopic observations, which I use for understanding the properties of stars I am interested in. As a member of the science team of the WEAVE project, which has built a new multi-fiber optical spectrograph at the William Herschel Telescope that is starting science operations in 2021, I will study the largest sample of evolved stars (~100,000 white dwarfs and related objects) in the northern hemisphere.
