White dwarfs in the Gaia era


Inicio: 12:15h
Ponente: Alberto Rebassa Mansergas (Universitat Politècnica de Catalunya)
Lugar: Sala Alberto Lobo

The vast majority of stars will end, or have ended, their lives in the form of a white dwarf. These objects have the average size of the Earth, however they can be more massive than the Sun. This makes white dwarfs to be extremely dense and to have exceptional properties. In this talk we will study the…

The vast majority of stars will end, or have ended, their lives in the form of a white dwarf. These objects have the average size of the Earth, however they can be more massive than the Sun. This makes white dwarfs to be extremely dense and to have exceptional properties. In this talk we will study the physical characteristics of these exotic objects and we will see how the data provided by the Gaia satellite is helping us to significantly increase our understanding of white dwarfs.

THE 1908 TUNGUSKA EVENT: 111 YEARS AFTER, IT STILL MAKES YOU THINK


Inicio: 12:15h
Ponente: Luigi Foschini (INAF - Brera)
Lugar: Alberto Lobo

On June 30th, 1908, an explosion flattened more than two thousands square kilometres of Siberian taigà. During the following 111 years, several theories were proposed to explain the observed features. Basically, there is a general agreement on the collision of the Earth with a cosmic body, but still…

On June 30th, 1908, an explosion flattened more than two thousands square kilometres of Siberian taigà. During the following 111 years, several theories were proposed to explain the observed features. Basically, there is a general agreement on the collision of the Earth with a cosmic body, but still today there are doubts on the exact dynamics of the phenomenon and the nature of the body (comet or asteroid?). Particularly, I will address the atmospheric fragmentation and the possibility of a ground impact.
