El Grup d' Astronomía i Astrofísica de la Universitat Politècnica de Catalunya (UPC) reuneix a un nombre reduit de persones interessades en una àmplia gama de temes de la Astronomía moderna. La història del grup va començar l'any 1995, just desprès de que alguns astrofísics perteneixents a dos departaments de física diferents (el departament de Física Aplicada, i el de Física i Enginyería Nuclear.) ajuntaran esforços per tal de crear un grup d'investigació competitiu en ciències de l'espai dins de la UPC. En la actualitat el GAA compta amb 7 investigadors permanents, a més de 6 estudiants doctorats i 11 estudiants postgraduats buscant aconseguir el seu doctorat. L'àrea principal d'actividad de la investigació del GAA pot ser classificada com Astrofísica Teórica. El tema és molt ampli, incloent-hi simulacions de computadora de les últimes etapes de la evolució estelar (l'enfriamient de les nanes blanques, AGBs, explosions de novas i supernovas, explosions de raigs X i física dels objectes compactes), estructura y dinàmica dels jets relacionats amb el PN i els objectes de l'Herbig-Haro i Cosmología. Alguns membres també estàn interessats en altres areas, incloent-hi estudis del comportament cinemàtic de estrelles en la vecindad Solar així com el diseny de la instrumentació que serà utilitzada per els satèlits científics.

    Article
    Open Access
    We conduct a population synthesis study of the common envelope evolution (CEE) of a white dwarf (WD) and an asymptotic giant branch (AGB) star and find that the potential number of type Ia supernovae (SNe Ia) from the core ...

    Article
    Open Access
    Multidimensional nucleosynthesis studies with hundreds of nuclei linked through thousands of nuclear processes are still computationally prohibitive. To date, most nucleosynthesis studies rely either on hydrostatic/hydrodynamic ...

    Article
    Open Access
    M dwarfs are prime targets in the hunt for habitable worlds around other stars. This is due to their abundance as well as their small radii and low masses and tempera- tures, which facilitate the detection of temperate, ...
