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.

  • Laboratory evidence for co-condensed oxygen- and carbon-rich meteoritic stardust from nova outbursts 

    Haenecour, Pierre; Howe, Jane Y.; Zega, Thomas J.; Amari, Sachiko; Lodders, Katharina; José Pont, Jordi; Kaji, Kazutoshi; Sunaoshi, Takeshi; Atsushi, Muto (Springer Nature, 2019-04-29)
    Article
    Open Access
    Although their parent stars no longer exist, the isotopic and chemical compositions and microstructure of individual stardust grains identified in meteorites provide unique constraints on dust formation and thermodynamic ...
  • The 1989 and 2015 outbursts of V404 Cygni: a global study of wind-related optical features

  • The Gaia white dwarf population within 100 pc of the Sun 

    Torres Gil, Santiago; Rebassa Mansergas, Alberto; Jiménez Esteban, F. M.; Cantero, C.; Canals, Pere; Skorobogatov, G.; Solano, E (2018)
    Conference report
    Open Access
    The recent Gaia Data Release 2 has provided an unprecedented sample of the local white dwarf population. The high astrometric resolution and the photometry provided by Gaia allows to build a clean magnitude-color diagram ...
  • The difficulty of finding double-degenerate progenitors of type Ia supernovae 

    Rebassa Mansergas, Alberto; Toonen, S.; Korol, V.; Torres Gil, Santiago (2018)
    Conference report
    Open Access
    The double-degenerate progenitors of type Ia su- pernovae (SNIa) are double white dwarf binaries with a totalmass near the Chandrasekhar limit and with merger timescales smaller than the Hubble time. The fact that we ...
  • The age-metallicity relation from a sample of white dwarf-main sequence binarie 

    Rebassa Mansergas, Alberto; Anguiano, B.; García-Berro Montilla, Enrique; Freeman, K. C. (2018)
    Conference report
    Open Access
    The age-metallicity relation (AMR) is a fundamental observational constraint for un-derstanding how the Galactic disc formed and evolved chemically in time. However, there is not yet an agreement on the observational ...
  • The 26.3-h orbit and multiwavelength properties of the 'redback' millisecond pulsar PSR J1306-40 

    Linares Alegret, Manuel (Oxford University Press, 2018-01-01)
    Article
    Open Access
    We present the discovery of the variable optical and X-ray counterparts to the radio millisecond pulsar (MSP) PSR J1306–40, recently discovered by Keane et al. We find that both the optical and X-ray fluxes are modulated ...

    Pala, A. F.; Ederoclite, A; Gentile Fusillo, N. P.; Vázquez Ramió, H; Raddi, R; Abril, J; Gänsicke, Boris T.; Rebassa Mansergas, Alberto (2017)
    Conference report
    Open Access
    The study of Cataclysmic Variables (CVs) is crucial to test our understanding of binary evolution and its application to many astrophysical phenomena, such as short gamma-ray bursts, X-ray transients and, more important, ...
