  • Study of the X-ray properties of the neutron star binary 4U 1728-34 from the soft-to-hard state 

    Wang, Yanan; Méndez, Mariano; Altamirano, Diego; Zhang, Guobao; Belloni, Tomaso M.; Martínez Ribeiro, Evandro; Linares Alegret, Manuel; Sanna, Andrea; Motta, Sara Elisa; Tomsick, John A. (Oxford University Press, 2019-01-16)
    Article
    Open Access
    We studied five XMM–Newton observations of the neutron star binary 4U 1728–34 covering the hard, intermediate and soft spectral states. By jointly fitting the spectra with several reflection models, we obtained an inclination ...
  • Interaction of hemispherical blast waves with inhomogeneous spheres: probing the collision of a supernova ejecta with a nearby companion star in the laboratory 

    García Senz, Domingo; Velarde, Pedro; Suzuki Vidal, Francisco; Stehlé, Chantal; Cotelo Ferreiro, Manuel; Portillo García, David; Plewa, Tomasz; Pak, Arthur (Institute of Physics (IOP), 2019-02-01)
    Article
    Open Access
    Past laboratory experiments at high energy density have provided insights into the physics of supernovae, supernovaremnants, and the destruction of interstellar clouds. In a typical experimental setting, a laser-driven ...
  • Dense matter with eXTP 

    Yu, WenFei; Poutanen, Juri; Zhang, Shu; Linares Alegret, Manuel (2019-02-01)
    Article
    Open Access
    In this White Paper we present the potential of the Enhanced X-ray Timing and Polarimetry (eXTP) mission for determining the nature of dense matter; neutron star cores host an extreme density regime which cannot be replicated ...
  • Random Forest identification of the thin disc, thick disc, and halo Gaia-DR2 white dwarf population 

    Torres Gil, Santiago; Cantero, C.; Rebassa Mansergas, Alberto; Skorobogatov, G.; Jiménez Esteban, F. M.; Solano Márquez, Enrique (Oxford University Press, 2019-03-13)
    Article
    Open Access
    Gaia-DR2 has provided an unprecedented number of white dwarf candidates of ourGalaxy. In particular, it is estimated thatGaia-DR2 has observed nearly 400 000 ofthese objects and close to 18 000 up to 100 pc from the Sun. ...
  • The binary millisecond pulsar PSR J1023+0038-II. Optical spectroscopy 

    Shahbaz, T.; Linares Alegret, Manuel; Rodríguez Gil, Pablo; Casares, Jorge (Oxford University Press, 2019-09-01)
    Article
    Open Access
    We present time-resolved optical spectroscopy of the ‘redback’ binary millisecond pulsar system PSR¿J1023+0038 during both its radio pulsar (2009) and accretion disc states (2014 and 2016). We provide observational evidence ...
  • Crust cooling of the neutron star in Aql X-1: different depth and magnitude of shallow heating during similar accretion outbursts 

    Degenaar, Nathalie; Ootes, Laura; Page, Dany; Wijnands, Rudy; Parikh, Aastha S.; Homan, Jeroen; Cackett, Edward; Miller, Jon M.; Altamirano, Diego; Linares Alegret, Manuel (Oxford University Press, 2019-10-01)
    Article
    Open Access
    The structure and composition of the crust of neutron stars plays an important role in their thermal and magnetic evolution, hence in setting their observational properties. One way to study the properties of the crust of ...
  • Where are the double-degenerate progenitors of Type Ia supernovae? 

    Rebassa Mansergas, Alberto; Toonen, S.; Korol, V.; Torres Gil, Santiago (Oxford University Press, 2019-01-01)
    Article
    Open Access
    Double white dwarf binaries with merger timescales smaller than the Hubble time and with a total mass near the Chandrasekhar limit (i.e. classical Chandrasekhar population) or with high-mass primaries (i.e. sub-Chandrasekhar ...
  • Discovery of the first resolved triple white dwarf 

    Perpinyà Vallès, M.; Rebassa Mansergas, Alberto; Gänsicke, Boris T.; Toonen, S.; Hermes, J. J.; Gentile Fusillo, N. P.; Tremblay, P. E. (Oxford University Press, 2019-02-01)
    Article
    Open Access
    We report the discovery of J1953-1019, the first resolved triple white dwarf system. The triplet consists of an inner white dwarf binary and a wider companion. Using Gaia DR2 photometry and astrometry combined with our ...
  • Accurate mass and radius determinations of a cool subdwarf in an eclipsing binary 

    Rebassa Mansergas, Alberto; Parsons, Steven G.; Dhillon, Vikram S.; Ren, Juanjuan; Littlefair, Stuart P.; Marsh, Thomas R.; Torres Gil, Santiago (Springer Nature, 2019-04-08)
    Article
    Open Access
    Cool subdwarfs are metal-poor low-mass stars that formed during the early stages of the evolution of our Galaxy. Because they are relatively rare in the vicinity of the Sun, we know of few cool subdwarfs in the solar ...
  • J-PLUS: The javalambre photometric local universe survey 

    Cenarro Lagunas, Andrés Javier; Moles Villamate, Mariano; Cristóbal Hornillos, David; Rebassa Mansergas, Alberto (EDP Sciences, 2019-02-01)
    Article
    Open Access
    The Javalambre-Photometric Local Universe Survey (J-PLUS ) is an ongoing 12-band photometric optical survey, observing thousands of square degrees of the Northern hemisphere from the dedicated JAST/T80 telescope at the ...
  • 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
