  • Peering into the dark side: Magnesium lines establish a massive neutron star in PSR J2215+5135 

    Linares Alegret, Manuel; Shahbaz, T.; Casares, Jorge (Institute of Physics (IOP), 2018-05-20)
    Article
    Open Access
    New millisecond pulsars (MSPs) in compact binaries provide a good opportunity to search for the most massive neutron stars. Their main-sequence companion stars are often strongly irradiated by the pulsar, displacing the ...
  • On presolar stardust grains from CO classical novae 

    Iliadis, Christian; Downen, Lori N.; José Pont, Jordi; Nittler, Larry R.; Starrfield, Sumner (Institute of Physics (IOP), 2018-03-10)
    Article
    Open Access
    About 30%–40% of classical novae produce dust 20–100 days after the outburst, but no presolar stardust grains from classical novae have been unambiguously identified yet. Although several studies claimed a nova paternity ...
  • Breaking the habit: the peculiar 2016 eruption of the unique recurrent nova M31N 2008-12a 

    Henze, Martin; Darnley, Matt J.; Williams, Steven Charles; José Pont, Jordi (2018-04-10)

  • Using large spectroscopic surveys to test the double degenerate model for Type Ia supernovae 

    Breedt, E.; Steeghs, Dani; Marsh, T. R.; Gentile Fusillo, N. P.; Tremblay, P. E.; Green, M.; De Pasquale, S.; Hermes, J. J.; Gänsicke, Boris T.; Parsons, S. G.; Bours, M. C. P.; Longa Peña, P.; Rebassa Mansergas, Alberto (2017-02-20)
    Article
    Open Access
    An observational constraint on the contribution of double degenerates to Type Ia supernovae requires multiple radial velocity measurements of ideally thousands of white dwarfs. This is because only a small fraction of the ...
  • White dwarf dynamical interactions and fast optical transients 

    García-Berro Montilla, Enrique; Badenes Montoliu, Carlos; Aznar-Siguán, Gabriela; Loren Aguilar, Pablo (2017-07-01)
    Article
    Open Access
    Recent advances in time-domain astronomy have uncovered a new class of optical transients with time-scales shorter than typical supernovae and a wide range of peak luminosities. Several subtypes have been identified within ...
  • The critical binary star separation for a planetary system origin of white dwarf pollution 

    Veras, Dimitri; Xu, Siyi; Rebassa Mansergas, Alberto (2018-01-01)
    Article
    Open Access
    The atmospheres of between one quarter and one half of observed single white dwarfs in the Milky Way contain heavy element pollution from planetary debris. The pollution observed in white dwarfs in binary star systems is, ...
  • Spectroscopic study of Ne-20 + p reactions using the JENSA gas-jet target to constrain the astrophysical F-18(p, alpha)O-15 rate 

    Bardayan, D. W.; Chipps, Kelly A.; Ahn, S.; Blackmon, J. C.; Carmichael, S.; Greife, U.; José Pont, Jordi; Kontos, A.; Matos, Mireya E.; Thompson, Paul (AMER PHYSICAL SOC, 2017-11-16)
    Article
    Open Access
    The Jet Experiments in Nuclear Structure and Astrophysics (JENSA) gas-jet target was used to perform spectroscopic studies of 20Ne+p reactions. Levels in 19Ne were probed via the 20Ne(p,d)19Ne reaction to constrain the ...
  • The white dwarf binary pathways survey - II. radial velocities of 1453 FGK stars with white dwarf companions from LAMOST DR4 

    Rebassa Mansergas, Alberto; Ren, J. J.; Irawati, P.; García-Berro Montilla, Enrique; Parsons, S. G.; Schreiber, Mathias R.; Gänsicke, Boris T.; Rodríguez-Gil, Pablo; Liu, X.; Manser, C. J.; Nevado, S.P.; Jiménez Ibarra, Felipe; Costero, R.; Michel, R.; Zorotovic, Mónica; Hollands, M.; Han, Z.; Luo, A.; Hita Villaverde, Enrique F.; Kong, X. (2017-12-21)
    Article
    Open Access
    We present the second paper of a series of publications aiming at obtaining a better understanding regarding the nature of type Ia supernovae (SN Ia) progenitors by studying a large sample of detached F, G and K main-sequence ...
  • Testing the white dwarf mass-radius relationship with eclipsing binaries 

    Parsons, S. G.; Gänsicke, Boris T.; Marsh, T. R.; Ashley, R. P.; Bours, M. C. P.; Breedt, E.; Burleigh, M. R.; Copperwheat, C. M.; Dhillon, V. S.; Green, M.; Hardy, L. K.; Hermes, J. J.; Irawati, P.; Kerry, P.; Littlefair, S. P.; McAllister, M. J.; Rattanasoon, S.; Rebassa Mansergas, Alberto; Sahman, D. I.; Schreiber, Mathias R. (2017-10-01)
    Article
    Open Access
    We present high-precision, model-independent, mass and radius measurements for 16 white dwarfs in detached eclipsing binaries and combine these with previously published data to test the theoretical white dwarf mass–radius ...
  • The kinematics of the white dwarf population from the SDSS DR12 

    Anguiano, B.; Rebassa Mansergas, Alberto; García-Berro Montilla, Enrique; Torres Gil, Santiago; Freeman, K. C.; Zwitter, T. (2017-08-01)
    Article
    Open Access
    We use the Sloan Digital Sky Survey Data Release 12, which is the largest available white dwarf catalogue to date, to study the evolution of the kinematical properties of the population of white dwarfs in the Galactic disc. ...
  • One-armed spiral instability in double-degenerate post-merger accretion disks 

    kashyap, Rahul; Fisher, Robert T.; García-Berro Montilla, Enrique; Aznar-Siguán, Gabriela; Ji, Suoqing; Loren Aguilar, Pablo (2017-05-01)
    Article
    Open Access
    Increasing observational and theoretical evidence points to binary white dwarf (WD) mergers as the origin of some, if not most, normal Type Ia supernovae (SNe Ia). In this paper, we discuss the post-merger evolution of ...
