  • First measurement of the 34S(p,gamma)35Cl reaction rate through indirect methods for presolar nova grains 

    Gillespie, S; Parikh, A.; Barton, C; Faestermann, Thomas; José Pont, Jordi; Hertenberger, R.; Wirth, Hans Friedrich; de Séréville, N; Riley, J; Williams, M (AMER PHYSICAL SOC, 2017-08-02)
    Article
    Open Access
    Sulphur isotopic ratio measurements may help to establish the astrophysical sites in which certain presolar grains were formed. Nova model predictions of the 34S/32S ratio are, however, unreliable due to the lack of an ...
  • A Trojan horse approach to the production of 18F in Novae 

    la Cognata, M; Pizzone, R; José Pont, Jordi; Hernanz Carbó, Margarita; Cherubini, S; Gulino, M; Rapisarda, G; Spitaleri, C (2017-09-01)
    Article
    Open Access
    Crucial information on nova nucleosynthesis can be potentially inferred from ¿-ray signals powered by 18F decay. Therefore, the reaction network producing and destroying this radioactive isotope has been extensively studied ...
  • An efficient method for the static deflection analysis of an infinite beam on a nonlinear elastic foundation of one-way spring model 

    Ahmad, Fayyaz; Ullah, Malik Zaka; Jang, Taek Soo; Alaidarous, Eman (2017-10-03)
    Article
    Restricted access - publisher's policy
    An efficient numerical iterative method is constructed for the static deflection of an infinite beam on a nonlinear elastic foundation. The proposed iterative scheme consists of quasilinear method (QLM) and Green’s function ...
  • Updated evolutionary sequences for hydrogen-deficient white dwarfs 

    Camisassa, Maria E; Althaus, Leandro G.; Rohrmann, René D.; García-Berro Montilla, Enrique; Torres Gil, Santiago; Corsico, Alejandro H.; Wachlin, Felipe C. (Institute of Physics (IOP), 2017-04-10)
    Article
    Open Access
    We present a set of full evolutionary sequences for white dwarfs with hydrogen-deficient atmospheres. We take into account the evolutionary history of the progenitor stars, all the relevant energy sources involved in the ...
  • The population of white dwarf-main sequence binaries in the SDSS DR 12 

    Cojocaru, Elena Ruxandra; Rebassa Mansergas, Alberto; Torres Gil, Santiago; García-Berro Montilla, Enrique (2017-09-11)
    Article
    Open Access
    We present a Monte Carlo population synthesis study of white dwarf-main sequence (WD+MS) binaries in the Galactic disc aimed at reproducing the ensemble properties of the entire population observed by the Sloan Digital Sky ...
  • Frozen Jacobian multistep iterative method for solving nonlinear IVPs and BVPs 

    Ahmad, Fayyaz; Shafiq Ur, Rehman; Ullah, Malik Zaka; Aljahdali, Hani Moaiteq; Alshomrani, Ali Saleh; Carrasco, Juan A.; Ahmad, Shamshad (2017-01-01)
    Article
    Open Access
    In this paper, we present and illustrate a frozen Jacobian multistep iterative method to solve systems of nonlinear equations associated with initial value problems (IVPs) and boundary value problems (BVPs). We have used ...
  • The supersoft X-ray source in V5116 Sagittarii: I. the high resolution spectra 

    Sala Cladellas, Glòria; Ness, Jan-Uwe; Hernanz Carbó, Margarita; Greiner, Jochen (EDP Sciences, 2017-05-22)
    Article
    Open Access
    Context. Classical nova explosions occur on the surface of an accreting white dwarf in a binary system. After ejection of a fraction of the envelope and when the expanding shell becomes optically thin to X-rays, a bright ...
  • Measurement of key resonance states for the 40P(p,g)31S reaction rate, and the production of intermediate-mass elements in nova explosions 

    Kankainen, A; Woods, P.J.; Schatz, H.; Poxon-Pearson, T; Doherty, D.T.; Bader, V.; Baugher, T.; Bazin, D.; Brown, B.A.; Browne, J.; Estrade, A.; Gade, A.; José Pont, Jordi; Kontos, A.; Langer, C.; Lotay, G.; Meisel, Z.; Montes, F.; Noji, S.; Nunes, F.; Perdikakis, G.; Pereira, J.; Recchia, F.; Redpath, T.; Stroberg, R.; Scott, M.; Seweryniak, D.; Stevens, J.; Weisshaar, D.; Wimmer, K.; Zegers, R. (Elsevier, 2017-05-17)
    Article
    Open Access
    We report the first experimental constraints on spectroscopic factors and strengths of key resonances in the 30P(p, γ)31Sreaction critical for determining the production of intermediate-mass elements up to Ca in nova ejecta. ...

    Ahmad, Fayyaz; Tohidi, Emran; Carrasco, Juan A. (2016-03-01)
    Article
    Open Access
    We construct a novel multi-step iterative method for solving systems of nonlinear equations by introducing a parameter. to generalize the multi-step Newton method while keeping its order of convergence and computational ...
