      Despite decades of intense efforts, many fundamental aspects of Type Ia supernovae (SNe Ia) remain elusive. One of the major open questions is whether the mass of an exploding white dwarf (WD) is close to the Chandrasekhar ...
    • Observational evidence for high neutronization in supernova remnants : implications for type Ia supernova progenitors 

      Martinez Rodriguez, Hector; Badenes Montoliu, Carles; Yamaguchi, H; Bravo Guil, Eduardo; Timmes, Frank; Miles, Broxton; Townsley, Dean; Piro, Anthony; Mori, Hideyuki; Andrews, Brett; Park, Sangwook (2017-06-28)
      Article
      Open Access
      The physical process whereby a carbon–oxygen white dwarf explodes as a Type Ia supernova (SN Ia) remains highly uncertain. The degree of neutronization in SN Ia ejecta holds clues to this process because it depends on the ...
    • The origin of the iron-rich knot in Tycho's supernova remnant 

      Yamaguchi, H; Hughes, John P.; Badenes Montoliu, Carles; Bravo Guil, Eduardo; Seitenzahl, Ivo R.; Martinez Rodriguez, Hector; Park, Sangwook; Petre, Robert (2017-01-09)
      Article
      Open Access
      X-ray observations of supernova remnants (SNRs) allow us to investigate the chemical inhomogeneity of ejecta, offering unique insight into the nucleosynthesis in supernova explosions. Here we present detailed imaging and ...
