    • A Super-solar metallicity for the progenitor of Kepler's supernova 

      Park, Sangwook; Badenes Montoliu, Carles; Mori, Koji; Kaida, Ryohei; Bravo Guil, Eduardo; Schenck, Andrew; Eriksen, Kristoffer A.; Hughes, John P.; Slane, Patrick O.; Burrows, David N.; Lee, Jae-Joon (2013-04)
      Article
      Open Access
      We have performed deep X-ray observations of the remnant of Kepler's supernova (SN 1604) as a Key Project of the Suzaku Observatory. Our main goal is to detect secondary Fe-peak elements in the supernova (SN) ejecta to ...
    • Chandrasekhar and sub-Chandrasekhar models for the x-ray emission of type Ia Supernova remnants. I. Bulk properties 

      Martinez Rodriguez, Hector; Badenes Montoliu, Carles; Lee, Shiu-Hang; Patnaude, Daniel J.; Foster, Adam; Yamaguchi, Hiroya; Auchettl, Katie; Bravo Guil, Eduardo; Slane, Patrick O.; Piro, Anthony; Park, Sangwook; Nagataki, Shigehiro (Institute of Physics (IOP), 2018-10-03)
      Article
      Open Access
      Type Ia supernovae originate from the explosion of carbon–oxygen white dwarfs in binary systems, but the exact nature of their progenitors remains elusive. The bulk properties of Type Ia supernova remnants, such as the ...
    • 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 ...
