  • On the origin of the metallicity dependence in dynamically formed extragalactic low-mass X-ray binaries 

    Ivanova, Natalia; Fragos, Tassos; Kim, Dong-Woo; Fabbiano, Guiseppina; Avendano Nandez, Jose Luis; Lombardi, James C. Jr; Sivakoff, Gregory R.; Voss, Rasmus; Jordán, Andrés (Institute of Physics, 2012-12-01)
    Globular clusters (GCs) effectively produce dynamically formed low-mass X-ray binaries (LMXBs). Observers detect ~100 times more LMXBs per stellar mass in GCs compared to stars in the fields of galaxies. Observationally, ...
  • Stability and Coalescence of Massive Twin Binaries 

    Hwang, J.; Lombardi, James C. Jr; Rasio, F. A.; Kalogera, V. (The American Astronomical Society., 2015-06-12)
    Massive stars are usually found in binaries, and binaries with periods less than 10 days may have a preference for near equal component masses ("twins"). In this paper we investigate the evolution of massive twin binaries ...
  • Twin Binaries: Studies of Stability, Mass Transfer, and Coalescence 

    Lombardi, James C. Jr; Holtzman, William; Dooley, K. L.; Gearity, Kyle; Kalogera, V.; Rasio, F. A. (IOP, 2011-07-28)
    Motivated by suggestions that binaries with almost equal-mass components ("twins") play an important role in the formation of double neutron stars and may be rather abundant among binaries, we study the stability of ...
  • Twin Binaries: Studies of Stability, Mass Transfer, and Coalescence 

    Lombardi, James C. Jr; Holtzman, William; Dooley, Katherine L.; Gearity, Kyle; Kalogera, Vicky; Rasio, Frederic (Institute of Physics, 2011-08-20)
    Motivated by suggestions that binaries with almost equal-mass components (“twins”) play an important role in the formation of double neutron stars and may be rather abundant among binaries, we study the stability of ...
  • V1309 Sco: Understanding a merger 

    Nandez, J. L. A.; Ivanova, N.; Lombardi, James C. Jr (IOP, 2014-05-01)
    One of the two outcomes of a common envelope (CE) event is a merger of the two stars. To date, the best known case of a binary merger is the V1309 Sco outburst, where the orbital period was known and observed to decay up ...
