    • Dynamical studies of cluster pairs in the magellanic clouds 

      Oliveira, Marcio Ramos de; Dottori, Horacio Alberto; Bica, Eduardo Luiz Damiani (1998) [Artículo de periódico]
      We performed N-body simulations of star cluster encounters with Hernquist’s TREECODE in a CRAY YMP-2E computer under different initial conditions (relative positions and velocities, cluster sizes, masses and concentration ...

    • Potenciais gravitacionais de N-corpos 

      Fausti Neto, Angelo; Dottori, Horacio Alberto (1998) [Resumen publicado en evento]

    • Stability and self-organization of planetary systems 

      Pakter, Renato; Levin, Yan (2018) [Artículo de periódico]
      We show that stability of planetary systems is intimately connected with their internal order. An arbitrary initial distribution of planets is susceptible to catastrophic events in which planets either collide or are ejected ...

    • Very low mass stellar and substellar companions to solar-like stars from MARVELS. I. A low-mass ratio stellar companion to TYC 4110-01037-1 in a 79 day orbit

Shelden; Simmons, Audrey E.; Tofflemire, Benjamin M.; Wan, Xiaoke; Wang, Ji; Zhao, Bo (2012) [Artículo de periódico]
      TYC 4110-01037-1 has a low-mass stellar companion, whose small mass ratio and short orbital period are atypical among binary systems with solar-like (Teff 6000 K) primary stars. Our analysis of TYC 4110-01037-1 reveals it ...
