    • Many-body forces in the equations of state of hyperonic matter 

      Gomes, Rosana de Oliveira; Dexheimer, Veronica Antocheviz; Schramm, Stefan; Vasconcellos, Cesar Augusto Zen (2015) [Artigo de periódico]
      In this work we introduce an extended version of the formalism proposed originally by Taurines et al. that considers the effects of many-body forces simulated by nonlinear self-couplings and meson–meson interaction ...

    • Very low mass stellar and substellar companions to solar-like stars from MARVELS. II. A short-period companios orbiting an F star with evidence of a stellar tertiary and significant mutual inclination

      We report the discovery via radial velocity (RV) measurements of a short-period (P = 2.430420±0.000006 days) companion to the F-type main-sequence star TYC 2930-00872-1. A long-term trend in the RV data also suggests the ...

Shelden; Wan, Xiaoke; Wang, Ji; Zhao, Bo (2013) [Artigo de periódico]
      We describe the discovery of a likely brown dwarf (BD) companion with a minimum mass of 31.7 ± 2.0 MJup to GSC 03546-01452 from the MARVELS radial velocity survey, which we designate as MARVELS-6b. For reasonable priors, ...
