A new L-dwarf member of the moderately metal-poor triple system HD 221356
B. Gauza, V. J. S. Béjar, R. Rebolo +10
We report on the discovery of a fourth component in the HD 221356 star system, previously known to be formed by an F8V, slightly metal-poor primary ([Fe/H]=-0.26), and a distant M8…
Dwarf spheroidal satellites of the Milky Way from dark matter free tidal dwarf galaxy progenitors: maps of orbits
R. A. Casas, V. Arias, K. Pena Ramírez +1
The long term time evolution of tidal dwarf satellite galaxies with two different initial densities orbiting a host galaxy that resembles the Milky Way has been studied using a lar…
New isolated planetary mass objects and the stellar and substellar mass function of the sigma Orionis cluster
K. Peña Ramírez, V. J. S. Béjar, M. R. Zapatero Osorio +2
We report on our analysis of the VISTA Orion ZYJHKs photometric data (completeness magnitudes Z=22.6 and J=21.0mag) focusing on a circular area of 2798.4 arcmin^2 around the young…
