Dynamical evolution and spectral characteristics of the stellar group Mamajek 2
E. Jilinski, V. G. Ortega, R. de la Reza +2
The dynamical evolution of the recently detected stellar group Mamajek 2 is studied by means of its past 3D orbit. The past orbits of the open clusters NGC 2516 and Persei, bel…
On the common origin of the AB Dor moving group and the Pleiades cluster
V. G. Ortega, E. Jilinski, R. de la Reza +1
AB Dor is the nearest identified moving group. As with other such groups, the age is important for understanding of several key questions. It is important, for example, in establis…
Dynamical Evolution of the TW Hya Association
R. de la Reza, E. Jilinski, V. G. Ortega
Using Galactic dynamics we have determined the age of the low mass post-T Tauri stars TW Hya Association (TWA). To do so we applied the method of Ortega et al.(2002, 2004) to five…
The optical/IR counterpart of the 3 July 1998 gamma-ray burst and its evolution
A. J. Castro-Tirado, M. R. Zapatero-Osorio, J. Gorosabel +21
We imaged the X-ray error box of GRB 980703, beginning 22.5 hours after the gamma--ray event, in both the optical R and near-infrared H bands. A fading optical/IR object was detect…
