On the stellar content of the open clusters Melotte 105, Hogg 15, pismis 21 and Ruprecht 140 [PDF]

open access: yes, 2001
CCD observations in the B, V and I passbands have been used to generate colour-magnitude diagrams reaching down to V = 19 mag for two slightly characterized (Melotte 105 and Hogg 15) and two almost unstudied (Pismis 21 and Ruprecht 140) open clusters ...

A new method to find the potential center of N-body systems [PDF]

open access: yes, 2002
We present a new and fast method to nd the potential center of an N-body distribution. The method uses an iterative algorithm which exploits the fact that the gradient of the potential is null at its center: it uses a smoothing radius to avoid getting
