A study of the stability regions in the planetary system HD 74156 - Can it host earthlike planets in habitable zones?
R. Dvorak, E. Pilat-Lohinger, B. Funk +1
Using numerical methods we thoroughly investigate the dynamical stability in the region between the two planets found in HD 74156. The two planets with minimum masses 1.56 M_JUP (H…

Planets in habitable zones: A study of the binary Gamma Cephei
R. Dvorak, E. Pilat-Lohinger, B. Funk +1
The recently discovered planetary system in the binary GamCep was studied concerning its dynamical evolution. We confirm that the orbital parameters found by the observers are in a…

Euler, Hipparcos and the five dwarfs : Reconstructing star formation histories in the Local Group
David Valls-Gabaud, Xavier Hernandez, Gerry Gilmore
The unprecedented quality of recent colour-magnitude diagrams of resolved stellar populations in nearby galaxies requires state-of-the-art techniques to infer the star formation hi…
