Dynamics of the 3/1 planetary mean-motion resonance. An application to the HD60532 b-c planetary system
A. J. Alves, T. A. Michtchenko, M. Tadeu dos Santos
In this paper, we use a semi-analytical approach to analyze the global structure of the phase space of the planar planetary 3/1 mean-motion resonance, in cases where the outer plan…
Transiting exoplanets from the CoRoT space mission XXVIII. CoRoT-33b, an object in the brown dwarf desert with 2:3 commensurability with its host star
Sz. Csizmadia, A. Hatzes, D. Gandolfi +32
We report the detection of a rare transiting brown dwarf with a mass of 59 M_Jup and radius of 1.1 R_Jup around the metal-rich, [Fe/H] = +0.44, G9V star CoRoT-33. The orbit is ecce…
Formation and evolution of the two 4/3 resonant giants planets in HD 200946
M. Tadeu dos Santos, J. A. Correa-Otto, T. A. Michtchenko +1
It has been suggested that HD 200964 is the first exoplanetary system with two Jovian planets evolving in the 4/3 mean- motion resonance. Previous scenarios to simulate the formati…
Transiting exoplanets from the CoRoT space mission: XXVI. CoRoT-24: A transiting multi-planet system
R. Alonso, C. Moutou, M. Endl +48
We present the discovery of a candidate multiply-transiting system, the first one found in the CoRoT mission. Two transit-like features with periods of 5.11 and 11.76d are detected…
A new analysis of the GJ581 extrasolar planetary system
M. Tadeu dos Santos, G. G. Silva, S. Ferraz-Mello +1
We have done a new analysis of the available observations for the GJ581 exoplanetary system. Today this system is controversial due to choices that can be done in the orbital deter…
On planetary mass determination in the case of super-Earths orbiting active stars. The case of the CoRoT-7 system
S. Ferraz-Mello, M. Tadeu dos Santos, C. Beauge +2
This investigation uses the excellent HARPS radial velocity measurements of CoRoT-7 to re-determine the planet masses and to explore techniques able to determine mass and elements…
