Multiple planetary systems: Properties of the current sample
(Elsevier Science, 2017-08)
We carry out analyses on stellar and planetary properties of multiple exoplanetary systems in the currently available sample. With regards to the stars, we study their temperature, distance from the Sun, and metallicity ...
Dynamic portrait of the planetary 2/1 mean-motion resonance - I. Systems with a more massive outer planet
(WILEY-BLACKWELL, 2008)
We analyse the global structure of the phase space of the planar planetary 2/1 mean-motion resonance in cases where the outer planet is more massive than its inner companion. Inside the resonant domain, we show the existence ...
Searching for faint comoving companions to the alpha Centauri system in the VVV survey infrared images
(Oxford university press, 2017)
The VVV survey has observed the southern disc of the Milky Way in the near-infrared, covering 240 deg(2) in the ZYJHKs filters. We search the VVV survey images in a similar to 19 deg(2) field around alpha Centauri, the ...
GJ 273: on the formation, dynamical evolution, and habitability of a planetary system hosted by an M dwarf at 3.75 parsec
(EDP Science, 2020)
Context. Planets orbiting low-mass stars such as M dwarfs are now considered a cornerstone in the search for planets with the potential to harbour life. GJ 273 is a planetary system orbiting an M dwarf only 3.75 pc away, ...
Dynamics of the 3:1 resonant planetary systems
(American Astronomical UnionParaty, 2013)
Many of the discovered exoplanetary systems are involved inside mean-motion resonances. In this work we focus on the dynamics of the 3:1 mean-motion resonant planetary systems. Our main purpose is to understand the dynamics ...
When nature tries to trick us: An eclipsing eccentric close binary superposed on the central star of the planetary nebula M 3-2
(EDP Sciences, 2018-11)
Bipolar planetary nebulae (PNe) are thought to result from binary star interactions and, indeed, tens of binary central stars of PNe have been found, in particular using photometric time-series that allow for the detection ...
