Long period exoplanets from dynamical relaxation
Recent imaging campaigns indicate the likely existence of massive planets (∼ 1− 10 MJ ) on ∼> 1000 year orbits about a few percent of stars. Such objects are not easily explained in most current planet formation models. In this Letter we use ensembles of 100 N-body simulations to evaluate the potential for planet scattering during relaxation of dynamically active systems to explain the populati...
متن کاملLong Period Exoplanets
Recent imaging campaigns indicate the possible existence of massive planets on ∼> 1000 year orbits about a few percent of normal stars. Such objects are not easily explained in most current planet formation models. In this Letter we use a large ensemble of N-body simulations to evaluate the potential for planet scattering during relaxation of dynamically active systems to explain very long peri...
متن کاملThermal Tides in Short Period Exoplanets
Time-dependent insolation in a planetary atmosphere induces a mass quadrupole upon which the stellar tidal acceleration can exert a force. This “thermal tide” force can give rise to secular torques on the planet and orbit as well as radial forces causing eccentricity evolution. We apply this idea to the close-in gas giant exoplanets (“hot Jupiters”). The response of radiative atmospheres is com...
متن کاملRadio Emission from Exoplanets
We present results from new low frequency observations of two extrasolar planetary systems (ε Eridani and HD128311) taken at 150 MHz with the Giant Metrewave Radio Telescope (GMRT). We do not detect either system, but are able to place tight upper limits on their low frequency radio emission.
متن کاملOrbital migration and the period distribution of exoplanets
An abstract should be given e use the model for the migration of planets introduced in Del Popolo, Yesilyurt & Ercan (2003) to calculate the observed mass and semimajor axis distribution of extra-solar planets. The assumption that the surface density in planetesimals is proportional to that of gas is relaxed, and in order to describe disc evolution we use a method which, using a series of simpl...
