Radial Distribution of Planets Predictions based on the Core Accretion Gas Capture Planet formation Model
We investigate the problem of distribution of masses and orbital radii of planets resulting from the gas accretion gas capture model. First we follow the evolution of gas and solids from the moment when all solids are in the form of small grains to the stage when most of them are in the form of planetesimals for a set of different initial masses and sizes of protoplanetary disks. Based on that ...
متن کاملRadial distribution of dose.
The radial distribution of dose about the path of a heavy ion, principally from delta rays, is one of the central contributions of atomic physics to the systematization of high LET radiation effects in condensed matter, whether the detection arises in chemical, physical, or biological systems. In addition to the radial distribution of dose, we require knowledge of the response of the system to ...
متن کاملExoFit : orbital parameters of extra-solar planets from radial velocities
Retrieval of orbital parameters of extrasolar planets poses considerable statistical challenges. Due to sparse sampling, measurement errors, parameters degeneracy and modelling limitations there are no unique values of basic parameters such as period and eccentricity. Here we estimate the orbital parameters from radial velocity data in a Bayesian framework by utilising Markov Chain Monte Carlo ...
متن کاملDetectability of Extrasolar Planets in Radial Velocity Surveys
Radial velocity surveys are beginning to reach the time baselines required to detect Jupiter analogs, as well as sub-Saturn mass planets in close orbits. Therefore it is important to understand the sensitivity of these surveys at long periods and low amplitudes. In this paper, I derive analytic expressions for the detectability of planets at both short and long periods, for circular and eccentr...
متن کاملPlanets of young stars : the TLS radial velocity survey
We report on the search for planets orbiting 46 nearby young stars performed at the State Observatory of Turingia (TLS) by means of a radial velocity survey. The aim of this program is to test the theories of formation/evolution of planetary systems. For 19(8) stars we can exclude planets with M sin i ≥ 1 M J (5 M J) and P ≤ 10 days; we find 1 short period binary and 5 stars with long period RV...
