BeskrivningExoplanet Period-Mass Scatter History.gif |
English: Scatter plot of mass, m, and semimajor axis, a, for exoplanet discoveries through 2014-09-23 animated by year, indicating the discovery method using distinct colors:
Estimates (see "important note" below) of m and a are indicated with circles. Scales indicate (log10 of) mass, m, expressed as Jupiter masses (left) and Earth masses (right); and (log10 of) semimajor axis, a, expressed in AU (bottom), and the corresponding period, p for a planet orbiting a Sun-mass star, expressed in Earth years. Reference lines are provided in the final frame as a rough measure of the difficulty of detecting exoplanets using radial velocity and transits. Dashed lines trace the combinations of m and a values that produce the indicated radial velocity semi-amplitude K for a planet orbiting a solar-mass star (assuming m << M). Dashed lines trace the m (for Jupiter-density) and a values where the geometric probability, P, of transit for a solar-radius star (assuming a circular orbit, so that e and ω can be ignored) is the indicated value (less than the indicated proportion of all planets to the right of a given line will have transiting orbits). Exoplanet data is from the Open Exoplanet Catalogue,[1] version 811d352, including some (mostly from the Kepler mission) whose semi major axes are computed from period data. The figure excludes 4 planets with semimajor axes outside the range of the figure and 1 (PSR B1257+12 b) with a mass lower than the range of the figure. Important note: This figure is intended to serve as a visualization of the catalog of generally accepted candidate exoplanets using the distribution of some of their basic properties related to detection. No attempt has been made to characterize the degree of confidence (which varies widely) in the existence of a given planet or its properties. Nor is any attempt made to convey systematic errors associated with a particular method. In particular, the indicated mass, m, for an exoplanet characterized using radial velocity is the minimum mass (so that the actual distrubiton of masses for non-transiting planets may be shifted and "smeared" significantly upward). Note: Due to limitations with MediaWiki's handling of GIFs, the previews and thumbnails for this file are of very poor quality and are not intended for use in articles.
