While the number of detected exoplanets is still low, is there a model that, considering the number and duration of made observations, and the fact that (non)detections depend on orbital plane alignment and timing, can answer questions like

  • what is the typical number of exoplanets for a star?

  • what percentage of extrasolar systems can be expected to have at least one exoplanet?

  • how many (Jupiter, Earth)-like planets do we expect in each solar system?

  • which types of stars tend to have which types of planets?

    $\begingroup$ Can you clarify what your looking for ? Is it more statistics on detected exoplanets to date, for which NASA Exoplanet Archive is the best bet or a model of exoplanet formation and numbers per star etc or a model for how many exoplanet detections there should be ? $\endgroup$

    $\begingroup$ You seem to be looking for keywords like "completeness correction" and "detection bias correction". Try searching for those. $\endgroup$

    $\begingroup$ @astrosnapper Good question and link - I'm looking for a model of exoplanet formation and numbers per star that takes existing (non)detections and their probabilities into account $\endgroup$

    $\begingroup$ @AtmosphericPrisonEscape These are excellent terms! A model that would employ these is what I'm looking for $\endgroup$

  • $\begingroup$ Model and statistics are different things. This question is at least on the border of too broad imho. You are asking for a review paper on explanation research and observations $\endgroup$
