A comprehensive comparison of the Sun to other stars: searching for self-selection effects
Jose A. Robles, Charles H. Lineweaver, Daniel Grether +5
If the origin of life and the evolution of observers on a planet is favoured by atypical properties of a planet's host star, we would expect our Sun to be atypical with respect to…
The Metallicity of Stars with Close Companions
Daniel Grether, Charles H. Lineweaver
We examine the relationship between the frequency of close companions (stellar and planetary companions with orbital periods < 5 years) and the metallicity of their Sun-like (~ FGK…
How Dry is the Brown Dwarf Desert?: Quantifying the Relative Number of Planets, Brown Dwarfs and Stellar Companions around Nearby Sun-like Stars
Daniel Grether, Charles H. Lineweaver
Sun-like stars have stellar, brown dwarf and planetary companions. To help constrain their formation and migration scenarios, we analyse the close companions (orbital period < 5 ye…
What Fraction of Sun-like Stars have Planets?
Charles H. Lineweaver, Daniel Grether
The radial velocities of ~1800 nearby Sun-like stars are currently being monitored by eight high-sensitivity Doppler exoplanet surveys. Approximately 90 of these stars have been fo…
How common are Earths? How common are Jupiters?
Charles H. Lineweaver, Daniel Grether, Marton Hidas
Among the billions of planetary systems that fill the Universe, we would like to know how ours fits in. Exoplanet data can already be used to address the question: How common are J…
What can exoplanets tell us about our Solar System?
Charles H. Lineweaver, Daniel Grether, Marton Hidas
We update our analysis of recent exoplanet data that gives us a partial answer to the question: How does our Solar System compare to the other planetary systems in the Universe? Ex…
