The mention of planet's "installation," in the abstract and repeatedly throughout the article, I have found very confusing. The reference to Kopparapu et al. (2013) has no mention of the term whatsoever. I have found a mention of "instellation" from one of the authors working with Kopparapu [1]. Instellation, indeed, is, according to Wiki, "a generalization of insolation to stars other than the sun," which makes sense in this context.
I wonder if I am missing anything - given it's in MNRAS already - or this is likely an artifact of auto-correction.
