Description

To better understand how planets form, it is important to study planet occurrence rates as a function of stellar mass. However, estimating masses of field stars is often difficult. Over the past decade, a controversy has arisen about the inferred occurrence rate of gas-giant planets around evolved intermediate-mass stars – the so-called ‘retired A-stars’. The high masses of these red-giant planet hosts, derived using spectroscopic information and stellar evolution models, have been called into...[Show more]
