Are Stars Really Ingesting Their Planets? Examining an Alternative Explanation by Nadine H. Soliman, Philip F. Hopkins

“…Our results show that the distribution of refractory abundance variations (Δ[X/H]) has extended tails, with about 10%–30% of all stars displaying variations around ∼0.1 dex. These variations are comparable to the accretion of 2–5 M _⊕ of planetary material into the convective zones of Sun-like stars. …”
