This artist’s impression depicts a dying Sun-like star engulfing an exoplanet. New research published in Monthly Notices of the Royal Astronomical Society suggests that ageing stars may be destroying the

Appropriateness of stacking two planets with identical chemical abundances (H2O and CO2 as the only active species) across surface gravity (𝑔) and equilibrium temperature (Teq). The reference planet is marked
