Early F- and A-type stars, with masses above 1.4 solar masses, are underrepresented in planet host studies, yet they offer a unique probe of intermediate-mass star–planet connections. We present a homogeneous spectroscopic and photometric analysis of 18 such stars from the Ariel Mission Candidate Sample. Their radiative envelopes preserve surface chemical signatures that may trace accretion or planet formation history. We explore correlations between stellar mass, metallicity, and the presence of giant planets, providing insights into the formation and evolution of planetary systems around early-type stars.
