Claims

C1strongest claim

We derived effective temperatures, surface gravities, projected rotational velocities, microturbulent velocities, overall metallicities, iron abundances, stellar masses, and radii for our sample of 18 hot stars. Building on our previous work on FGK host stars, we show that correlations between stellar mass, metallicity, and planetary radii also extend to early-type stars.

C2weakest assumption

The iterative spectro-trigonometric approach optimised for high-temperature stars produces accurate parameters when model atmospheres and evolutionary tracks are combined with photometry-based radii.

C3one line summary

Uniform spectro-trigonometric parameters for 18 hot Ariel candidate stars show that mass-metallicity-planetary radius correlations extend to early-type hosts.
