Summary

A new metric combines expected tidal shape change with photometric signal-to-noise for JWST and Ariel phase curves.

The authors identify WASP-33 b, WASP-76 b and HAT-P-32 b as strong unmeasured targets. Simulations suggest one continuous JWST observation of WASP-76 b could constrain its fluid Love number to about 0.09 precision; that is a forecast, not a completed observation.

Why it matters

A new metric combines expected tidal shape change with photometric signal-to-noise for JWST and Ariel phase curves.

Limits and context

  • Simulations suggest one continuous JWST observation of WASP-76 b could constrain its fluid Love number to about 0.09 precision; that is a forecast, not a completed observation.

Key claims

  1. A new metric combines expected tidal shape change with photometric signal-to-noise for JWST and Ariel phase curves.

    Qualification: Simulations suggest one continuous JWST observation of WASP-76 b could constrain its fluid Love number to about 0.09 precision; that is a forecast, not a completed observation.
