WASP-43b’s Bright Side Pointed Toward a Hot Interior
Five TESS sectors showed a 44-degree eastward phase offset and little evidence for reflective dayside clouds.
Summary
Five TESS sectors showed a 44-degree eastward phase offset and little evidence for reflective dayside clouds.
The team measured a 130 ± 34 parts-per-million eclipse depth and an eastward brightness offset of 44 ± 18 degrees. Compared with longer-wavelength JWST results, the TESS phase curve supports a cloud-poor dayside and a hot deep atmosphere.
Why it matters
Five TESS sectors showed a 44-degree eastward phase offset and little evidence for reflective dayside clouds.
Limits and context
No additional limitation was separately recorded.
Key claims
Five TESS sectors showed a 44-degree eastward phase offset and little evidence for reflective dayside clouds.
