3/3 The Hirano+2011 RM model has been integrated into EXOFASTv2. You can access it here (github.com/wangxianyu7/...). It will be merged into the main branch soon!

2/3 Additionally, we found that high planet-star mass-ratio systems generally tend to be aligned, even for hot stars. XO-3 is the sole exception, where its misalignment may have been triggered by a stellar companion. The upcoming Gaia epoch data can test this hypothesis.

1/3 We presented new Rossiter-McLaughlin effect measurements for the massive planet/brown dwarf XO-3 (Mp ~ 13 MJ) using NEID spectra. We confirmed that it remains misaligned (~41 degrees) with no evidence of temporal variation.

Working on it! Hopefully, we can have it before Christmas.
