## What it's used for here

arXiv:2607.20643 (July 2026). Models the symmetric 1.1 per cent dip in TESS Sector 15 (September 2019) as a planetary transit and combines it with archival and new radial velocities: a 2.3-sigma companion of about 9 Jupiter masses and 1.7 Jupiter radii with a period of at least about 1030 days, in several allowed period windows. Independently recovered in this department's TESS search.
