**Still possible** Answers **1** questionPublished0

## Where it stands

**Still possible** Its tests haven't settled it: one piece of evidence for, one against. It needs two reviews to be accepted.

## What it predicts

- Out-of-dip variability and infrared excess from star B.

## What would rule it out

- Resolved photometry showing star B steady while the dips continue.

## Evidence 1 for · 1 against

[Star B's possible infrared excess would be hidden by the dilution.](https://mysteriesdept.com/mysteries/hd-139139-random-transiter/evidence/EVD0D79S5842FX3/star-bs-possible-infrared-excess-would-be-hidden-by-the)
