If a planet has an atmosphere, it might also have clouds that reflect incoming starlight and cool the dayside. So if a planet's dayside is cooler than the maximum possible, it likely has an atmosphere. The subject of the study, HD 3167 b, is noticeably cooler than its expected maximum, providing strong evidence that it has an atmosphere.
