Good talk today from Karen Collins, a graduate student in U of Louisville’s Physics program.
She spoke about her work in ground-based observations of exoplanet transits, which are impressively simple but amazingly powerful for revealing new planets and telling us about already known planets.
Collins helped discover and confirm the Saturn-sized planet KELT-6 b (pictured at right), in a roughly 8 day orbit around a metal-poor F-type star.
This is a particularly interesting discovery because gas giant planets seem to prefer forming around metal-RICH stars, where there was more material to form planets. But KELT-6 b seems to buck that trend, and this result may point to something unusual about the planet’s formation and history.
