The Little Dippers: Transits of Star-grazing Exocomets?

Megan Ansdell, Eric Gaidos, Tom L. Jacobs +9

We describe EPIC 205718330 and EPIC 235240266, two systems identified in the K2 data whose light curves contain episodic drops in brightness with shapes and durations similar to th…

Scientific Domain Knowledge Improves Exoplanet Transit Classification with Deep Learning

Megan Ansdell, Yani Ioannou, Hugh P. Osborn +5

Space-based missions such as Kepler, and soon TESS, provide large datasets that must be analyzed efficiently and systematically. Recent work by Shallue & Vanderburg (2018) successf…

GPI spectra of HR 8799 c, d, and e from 1.5 to 2.4m with KLIP Forward Modeling

Alexandra Z. Greenbaum, Laurent Pueyo, Jean-Baptiste Ruffio +51

We explore KLIP forward modeling spectral extraction on Gemini Planet Imager coronagraphic data of HR 8799, using PyKLIP and show algorithm stability with varying KLIP parameters.…
