SAC Seminar - Tim White: Kepler/K2 photometry of very bright stars

Info about event


Thursday 15 October 2015,  at 15:15 - 16:00



The K2 Mission is providing golden opportunities to study scientifically interesting targets in the ecliptic. Many of the most exciting targets are also the brightest, but the cost in pixels, coupled with the limited download bandwidth, means these targets may go unobserved. To overcome this we have developed methods to perform photometry in the wings of the PSF of bright stars, allowing them to be observed inexpensively. Additionally, engineering data acquired for photometric calibration can be used to reconstruct light curves for bright targets, including for stars observed by Kepler that were not specifically targeted. I will present results from applying these methods, particularly to the brightest stars in the Pleiades and Hyades clusters. The successful demonstration of these methods opens up the opportunity to study the brightest stars in future K2 Campaigns.
