A Search for Transiting Planets in the Globular Cluster M4 with K2: Candidates and Occurrence Limits
Joshua J. Wallace, Joel D. Hartman, Gaspar A. Bakos
We perform a search for transiting planets in the NASA K2 observations of the globular cluster (GC) M4. This search is sensitive to larger orbital periods ( days, com…
A Search for Variable Stars in the Globular Cluster M4 with K2
Joshua J. Wallace, Joel D. Hartman, Gaspar A. Bakos +1
We extract light curves for 4554 objects with in the K2 superstamp observations of the globular cluster M4, including 3784 cluster members, and search for variability. Amo…
Ultralow-amplitude RR Lyrae Stars in M4
Joshua J. Wallace, Joel D. Hartman, Gaspar A. Bakos +1
We report evidence for a new class of variable star, which we dub millimagnitude RR Lyrae (mmRR). From K2 observations of the globular cluster M4, we find that out of 24 horizontal…
