Large Starspot Groups on HAT-P-11 in Activity Cycle 1
Brett M. Morris, Suzanne L. Hawley, Leslie Hebb
HAT-P-11 is a planet-hosting K4V star in the Kepler field, with an activity cycle that bear similarities to the Sun's. The chromospheric activity of HAT-P-11 indicates that a new a…
Photometric Analysis and Transit Times of TRAPPIST-1 b and c
Brett M. Morris, Eric Agol, Suzanne L. Hawley
TRAPPIST-1 hosts seven Earth-sized planets transiting an M8 star. We observed mid-transit times of each of the inner two planets with the Astrophysical Research Consortium (ARC) 3.…
Towards Space-like Photometric Precision from the Ground with Beam-Shaping Diffusers
Gudmundur Stefansson, Suvrath Mahadevan, Leslie Hebb +21
We demonstrate a path to hitherto unachievable differential photometric precisions from the ground, both in the optical and near-infrared (NIR), using custom-fabricated beam-shapin…
Chromospheric Activity of HAT-P-11: an Unusually Active Planet-Hosting K Star
Brett M. Morris, Suzanne L. Hawley, Leslie Hebb +6
Kepler photometry of the hot Neptune host star HAT-P-11 suggests that its spot latitude distribution is comparable to the Sun's near solar maximum. We search for evidence of an act…
The Starspots of HAT-P-11: Evidence for a Solar-like Dynamo
Brett M. Morris, Leslie Hebb, James R. A. Davenport +2
We measure the starspot radii and latitude distribution on the K4 dwarf HAT-P-11 from Kepler short-cadence photometry. We take advantage of starspot occultations by its highly-misa…
H-ATLAS: A Candidate High Redshift Cluster/Protocluster of Star-Forming Galaxies
D. L. Clements, F. Braglia, G. Petitpas +31
We investigate the region around the Planck-detected z=3.26 gravitationally lensed galaxy HATLAS J114637.9-001132 (hereinafter HATLAS12-00) using both archival Herschel data from t…
