Young "Dipper" Stars in Upper Sco and Oph Observed by K2
M. Ansdell, E. Gaidos, S. A. Rappaport +8
We present ten young (10 Myr) late-K and M dwarf stars observed in K2 Campaign 2 that host protoplanetary disks and exhibit quasi-periodic or aperiodic dimming events. Th…
IR-excesses around nearby Lambda Boo stars are caused by debris disks rather than ISM bow waves
Zachary H Draper, Brenda C Matthews, Grant M Kennedy +3
Lambda Boo stars are predominately A-type stars with solar abundant C, N, O, and S, but up to 2 dex underabundances of refractory elements. The stars' unusual surface abundances co…
The AU Mic Debris Disk: far-infrared and submillimeter resolved imaging
Brenda C. Matthews, Grant Kennedy, Bruce Sibthorpe +20
We present far-infrared and submillimeter maps from the Herschel Space Observatory and the James Clerk Maxwell Telescope of the debris disk host star AU Microscopii. Disk emission…
Planet Hunters X. KIC 8462852 - Where's the Flux?
T. S. Boyajian, D. M. LaCourse, S. A. Rappaport +46
Over the duration of the Kepler mission, KIC8462852 was observed to undergo irregularly shaped, aperiodic dips in flux of up to \%. The dipping activity can last for betwe…
Kuiper belt structure around nearby super-Earth host stars
Grant M. Kennedy, Luca Matrà, Maxime Marmier +9
We present new observations of the Kuiper belt analogues around HD 38858 and HD 20794, hosts of super-Earth mass planets within 1 au. As two of the four nearby G-type stars (with H…
Warm exo-Zodi from cool exo-Kuiper belts: the significance of P-R drag and the inference of intervening planets
Grant M. Kennedy, Anjali Piette
Poynting-Robertson drag has been considered an ineffective mechanism for delivering dust to regions interior to the cool Kuiper belt analogues seen around other Sun-like stars. Thi…
Stellar Multiplicity and Debris Disks: An Unbiased Sample
David R. Rodriguez, Gaspard Duchene, Henry Tom +4
Circumstellar dust disks have been observed around many nearby stars. However, many stars are part of binary or multiple stellar systems. A natural question arises regarding the pr…
Does the presence of planets affect the frequency and properties of extrasolar Kuiper Belts? Results from the Herschel DEBRIS and DUNES surveys
A. Moro-Martin, J. P. Marshall, G. Kennedy +14
The study of the planet-debris disk connection can shed light on the formation and evolution of planetary systems, and may help predict the presence of planets around stars with ce…
Constraining the orbits of sub-stellar companions imaged over short orbital arcs
Tim D. Pearce, Mark C. Wyatt, Grant M. Kennedy
Imaging a star's companion at multiple epochs over a short orbital arc provides only four of the six coordinates required for a unique orbital solution. Probability distributions o…
Target Selection for the LBTI Exozodi Key Science Program
Alycia J. Weinberger, Geoff Bryden, Grant M. Kennedy +13
The Hunt for Observable Signatures of Terrestrial planetary Systems (HOSTS) on the Large Binocular Telescope Interferometer will survey nearby stars for faint emission arising from…
