The Kepler Dichotomy in Planetary Disks: Linking Kepler Observables to Simulations of Late-Stage Planet Formation
John Moriarty, Sarah Ballard
NASA's Kepler Mission uncovered a wealth of planetary systems, many with planets on short-period orbits. These short-period systems reside around 50% of Sun-like stars and are simi…
Building massive compact planetesimal disks from the accretion of pebbles
John Moriarty, Debra Fischer
We present a model in which planetesimal disks are built from the combination of planetesimal formation and accretion of radially drifting pebbles onto existing planetesimals. In t…
Fiber scrambling for high-resolution spectrographs. II. A double fiber scrambler for Keck Observatory
Julien F. P. Spronck, Debra A. Fischer, Zachary Kaplan +4
We have designed a fiber scrambler as a prototype for the Keck HIRES spectrograph, using double scrambling to stabilize illumination of the spectrometer and a pupil slicer to incre…
Chemistry in an Evolving Protoplanetary Disk: Effects on Terrestrial Planet Composition
John Moriarty, Nikku Madhusudhan, Debra Fischer
The composition of planets is largely determined by the chemical and dynamical evolution of the disk during planetesimal formation and growth. To predict the diversity of exoplanet…
Planet Hunters. VI: An Independent Characterization of KOI-351 and Several Long Period Planet Candidates from the Kepler Archival Data
Joseph R. Schmitt, Ji Wang, Debra A. Fischer +29
We report the discovery of 14 new transiting planet candidates in the Kepler field from the Planet Hunters citizen science program. None of these candidates overlapped with Kepler…
M2K: II. A Triple-Planet System Orbiting HIP 57274
Debra A. Fischer, Eric Gaidos, Andrew Howard +14
Doppler observations from Keck Observatory have revealed a triple planet system orbiting the nearby mid-type K dwarf, HIP 57274. The inner planet, HIP 57274b, is a super-Earth with…
