Measurement of Spin-Orbit Misalignment and Nodal Precession for the Planet around Pre-Main-Sequence Star PTFO 8-8695 From Gravity Darkening

Autor: Barnes, Jason W., van Eyken, Julian C., Jackson, Brian K., Ciardi, David R., Fortney, Jonathan J.

PTFO 8-8695b represents the first transiting exoplanet candidate orbiting a pre-main-sequence star. We find that the unusual lightcurve shapes of PTFO 8-8695 can be explained by transits of a planet across an oblate, gravity-darkened stellar disk. We

A Search for Exozodiacal Clouds with Kepler

Autor: Stark, Christopher C., Boss, Alan P., Weinberger, Alycia J., Jackson, Brian K., Endl, Michael, Cochran, William D., Johnson, Marshall, Caldwell, Caroline, Agol, Eric, Ford, Eric B., Hall, Jennifer R., Ibrahim, Khadeejah A., Li, Jie

Planets embedded within dust disks may drive the formation of large scale clumpy dust structures by trapping dust into resonant orbits. Detection and subsequent modeling of the dust structures would help constrain the mass and orbit of the planet and

The EVIL-MC Model for Ellipsoidal Variations of Planet-Hosting Stars and Applications to the HAT-P-7 System

Autor: Jackson, Brian K., Lewis, Nikole K., Barnes, Jason W., Deming, L. Drake, Showman, Adam P., Fortney, Jonathan J.

We present a new model for Ellipsoidal Variations Induced by a Low-Mass Companion, the EVIL-MC model. We employ several approximations appropriate for planetary systems to substantially increase the computational efficiency of our model relative to m

Extrasolar Planet Transits Observed at Kitt Peak National Observatory

Autor: Sada, Pedro V., Deming, Drake, Jennings, Donald E., Jackson, Brian K., Hamilton, Catrina M., Fraine, Jonathan, Peterson, Steven W., Haase, Flynn, Bays, Kevin, Lunsford, Allen, O'Gorman, Eamon

We obtained J-, H- and JH-band photometry of known extrasolar planet transiting systems at the 2.1-m Kitt Peak National Observatory Telescope using the FLAMINGOS infrared camera between October 2008 and October 2011. From the derived lightcurves we h
