De Rosa, R. J. & Kalas, P.  2019, A near-coplanar stellar flyby of the planet host star HD 106906, Astronomical Journal, Vol. 157, 125.  Discovered two stars that had a close approach to HD 106906 which may explain the disrupted architecture of the planetary system. pdf

Kalas, P., Rajan, A., Wang, J.J. et al. 2015, Direct imaging of an asymmetric debris disk in the HD 106906 planetary system, Astrophysical Journal, Vol. 814, pg. 32 (12 pp) This is the first study to directly detect a disrupted dust disk with a misaligned exoplanet exterior to the disk.pdf

Kalas, P., Graham, J.R., Fitzgerald, M.P. & Clampin, M. 2013, STIS coronagraphic imaging of Fomalhaut:Main belt structure and the orbit of Fomalhaut b, Astrophysical Journal, Vol. 775, 31 pp. The orbital elements of Fomalhaut b were measured for the first time in this paper, finding a highly elliptical orbit. — pdf

Kalas, P., Graham, J.R., Chiang, E., Fitzgerald, M. P., Clampin, M. C., Kite, E. S., Stapelfeldt, K., Marois, C., & Krist, J. 2008, Optical images of an exosolar planet 25 light-years from Earth, Science, Vol. 322, pp. 1345 – 1348. This paper announces the first visible-light detection of an exoplanet directly observed to orbit a star.  It may also represent the first discovery of an exoplanetary ring system in reflected light. — pdf

Kalas, P., Duchene, G., Fitzgerald, M .& Graham, J.R. 2007, Discovery of an extended debris disk around the F2V star HD 15745Astrophysical Journal Letters, Vol. 671, pp. L161 – L164 —pdf

Kalas, P., Fitzgerald, M. and Graham, J.R. 2007, Discovery of extreme asymmetry in the debris disk in the debris disk surrounding HD 15115, 2007, Astrophysical Journal Letters, Vol 661, pp. L85 – L88 —pdf

Kalas, P., Graham, J.R., Clampin, M. C., and Fitzgerald, M. 2006, First scattered scattered light images of debris disks around HD 53143 and HD 139664, Astrophysical Journal, Vol. 635, pp. L57 – L60. —pdf

Kalas, P., Graham, J.R., and Clampin, M. 2005, A planetary system as the origin of structure in Fomalhaut’s dust belt, Nature, Vol. 435, pp. 1067-1070.  The first paper in astronomy to show a comet belt offset from symmetry around the star.  In The Oneironauts, this discovery is interpreted as scientific evidence for precognitive dreaming.pdf

Kalas, P., Liu, M. and Matthews, B. 2004, Discovery of a large dust disk around the nearby star AU Microscopii, Science, Vol. 303, pp. 1990-1992. This study provides the first direct image of a dusty debris disk around an M star, the most common type of star in the galaxypdf
