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., 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, 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 a dusty debris disk around an M star, the most common in the galaxypdf
