Research

Can the composition of a planet tell us something about its formation history? I'm interested in the physical and chemical conditions and processes in planet-forming environments, and in how those relate to the properties of planets and planetary systems. Most of my current work deals with elemental abundances and volatiles in protoplanetary disks, employing powerful telescopes like ALMA and APEX, and physical-chemical disk models. I also do a bit of work on debris disks and molecular spectroscopic studies of star forming regions.

Selected papers

Volatile locking and release in protoplanetary disks (detailed modelling of molecular and atomic lines from TW Hya and HD 100546, confirming a factor 100 depletion of C and O in the TW Hya disk, and determining that C/O > 1; Kama et al. 2016b)

Observations and modelling of CO and [Ci] in protoplanetary disks (definitive detections of atomic carbon in disks and modelling which relates it to the level of carbon depletion; Kama et al. 2016a)

Fingerprints of giant planets in the photospheres of Herbig stars (young A-type stars hosting transitional disks have photospheres depleted of refractory elements -- matching the high gas-to-dust ratio in their dust-depleted gaps and cavities; Kama, Folsom & Pinilla 2015)

Inner rim structures of protoplanetary disks (numerical and analytical models of the dust sublimation region; Kama et al. 2009)
