Kay Justtanont

Docent vid Astronomi och plasmafysik

Kays forskning fokuseras kring att studera rymddamm och gas runt sent utvecklade stjärnor, så kallade AGB-stjärnor. Mycket av Kays arbete involverar modellerande av markbaserade observationer samt data från olika astronomiska rymduppdrag. Kay är också intresserad av rymddamm i stjärnbildande regioner och utflöde från unga stellära objekt.

Kay arbetar för tillfället med det mid-infraröda instrumentet (MIRI) som svensk projekassistent. MIRI är ett av fyra instrument som ska flyga med James Webb Space Telescope (JWST) när det skjuts upp i rymden år 2018.
