Matthias Maercker

Forskare vid Chalmers, Rymd-, geo- och miljövetenskap, Astronomi och plasmafysik, Galaktisk astrofysik

Matthias Maerckers huvudsakliga forskningsintressen ligger i studerandet av utvecklade stjärnor på den asymptotiska jättegrenen (AGB) och deras massförlustegenskaper. Matthias använder observationsdata från t.ex. Herschel / HIFI, APEX, IRAM:s 30m-teleskop, och ALMA för att begränsa massförlustnivåer, massförlustgeometrin, och de kemiska egenskaperna hos de cirkumstellära höljena. Matthias är särskilt intresserad av förändringen i massförlustegenskaper under en termisk puls samt bildandet av fristående skal runt utvecklade stjärnor.
