DESCRIPTION:Speakers: Paul Mollière (MPIA)\nHigh resolution spectroscopy 
 is quickly establishing itself as one of the most exciting ground-based ob
 servational techniques for exoplanets. Especially the doppler shifts of at
 omic and molecular lines are an excellent probe of dynamics and thus offer
  a unique window into the atmospheres of exoplanets. This information is h
 ighly complementary when compared to space-based telescopes\, which observ
 e at lower resolution. What is more\, velocity differences observed for di
 fferent absorbers are thought to probe their spatial distribution in the a
 tmosphere\, unlocking its 3-d nature. To interpret observations that probe
  the multi-d structure of atmospheres we are developing an open-source ext
 ension to our atmospheric retrieval package petitRADTRANS\, called pRT-Ora
 nge. pRT-Orange divides the atmosphere of the planet into (orange) segment
 s that share common properties such as temperature\, abundance\, or cloud 
 structure. The location\, extent and number of segments can be freely chos
 en\, allowing for simple or complex atmospheric parameterizations. Arbitra
 ry velocity fields can be specified for the Doppler shifts\, ranging from 
 planetary rotation to feeding in the dynamic solutions of general circulat
 ion models. At the moment pRT-Orange works for transmission only. In my ta
 lk I will present the current state of the code development\, and grant ea
 rly access to pRT-Orange at the meeting\, if people are interested (with t
 he obvious work-in-progress disclaimer).\n\nhttps://iaus379.aip.de/event/1
