An international team led by scientists at Johns Hopkins University and the University of California at Davis used the EXES high-resolution mid-infrared spectrometer onboard SOFIA to determine the amount and location of water molecules around protostar AFGL 2591. AFGL 2591 is object number 2591 in a catalog of strong infrared sources discovered by a series of small infrared telescopes launched in rockets during the 1960s by the Air Force Geophysical Laboratory.
The first observations of an extrasolar planet by NASA’s SOFIA (Stratospheric Observatory for Infrared Astronomy) are reported in a paper published online on July 8 in the Journal of Astronomical Telescopes, Instruments, and Systems (JATIS) by Daniel Angerhausen (NASA Goddard Space Flight Center and Rensselaer Polytechnic Institute) and collaborators.
SOFIA measurements of ionized carbon and nitrogen gas at the edge of the Central Molecular Zone (CMZ) of the Milky Way were made with the GREAT far-IR heterodyne spectrometer (P.I. Rolf Güsten, MPIfR) as a part of SOFIA’s Guest Investigator program. The observations were made over the course of several nights in July 2013 during SOFIA’s first Southern Hemisphere deployment.
The CMZ is a 400 pc x 80 pc region around the galactic center containing 10 million solar masses of giant molecular clouds, many regions of active star formation, and frequent supernova explosions.
