EXES observations of Betelgeuse during the 2020 V-Band minimum are available through the SOFIA archive. These observations were focused on high-spectral resolution spectra around 25 µm, encompassing forbidden [Fe II], [S I] and two water absorption features to investigate potential changes in the photospheric kinematics during the dimming event.
The recent Type Ia Supernova in nearby galaxy M82, SN2014J, was observed by FORCAST and FLITECAM. The FORCAST data consists of imaging at 7.7, 8.6, 11.1, 19.7, 37.1 µm as well as spectroscopy of 4.0-8.6 µm and 8.4-13.7 µm. Additional FLITECAM grism spectroscopy are available in the J,H,K, and L+M B and C bands. These data help to constrain Type Ia Supernova properties for cosmological models.
Supernovae send copious amount of energy into the interstellar medium (ISM) and are an important driver of its chemical evolution. IC 443, at a distance of 1.5 kpc, is one of the best studied supernova remnants (SNR) interacting with a molecular cloud. It is thus an excellent target to investigate the physics and chemistry of shock models. The SOFIA telescope covers and can spectrally resolve a variety of molecular lines that trace shocks. Several of these lines have been observed towards IC 443 with different projects. Combined, they allow an in-depth study of the shocks that interact with the molecular cloud.
