Atomic Shocks in the Outflow of L1551 IRS 5 Identified with SOFIA-upGREAT Observations of [OI]

Yao-Lun Yang, Neal J. Evans, Agata Karska +5

We present velocity resolved SOFIA/upGREAT observations of [OI] and [CII] lines toward a Class I protostar, L1551 IRS 5, and its outflows. The SOFIA observations detect [OI] emissi…

Detection of a dense SiO jet in the evolved protostellar phase

Somnath Dutta, Chin-Fei Lee, Doug Johnstone +25

Jets and outflows trace the accretion history of protostars. High-velocity molecular jets have been observed from several protostars in the early Class\,0 phase of star formation,…

Star Formation Histories of Ultra-Faint Dwarf Galaxies: environmental differences between Magellanic and non-Magellanic satellites?

Elena Sacchi, Hannah Richstein, Nitya Kallivayalil +18

We present the color-magnitude diagrams and star formation histories (SFHs) of seven ultra-faint dwarf galaxies: Horologium 1, Hydra 2, Phoenix 2, Reticulum 2, Sagittarius 2, Trian…

A Low-mass Cold and Quiescent Core Population in a Massive Star Protocluster

Shanghuo Li, Xing Lu, Qizhou Zhang +24

Pre-stellar cores represent the initial conditions of star formation. Although these initial conditions in nearby low-mass star-forming regions have been investigated in detail, su…
