Episodic infall towards a compact disk in B335?
Per Bjerkeli, Jon P. Ramsey, Daniel Harsono +7
Previous observations of B335 have presented evidence of ongoing infall in various molecular lines, e.g., HCO, HCN, CO. There have been no confirmed observations of a rotationa…
Disk Wind Feedback from High-mass Protostars. II. The Evolutionary Sequence
Jan E. Staff, Kei E. I. Tanaka, Jon P. Ramsey +2
Star formation is ubiquitously associated with the ejection of accretion-powered outflows that carve bipolar cavities through the infalling envelope. This feedback is expected to b…
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…
The challenges of modelling microphysics: ambipolar diffusion, chemistry, and cosmic rays in MHD shocks
T. Grassi, M. Padovani, J. P. Ramsey +4
From molecular clouds to protoplanetary disks, non-ideal magnetic effects are important in many astrophysical environments. Indeed, in star and disk formation processes, it has bec…
