Economic potential for improving the nutritional characteristics of feed grains [PDF]

A comprehensive set of potential new feed grains for Australia was evaluated to help establish the options with the highest priorities for research. The cost-reducing impacts of the different options were analysed using a linear-programming model that ...

A JWST, ALMA, and VLA Survey of the Ophiuchus A Star-forming Region: Unveiling Hidden Dust Mass and Connecting Infrared Outflows to Their Radio Origins

The Astronomical Journal
We present an infrared, millimeter, and radio survey of 20 Class 0–III young stellar objects in the Ophiuchus A L1688 star-forming cluster, combining high-resolution (7–25 au) Very Large Array (VLA) and James Webb Space Telescope observations with ...

Subtle and Spectacular: Diverse White Dwarf Debris Disks Revealed by JWST

The Astrophysical Journal Letters
This Letter reports 12 novel spectroscopic detections of warm circumstellar dust orbiting polluted white dwarfs using the JWST Mid-Infrared Instrument (MIRI). The disks span 2 orders of magnitude in fractional infrared brightness and more than double the

Observing dust grain growth andsedimentation in circumstellar discs [PDF]

, 2011
In the present thesis, the observational effects of dust grain growth and sedimentation in circumstellar discs are investigated. The growth of dust grains from some nanometres in diameter as found in the inter- stellar medium towards planetesimal bodies some meters in diameter is an important step in the formation of planets.

Confined Circumstellar Material as a Dust Formation Site in Type II Supernovae

The Astrophysical Journal
We propose a model for dust formation in Type II supernovae (SNe) interacting with confined circumstellar material (CSM), motivated by recent time-domain surveys that have revealed a substantial fraction of SN progenitors to be surrounded by CSM ejected ...

Infrared emission towards SN 1987A, 11 years after outburst: Properties of the circumstellar dust

, 2002
Detailed models are presented for the late epoch mid infrared (MIR) emission from collisionally heated grains in the shocked circumstellar gas around SN 1987A.
