Nitrogen deficiency in maize: Annotated image classification dataset [PDF]
Data in Brief, 2023 Nitrogen (N) is one of the key inputs in maize production applied in the form of fertilizers. Nitrogen deficiency during the vegetation period leads to lower yields since N is utilized in proteins and enzymes that enable important biochemical processes ...

Disk Wind Feedback from High-mass Protostars. II. The Evolutionary Sequence [PDF]
The Astrophysical Journal, 2023 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 be important for regulating the efficiency of star formation from a natal ...

An Outbursting Protostar: The Environment of L1251 VLA 6 [PDF]
The Astrophysical JournalYoung protostars that undergo episodic accretion can provide insight into the impact on their circumstellar environments while matter is accreted from the disk onto the protostar.

JWST-IPA: Chemical Inventory and Spatial Mapping of Ices in the Protostar HOPS 370—Evidence for an Opacity Hole and Thermal Processing of Ices [PDF]
The Astrophysical JournalThe composition of protoplanetary disks, and hence the initial conditions of planet formation, may be strongly influenced by the infall and thermal processing of material during the protostellar phase.

A magnetized protostellar jet launched from the innermost disk at the truncation radius [PDF]
Scientific ReportsProtostellar jets form when part of the accreting material is energetically ejected from the vicinity of protostars. Understanding where and how they are launched and collimated is crucial to determining their role in the accretion process.

First Detection of Circular Polarization in Radio Continuum Toward a Massive Protostar
The Astrophysical Journal LettersPolarization measurements provide strong constraints on magnetic fields in star-forming systems. While magnetic field estimates of a few kG have been obtained near the surfaces of low-mass protostars, there are no analogous measurements in the immediate ...

Unveiling a magnetized jet from a low-mass protostar [PDF]
Nature Communications, 2018 The presence of magnetic fields in protostellar jets has been predicted theoretically, but its experimental confirmation has been elusive so far. Here, the authors report the detection of SiO line polarisation in the HH 211 protostellar jet, indicative ...

The Astrophysical Journal, 2010 We explore the origin of a population of distant companions (~1000 - 5000 AU) to Class I protostellar sources recently found by Connelley and co-workers, who noted that the companion fraction diminished as the sources evolved. Here we present N-body simulations of unstable triple systems embedded in dense cloud cores.
