Feedback in low-mass galaxies in the early Universe
... As exemplified by M82, the archetypal starburst described above, detailed observations of galactic outflows in the local Universe reveal that they are a complex, multi-phase phenomenon, with outflows observed in hot gas traced by X-rays51,52, ionized gas seen via optical emission lines53, neutral ga ...

The molecular disk surrounding the protostellar binary L1551 IRS5
... the L1551 IRS5 region. In this figure we can see a somewhat flattened structure with its major axis more or less perpendicular to the outflow axis. In addition, at least two discrete “clumps” can also be identified at positions of +2000 , −6000 and at +6000 , +2000 (see text below). In the left bott ...

Another possibility is that high-mass stars are formed in regions so densely crowded that dense cores begin to merge, with protostars already inside collapsing into one another under their own gravity. While mechanisms that produce high-mass stars have been proposed, their scarcity and ...

The occurrence of a runaway greenhouse for increased stellar insolation and surface temperatures is determined by the application of radiation limits of the outgoing infrared flux in previous studies. If the stellar flux exceeds this radiation limit, the surface temperature of the planetary atmosphere ...

Microplasma
Microplasmas are plasmas of small dimensions, ranging from tens to thousands of micrometers. They can be generated at a variety of temperatures and pressures, existing as either thermal or non-thermal plasmas. Non-thermal microplasmas that can maintain their state at standard temperatures and pressures are readily available and accessible to scientists as they can be easily sustained and manipulated under standard conditions. Therefore, they can be employed for commercial, industrial, and medical applications, giving rise to the evolving field of microplasmas.
