Protein–protein complexes are formed via transient states called encounter complexes that greatly influence the formation of the stereospecific complex.

The largest genus within the Phyllanthaceae family is a group called Phyllanthus L. Recent studies have shown, that Phyllanthus is paraphyletic with the genera Glochidion, Breynia and Synostemon nested within it.

To study how planetary systems come into existence we study much younger systems still in formation.

Complex Organic Molecules (COMs) have been detected in objects across different stages of stellar evolution.

The high velocity tail of the total velocity distribution of stars provides essential insight into fundamental properties of the Galaxy.

Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.
