Scientists discovered organic acid in a protoplanetary disk

The age of the star is about 10 million years, so a protoplanetary disk and one massive Jupiter-like planet have formed around it, but an Earth-type planet has not yet formed. This gives a very rare opportunity to look into the era of the formation of solid earth-like planets, like our own, especially since the orange dwarfs are relatively close in weight and spectrum to the yellow ones, to which our Sun belongs.

The importance of the finding is that the organic acid is much more difficult to obtain than other organic molecules found in protoplanetary discs before. If methanol is obtained from carbon monoxide on the surface of dust particles under stellar radiation, then formic acid requires more complex reactions, which are not possible without active processes of organic synthesis.

'We have found formic acid in the protoplanetary disk surrounding the young sun-like star TW Hydra. The finding implies that rich organic chemistry, which can lead to the formation of larger organic molecules, probably takes place at the base of the formation of planets in protoplanetary disks,' says the researchers.

'Formic acid along with methanol and formaldehyde are the most common complex molecules found in protoplanetary disks. In the context of interstellar communication, this shows that at least some of the components of prebiotic chemistry are present in the protoplanetary disk, which is expected to be similar to the solar nebula that formed our solar system.'

Thus, the discovery may indicate an active process of organic synthesis long before the formation of the planets. This means that immediately after the appearance of celestial bodies, large amounts of organic compounds must already be present in their primary material.

The results are extremely important for understanding the specific conditions under which the emergence of life takes place at an early stage in the development of planetary systems. It is known that formic acid is the basis for the synthesis of more complex carboxylic acids actively used by earth life.

We would like to note that the observation of the protoplanetary disk of the young orange dwarf TW Hydra located 176 light years from the Earth was conducted by the ALMA radio telescope (Atacama Desert in Chile).

The age of the star is about 10 million years, so a protoplanetary disk and one massive Jupiter-like planet have formed around it, but an Earth-type planet has not yet formed. This gives a very rare opportunity to look into the era of the formation of solid earth-like planets, like our own, especially since the orange dwarfs are relatively close in weight and spectrum to the yellow ones, to which our Sun belongs.

Impact of a stellar intruder on our solar system
Bonn, Germany (SPX) Aug 10, 2018
The solar system was formed from a protoplanetary disk consisting of gas and dust. Since the cumulative mass of all objects beyond Neptune is much smaller than expected and the bodies there have mostly inclined, eccentric orbits it is likely that some process restructured the outer solar system after its formation. Susanne Pfalzner from the Max Planck Institute for Radio Astronomy in Bonn, Germany, and her colleagues present a study showing that a close fly-by of a neighbouring star can simultaneo ... read more
