Astronomers image four protostars in the Perseus molecular cloud

(ORDO NEWS) — Astronomers have observed four protostars in the Perseus molecular cloud.

Molecular clouds are giant accumulations of rarefied interstellar matter, whose density is sufficient to form hydrogen molecules from atoms.

They are considered the “cradles” of stars – the luminaries are obtained as a result of the gradual compression of such a cloud under the influence of gravitational forces and heating.

One such object is the Perseus cloud. It is removed from the Earth by about 1000 sv. years and contains 10,000 solar masses of gas and dust.

Now, astronomer Erika Behrens and her colleagues have studied four protostellar cores in the Perseus cloud.

They observed the movement of the gas surrounding these nuclei at radio frequency using the ALMA telescope in Chile and the Green Bank Telescope.

It turned out that one of the protostars has a traditional disk, but the other three are part of a triple system, and the movement of gas around them is chaotic.

Moreover, the movement of the gas is too chaotic to be explained only by the rotation of the core itself.

With further study, Erica and her team will be able to learn more about this system, such as where gas flows in and out of it, and how the three protostars interact with each other.
