Catalog – Tech-Science – Traces of a space object piercing a young star system have been found

Traces of an alien orb that flew in the immediate vicinity of the emerging double star, called Canis Majoris (Z CMa), were discovered by an international research team, and Hungarian astronomers were also involved in the discovery.

A publication presenting the researchers’ findings was published in the journal Nature Astronomy Thursday, the ELKH Research Center for Earth and Astronomy Sciences (CSFK) informed MTI.

Peter Abraham, Lee Chen, and Agnes Cospal participated in the research on behalf of ELKH CSFK. Astronomers used three high-performance binoculars and a wireless antenna system to take pictures of one of the young stars in the constellation Canis Major, which can also be seen in Hungary on winter evenings.

We can say from the report that the images indicate that the disk of dust and gas around the star in the system has been subjected to external influences.

The structure of the elongated bridges of material shown in the images indicates that a strange celestial body flying in the immediate vicinity of the star Z CMa may have disturbed the homogeneous structure of the disk.

The shape and direction of the bumps helped researchers identify the “intruder.” Numerical modeling showed that the newly discovered faint point source in the images and the gravitational interaction of the Z disk CMa explain the observed bridges of material.

The flight of a strange celestial body near a star raises exciting questions about the evolution of young stars and the fate of the planets born in its disk. Based on theories, this phenomenon has been predicted before, and Z CMa is one of the very rare cases in which it has been observed.

– A highlight in the connection, adding that one of the exciting features of the Z CMa double star system is that both of its stars show unexpectedly high levels of brightness from time to time.

The fact that an outer celestial body passes near a young star system may explain the luminosity. As a result of the gravitational interaction, part of the disk material falls on the star embryo in a short time, increasing its brightness up to a hundredfold and affecting the development of the resulting planetary spores. “

– explains Ágnes Kóspál, one of the publication’s co-authors.

Rubing Dong, a leading astronomer at Victoria University in Canada, points out Learning about the origin and evolution of young star systems in the Milky Way opens the way to a better understanding of the prehistoric times of our solar system. Studies like CMa may help reveal the early history of the Solar System, whose immediate memories have long since vanished.

The 8.2-meter Subaru Optical Telescope is located in Hawaii, the Jansky Very Large Array Radio Telescope Network is located in the United States, and the Atacama Large Millimeter/submillimeter Array (ALMA) is located in Chile.

One of the main areas of research at CSFK is the study of the formation of stars and their planets. According to the report, by studying the Z CMa, Hungarian researchers have made a significant contribution to both the preparation of ALMA antenna system measurements and the determination of the star system’s distance.
