One Star Is Orbiting Inside Another in This Never-Before-Seen Binary System

For the first time, a astronomer was a neutron star that rotates rapidly, a helium star saw a neutron star attached to his wife. The discovery of this unusual binary system helps to confirm a long theory, but rarely the spacecraft – the general envelope evolution was named.

Double star systems or couple stars, which are orbit around each other, are common. In fact, 85% of the stars in the universe are estimated to have at least one companion. However, unlike anything that has been done before this newly discovered pair.

In this case, a helium star is connected with a millisecond pulsar: a fast neutron star that regularly spreads radiation rays. These stars get extraordinary rotation rates by siphoning the issue of a nearby starforem.

In May 202020, a researcher in the National Astronomical Observatory and a Radio Astronomical Academy of Sciences Jin Lin Han, a group led by Gin Lin Han, Milky Way Galaxy has used a deep point to detect weak signals.

After a few months, researchers confirmed that these signals were radiation waste from a gain. Then they watched these explosions for four and a half years and the measurements revealed that this star was not alone. This is part of a companion every 3.6 hours, part of a binary system. However, for the sixth of that orbit, the pulsar’s radiation is blocked or held by his wife.

“This is a big part of the orbit,” Han said gizmodo. “It’s weird, only a bigger companion can do it.”

In binary systems, a millisecond pulsar is generally accompanied By the White Dwarf: After a star like our Sun, a hot and intense core of a hot nucleus exhausted. However, the information was said to be a compact object in Han and his colleagues and had to sleep together between a normal star.

The further investigation of this strange wife, it cannot be as massive as massive, but can not be a normal star, because the radio spectrum cannot be found on the edges of all the divers. This realized that the researchers were cleaned of a star’s hydrogen, primarily from a core of Helium. Today they published speeches in the magazine Science.

This type of dual system said “previously detected” Han. However, so many couples were thinking that they could occur with the evolution of the general envelope and have what happened here with their colleagues.

“The General Envelope Evolution process, stars interacting in dual systems such as pulsaries,” Duncan Lorimer, Duncan Lorimer, who is a professor of physics and astronomy at the University of West Virginia, said in an e-mail.

Normally, the closeness of a neutron star, the area of ​​the lawn star “eaten” by the neutron star of the lawn star. This process, called Acredit, can “scroll” and a pulsara.

However, in the evolution of the general envelope, the “friends star is so great that the outer layers also covered the neutron star,” the lorimer said. “It acts as a brake in the whole binary system.”

Among the exterior of the exterior of the Star, this causes a high-compact double system, such as a Han and colleague, the pulsar and his husband’s core. This pulsar with a total of 3.6 hours orbital and its companion filled each other very closely.

As a result, the outer layers of the folk stars, Lorimer’in this milli-winning Helium star wife said Lorimer said he was celebrated.

“The evolutionary way of the authors depart is not a surprising way,” he said. “Recognized, identified and detailed in detail for years.”

“An interesting question, if you intend to find 1000 millisecond pulsaries, what part of these will be like this? It’s about 1000 things like this.” Said.

Han and his colleagues believe that the presence of more than one other system, making them exclusive. The researchers said that they find one of them “great progress” Lorimer.

“We find more than millisecond pulsars, find examples of rare evolutionary consequences. This system is an excellent example of this,” he said.
