Researchers discover strange signals emitted by a dusty object

Every day and non-stop, several satellites and telescopes scan the sky in search of new mysteries to solve. NASA’s Transiting Exoplanet Survey Satellite

, better known as TESS, is one of the satellites made available to scientists. Among the information obtained by TESS, scientists have come across a new mystery that does not show any characteristics of the bodies already spotted.

A team of scientists is studying the potential causes of the unusual signals emitted by an object dubbed TIC . TIC is the abbreviation of

TESS Input Catalog and refers to a database. The researchers, after having better studied the signals, have put forward several hypotheses to explain that they are very different from those generally obtained.

They suggest that the source could be a binary star or the debris from a large asteroid. They also thought of the possibility of a double star where one of the stars would be surrounded by a massive cloud.

A new feat of the transit method

The role of the TESS satellite is to locate exoplanets by looking for tiny decreases in brightness of a star. These drops are due to the passage of a planet between the telescope and the star. This passage blocks a small part of the light of the star. But the planets are not the only phenomenon likely to cause such dips in brightness.

When researchers studied the data collected at the beginning of the year 1920, the object stood out. This because he lost close to 96% of its brightness in a short time. It then underwent several other sudden brightness changes. Today, it has become a puzzle for scientists. To better explain the nature of ICT 150015880, researchers have resorted to other scientific instruments.

Spruce stands resulting from planetary collisions?

All the data collected allowed scientists to get an idea of ​​what could be at the origin of the strange signal. Researchers believe that at the heart of TIC 150015880 is a binary star in which two similar stars surround each other. But one of these stars seems to have slow pulsations, which makes the study very complicated.

According to the scientists, these pulsations are due to a massive cloud of dust which surrounds the star. These researchers are considering several hypotheses to explain the presence of this amount of dust. They believe that this is due to collisions between objects resembling planets or asteroids. They hope to continue observing the object in order to better understand its strange characteristics.
