For the first time discovered the 'heartbeat' of the mysterious star

According to a study published in Nature this week, new data from the space telescope for NASA's Explorers (TESS) program reveals the exact model from inside of dozens of nearby stars.

'Previously, we have found too many confusing records to properly understand these wavering stars' - CBS News quoted the study's lead author - Professor Tim Bedding from the University of Sydney. ' It's a mess like hearing a cat walking on the piano '.

The Delta Scuti star is named after a star in the constellation Scutum, which is 1.5 to 2.5 times the mass of the Sun. Although researchers are aware that these stars may have "heartbeats", they have not previously been able to detect any pattern of beats.

After looking at thousands of stars, the team found 60 stars, which are located about 60 to 1,400 light-years from Earth, with regular high-frequency pulses, essentially like a beating heartbeat. . One of the stars studied, beta Pictoris , is only 60 light-years from Earth and is visible to the naked eye in Australia.

'Accurate data from TESS has allowed us to cut down on noise and be able to detect structures, listen much better than an excellent piano track , ' Professor Bedding said.

These elusive beats are due to the energy accumulated and released inside the stars, usually in two main categories. The scientists noted that some of the stars they studied were surprisingly close to others.

Observation results show that this star class is very young and tends to hang around in loose links. They have no idea about the rules of "social spacing" - Professor Bedding said.

The researchers said that exploring seismic planets on the planet is like looking inside a star and looking at the structure inside them. The discovery could help explain the inner workings of billions of stars across the universe.
