As per reports from an international team of researchers, few concentric rings were discovered in the series structure in the debris disk of a young nearby star called HIP 73145. The concentric rings are found to be situated at a few radial distance.

According to the Phys Org, the young nearby star called HIP 73145 is also known as HD 131835 and it is situated at 400 light years away from earth and 15 million years old star. HIP 73145 is having solar radii of 1.38 and is heavier than the sun.

This star, HIP 73145 hosts a debris disk of approximately 96 AU radius. This debris disk was found in the year 2015 in scattered light in near infrared and at far-infrared wavelengths. Within these observations, no other structures were found.

The ECN says that a team of astronomers conducted an observation with multi-wavelength light which made a distinguishing discovery of a series of concentric rings in the debris disk of star HIP 73145. The first detected ring has a radius of 66 AU following other spotted structures of 35 AU and 45 AU in radius.

The most probable reason of forming these ring-like structures in the debris disk of the star can be caused by planets or by dust gas interaction, as per the reports. In the observation, it was also seen that the dust composition of the debris disk of HIP 73145 is influenced by carbon, and the star is composed of the large amount of dust and gas, which can be because of its old age.

It has still not been cleared that the concentric rings in the debris disk of HIP 73145 aka HD 131835 has been formed by the planet interaction or just by dust-gas interactions. The huge composition of the dust and gas content is sufficient to explain the possible structures to be formed. 

The international team of researchers who discovered the concentric rings around young star HIP 73145 are not sure about the structure of rings in the debris disk.
