A team from Tsinghua University has brought to light an extraordinary binary system, called TMTS J0526, using the TMTS telescope (Tsinghua University-Ma Huateng Telescope for Survey) .
Located approximately 2,760 light years from our planet, this system consists of a woman blanche (A white dwarf is a gaseous celestial object resulting from the evolution of a star…)vestige stellar (Stellaria is a genus of annual or perennial herbaceous plants, starworts,…) rich in carbone (Carbon is a chemical element of the crystallogens family, with the symbol C,…) et oxygène (Oxygen is a chemical element from the chalcogen family,…)and a étoile (A star is a celestial object emitting light autonomously, similar to a…) extremely warm and small subdwarf. This celestial duo is distinguished by a cosmic dance at vitesse (On distingue 🙂 astonishing, the smallest star completing an orbit every 20.5 minutes (First form of a document: Law: a minute is the original of an act. …) around the largest, or for this star the equivalent of 72 years in a single Earth day.

This discovery not only challenges our understanding of stellar dynamics; it also offers a valuable insight into the formation of subdwarfs, one of the most mysterious categories of stars in the world.Universe (The Universe is the totality of everything that exists and the laws that govern it.). The white dwarf of TMTS J0526, with a mass equivalent to 74% of that of the Sun, exerts considerable gravitational influence on its subdwarf companion, which, despite its tiny size – regarding seven times that of Earth and therefore smaller than Jupiter – shines with remarkable intensity.
In addition to this, there is a phenomenon of deformation of the subdwarf star into an ellipsoidal shape under the effect of the gravity of the white dwarf, illustrating the power (The word power is used in several areas with a particular meaning 🙂 forces at play in these compact binary systems. In addition, the study of TMTS J0526 might shed light on the processes behind the creation of subdwarfs, these stars born from the expulsion of their envelope during a explosion (An explosion is the rapid transformation of one matter into another matter having a…) thermonuclear explosion at the level of the white dwarf, a category of explosion less powerful than a supernova (A supernova is the set of phenomena resulting from the explosion of a…).
This study, published in the journal Nature Astronomyrepresents a significant advance in our quest to understand the mysteries of the Universe, highlighting lumière (Light is all electromagnetic waves visible to the eye…) the complex processes that govern the life and death of stars.
