Scientists decode mystery of 'brown dwarfs'

The team named five companions that were originally identified with the Transiting Exoplanet Survey Satellite

Scientists from different countries formed a team and identified five objects. Those objects are named as “brown dwarfs" which are astronomical objects with masses between those of planets and stars.

 

Nolan Grieves, a researcher in the Department of Astronomy at the University of Geneva (UNIGE) said, “We still do not know exactly where the mass limits of brown dwarfs lie, limits that allow them to be distinguished from low-mass stars that can burn hydrogen for many billions of years, whereas a brown dwarf will have a short burning stage and then a colder life."

 

The team named five companions that were originally identified with the Transiting Exoplanet Survey Satellite (TESS) as TESS objects of interest (TOI) — TOI-148, TOI-587, TOI-681, TOI-746 and TOI-1213.

 

They are named as ‘companions’ because they orbit their respective host stars with periods of five to 27 days. This places them on the borderline between brown dwarfs and stars.

 

According to scientific researchers, these new discoveries contain valuable data which will help them to find much unknown information about space. The discoveries and findings are detailed in the journal Astronomy and Astrophysics.
