Astronomers detect methane in the atmosphere of the dwarf star closest to the earth

Scientists found methane in the atmosphere of Wisa J181006.18 −101000.5, the t dwarf closer to the earth. The study was published in the ARXIV Online Prepression Journal on March 28, and the final and revised version was published on November 17. The WEDE1810 is a dwarf planet of metal, located at a distance of 29 light years from Earth. The effective temperature of the dwarf is reported in the range of 800 to 1,300 K.

The signing of methane surprises astronomers

According to a Phys.org reportThe discovery is very possible by the present 10.4 m of telescope sugarcanes (GTC). Methane detection in the dwarf planet’s atmosphere has further classified as T -type ra instead of type L, which was previously suggested in previous studies, observes the publication. The study also reveals that there are no traces of carbon monoxide and potassium in the WISE1810 atmosphere.

The study also highlights that carbon abundance on the planet is estimated at -1.5 Dex, while the effective temperature may be around 1,000 K. The author of the article also revealed that the low metality of the planet of the dwarf may be due to non -detection of atomic potassium. However, a lower temperature can also increase this effect, the report highlights even more. The study also found that the Wise1810 has a heliocentric speed of -83 km/s.

The 10.4 m (GTC) gran telescope provides a significant contribution to the finish of Wisea J181006.18-101000 observations. Interestingly, the previous observations of the dwarf platent suggested that the atmosphere of the dwarf planet was dominated by hydrogen and water vapor. In addition, the study also reveals that the findings indicate that the Wise1810 could be more likely to be associated with the thick disc of the Milky Way, despite its very low metality.
