Stellar Brief: 20. 10. 2026
Today’s standout finding changes the story of PDS 70: the young star is estimated to be 12 to 16 million years old, about three times older than previously thought. Alpha Centauri was the leading Stellarcatalog search query, with 1,537 impressions on October 19.

Звезды | Экзопланеты | | Атмосферы планетAstronomers have successfully analyzed the atmosphere of HAT-P-44 b, a gas giant similar in size and temperature to Saturn, located in a tight orbit around its star. Using the William Herschel Telescope, the team detected the chemical signature of sodium and found evidence of water vapor within the planet's envelope.
The findings suggest the planet has a relatively clear atmosphere at high altitudes, free from thick clouds, and a chemical composition richer in heavy elements than our own Sun...

24. 2. 2026Звезды | Экзопланеты | Красные карликиA new study reveals that the surface terrain of rocky planets orbiting M-dwarf stars plays a crucial role in their climate and habitability. These planets are often tidally locked, meaning one side always faces the star while the other remains in darkness.
Researchers found that steep mountains and high plateaus create stationary atmospheric waves that disrupt air circulation. This process strengthens winds that carry moisture to the cold nig...

Despite its similarities to our own Neptune, this world orbits its red dwarf star so closely that its year lasts only 2.6 days.
New high-resolution observations found no traces of expected gases like water vapor or methane, leading scientists to conclude that the planet is either shrouded in extremely high-alt...
Read article 23. 2. 2026ЗвездыAstronomers monitoring the active red dwarf AD Leo recently watched for a rare event: a total reversal of its magnetic poles, similar to the 11-year cycle seen on our Sun. However, the 'flip' failed to happen. Instead, the star's magnetic field simplified and strengthened into a more stable configuration.
Despite this lack of a reversal, the study shows that AD Leo is a violent neighbor; it loses mass through stellar winds at a rate ten times...
Read article 23. 2. 2026Звезды | ЭкзопланетыResearchers have discovered that the magnetic field of the giant planet WASP-18 b plays a dramatic role in controlling its weather. Because the planet is so close to its star, its atmosphere becomes 'ionized' or electrically charged.
This allows the planet's magnetic field to act like a physical brake on high-altitude winds, creating a 'stop and go' effect in the atmospheric flow. This magnetic drag, combined with frictional heating, creates ...

Despite being about twice the size of Earth and nine times its mass, the planet has a density remarkably similar to our home world. This suggests that TOI-5734b is likely a rocky planet that has lost most of its original atmosphere due to the heat of its nearby young star.
Located in a system only about 5...

By tracing the movements of 39 high-latitude B-type stars and nearly 450 star clusters using Gaia satellite data, researchers have successfully linked five of these 'orphaned' stars to their original birthplaces.
These stars were likely kicked out of their home clusters millions of years ago at high...

Located about 119 light-years away, this star is a much more active version of our own Sun as it appeared in its youth.
The study revealed a glowing halo of X-rays extending 220 astronomical units wide, caused by the star's wind crashing into t...
Read article 21. 2. 2026Звезды | ЭкзопланетыA new study using the ESPRESSO spectrograph has provided a precise look at the giant exoplanet WASP-31 b. Researchers confirmed that the planet’s orbit is nearly perfectly aligned with its star's rotation. While attempting to scan the planet's atmosphere for chemical elements, the team found that the signal was heavily obscured by distortions caused by the planet passing in front of its star. Although previously suggested elements like potassium ...
Read article 21. 2. 2026Звезды | Экзопланеты | TESSResearchers have discovered two new gas giant planets, TOI-883 b and TOI-899 b, which are similar in mass to a 'light' Saturn. These 'warm' giants orbit stars very much like our own Sun with orbital periods of approximately 10 and 11 days.
Despite their similar sizes and environments, the two planets appear to have different internal compositions. This suggests they may have followed different evolutionary paths, providing a unique opportunit...
