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 | Формирование планет | Молодые звездные объекты | Планеты-океаныHL Tauri is a young star surrounded by a disk of gas and dust where planets are forming. Scientists are interested in finding complex molecules like methanol in such disks because these molecules are important for the chemistry that could lead to life. Methanol is often found around other young stars, but its presence in planet-forming disks is rare.
In this study, researchers looked for methanol in the disk around HL Tauri, motivated by the detection of warm water vapor in the same region. T...

4. 3. 2026Звезды | Экзопланеты | Лавовые планетыK2-141 b is an ultra-short period planet, known as a lava world, that orbits very close to its star. This extreme environment causes one side of the planet to be extremely hot, covered by a magma ocean, while the other side remains much cooler and solid. Scientists used computer models to study how the planet's interior moves and how this affects volcanic activity, especially on the nightside, which is not directly heated by the star.
The rese...

These planets, called sub-Neptunes, orbit close to their star and offer a unique look at how planetary systems change in their early stages. Unlike many young systems where planets are locked in precise orbital patterns called resonances, the planets in TOI-2076 are near but not exactly in resonance, making their arrangement less stab...

Recent observations with the JWST telescope have directly imaged a planet far from the star and revealed detailed features in the disk, such as a sharply defined inner edge and an unusual horseshoe-shaped structure. These features suggest that the system's planets are shaping the disk in complex ways.
Researchers used c...

The host star is located 25.6 parsecs away. The planet was first identified by the TESS mission and confirmed with both TESS and ground-based observations. Analysis of the light curves shows that TOI-1080 b has a radius of about 1.2 times that of Earth and an equilibrium temperature of 36...

This approach, typically used for larger and hotter planets, was successfully applied to a smaller, more temperate world, demonstrating the capability of ground-based facilities to characterize super-Earth atmospheres.
The team confirmed the presence of hydrogen sulfide (H2S) i...

Surveying over 8,000 such stars, they identified 77 transiting planet candidates and measured how often planets occur as a function of their size, orbital period, and the amount of starlight they receive. The study found that each mid-to-late M dwarf hosts on average about 1.1 planets larger than Earth within 30 ...

Despite achieving a record-breaking contrast sensitivity at the planet’s expected separation, the planet itself was not directly imaged. The study updated the age of the host star epsilon Eridani to 1.1 billion years, which affects the estimated temperature of t...
Read article 2. 3. 2026Звезды | Молодые звездные объектыDO Tauri is a classical T Tauri star, a type of young star still surrounded by a disk of gas and dust. Researchers monitored DO Tau using the SPIRou spectropolarimeter at the Canada-France-Hawaii Telescope between 2020 and 2025, aiming to understand its magnetic activity and accretion processes.
The study detected strong, variable magnetic fields in DO Tau, including a rare magnetic polarity reversal—meaning the star's large-sc...

In 2021, astronomers observed a hot-type outburst in YY Herculis using the Himalayan Chandra telescope, focusing on changes that occur during the system's secondary minimum.
This study monitored YY Herculis from 2021 to 2023, covering one and a half orbital cycles. Researchers analyzed how the temperature and brightness...
