Stars | ExoplaneThe disk surrounding the star HD 135344B shows clear signs of active planet formation, including complex spiral arms and a gap in the surrounding dust. By tracking these features over a ten-year period using various telescopes, researchers have identified a consistent orbital motion that links the spiral structures, a central dust gap, and a mysterious twist in the disk. This evidence suggests that a single, yet-to-be-seen protoplanet is likely responsible for shaping these features.

21. 6. 2026StarDeuterium is a heavier version of hydrogen that is typically destroyed by nuclear fusion in the interiors of stars. Because of this, it is not expected to appear in the light emitted from a star's surface, or photosphere. However, early-type stars, which include B, A, and F-type categories, have outer layers that mix slowly. This property might allow recently accreted material containing deuterium to survive long enough to be detected in spectral...
Read article 20. 6. 2026Stars | ExoplanePhotochemical haze—tiny solid particles formed by chemical reactions triggered by starlight—plays a critical role in shaping the appearance and environment of exoplanetary atmospheres. A new 3D model was applied to the well-studied exoplanet HD 189733b to understand how these particles form, move, and affect the planet's overall temperature and light-blocking properties over time.
The simulation used a microphysical scheme coupled with a gener...
Read article 20. 6. 2026Stars | ExoplaneThe internal state and atmospheric composition of rocky planets are heavily dictated by the exchange of gases between a molten mantle and the air above it. For planets orbiting very close to their stars, this process can continue for billions of years. A new analysis of the super-Earth Gliese 1132 b examines how the oxidation state of a planet's interior—specifically how oxygen availability affects the melting point of rocks—changes how these wor...
Read article 20. 6. 2026Stars | Massive main-sequence starHD 48914, also known as V505 Mon, is an eclipsing binary star system consisting of a Be-shell star—a star surrounded by a shell of gas—and a companion star that has lost much of its outer material. This system demonstrates high-speed rotation and complex interactions between the two stars. By combining new observations from the TESS space mission with existing photometric data—measurements of light brightness over time—and radial velocity data, t...
Read article 20. 6. 2026Stars | ExoplaneGliese 367 b is an ultra-short-period planet that orbits its host, a Red dwarf star, in just 7.7 hours. Because it is located only about 9 parsecs (roughly 29 light-years) from Earth, it has been a target for intense study. Previous research suggested the planet possessed an extremely high density, implying it might be composed almost entirely of solid iron, a finding that challenged standard models of how planets form. New, high-precision measur...

Previously too faint for detailed study from the ground, this object has now been analyzed using the James Webb Space Telescope. The data reveal a complex atmosphere filled with various molecules and evidence of salt clouds, providing a rare look at the chemistry of a cool, directly imaged world.

Read article 20. 6. 2026Stars | ExoplaneWASP-121 b is an ultra-hot Jupiter, a gas giant planet orbiting extremely close to its host star. Because it is tidally locked, meaning the same side always faces its star, the planet experiences extreme temperature differences across its surface. New observations show that the planet's rotation creates detectable changes in the light it absorbs as it passes in front of its star, revealing uneven temperature and chemical distributions.
Data fr...
Read article 20. 6. 2026Stars | ExoplaneWarm Jupiters are gas giant planets with orbital periods between 10 and 200 days. Two such planets, TOI-2147 b and TOI-6019 b, have been identified and characterized. These planets exhibit high orbital eccentricity, meaning their paths around their host stars are more oval-shaped than circular. Their characteristics suggest they migrated to their current positions through processes involving high-eccentricity interactions.
The planetary nature...
Read article 20. 6. 2026Stars | ExoplaneTOI-837 b is a young, Saturn-sized planet located in the IC 2602 cluster, which is only 35 million years old. By studying the spin-orbit obliquity—the angle between the axis of the planet's orbit and the axis of the host star's rotation—researchers can determine how planets migrated to their current positions. This planet is the first younger than 100 million years observed to have a measurable misalignment, providing a rare look at planetary evo...
