Stars | ExoplaneWASP-11 b, also known as HAT-P-10 b, is a hot Jupiter with a low density, making it a good candidate for studying its atmosphere. Researchers collected 31 new transit observations and combined them with previous ground-based and space-based data to refine the planet's properties and analyze its orbit over 16 years.
The updated analysis shows that WASP-11 b's orbit is stable, with no signs of orbital decay or additional planets affecting its motion. The team also studied the planet's atmospher...

12. 4. 2026Stars | Exoplanets | Red dwarfA new study has measured the alignment between the spin of an M dwarf star and the orbit of its very-low-mass stellar companion, marking the first such measurement for a double M dwarf system. Using the Rossiter-McLaughlin effect, researchers found that the two stars are well aligned, meaning the companion orbits in the same direction as the primary star spins. This suggests the system either formed aligned or was later realigned by tidal forces....
Read article 12. 4. 2026Stars | ExoplaneGJ 436 is a red dwarf star with a Neptune-sized planet, GJ 436 b, orbiting close by. Scientists have long suspected that magnetic interactions between such planets and their stars could produce detectable signals, but direct evidence has been rare. In this study, researchers analyzed 17 years of spectroscopic data and found repeated increases in the star's activity that match the planet's orbital period and the star's rotation.
The team develo...
Read article 12. 4. 2026Stars | ExoplaneHATS-75 b is a giant planet orbiting a red dwarf star, recently studied as part of a program using the James Webb Space Telescope. Scientists observed three transits of the planet, where it passed in front of its star, to analyze its atmosphere. The planet's spectrum showed a deeper transit at shorter wavelengths, which can be caused by hazes in the atmosphere or by features on the star's surface, such as starspots and bright regions.
By compa...
Read article 7. 4. 2026Stars | Young Stellar Objects | Planet formatioHL Tauri is a young star surrounded by a protoplanetary disk with rings and gaps, where planets may be forming. Understanding turbulence in such disks is important because it affects how material moves and how planets grow. Until now, the strength of turbulence in the outer parts of these disks was not well known, especially in systems still gathering gas from their surroundings.
Researchers used ALMA telescope data to study the disk around HL...
Read article 6. 4. 2026Stars | Exoplanets | James Webb Space Telescope | Planetary atmosphereGliese 3473 b (GJ 3473 b) is a rocky exoplanet orbiting close to its star, making it highly exposed to intense starlight. Scientists used the James Webb Space Telescope to observe the planet as it passed behind its star, a phenomenon called a secondary eclipse. These observations help reveal whether the planet has an atmosphere or if it is a bare rock, a key question for understanding how such worlds evolve under strong stellar radiation.

Read article 30. 3. 2026StarDO Tau is a young star surrounded by a disk of gas and dust, where planets may eventually form. This system is a T Tauri star, a type of young, Sun-like star still gathering material from its surroundings. By combining high-resolution infrared spectra and advanced imaging, researchers have studied the region where the star and its disk interact, revealing new details about how material moves from the disk onto the star.
The team used two main ...
Read article 30. 3. 2026Stars | Exoplanets | Super-EarthGJ 523 b (BD+39 2675 b) is a recently confirmed planet orbiting a mid-type orange dwarf star called Gliese 523. This planet is unusually massive for its size, earning it the classification of a mega-Earth. At just 170 million years old, GJ 523b is much younger than most known exoplanets, and it orbits its star every 17.75 days. Its high density suggests it has very little gas, despite its large mass, which is rare for planets of this size....
Read article 30. 3. 2026Stars | Exoplanets | TESS | Hot JupiterTOI-7169 b is a giant planet, known as a hot Jupiter, that orbits a star with very low metal content. Most planets are found around stars rich in elements heavier than hydrogen and helium, but TOI-7169 b challenges this trend by orbiting a metal-poor star. This discovery helps scientists understand how planets can form in environments with fewer heavy elements.
The planet was detected using data from the TESS space telescope and ground-based o...
Read article 30. 3. 2026Stars | Exoplanets | Planetary atmosphereK2-18 b is a temperate sub-Neptune planet orbiting a red dwarf star, making it a key target for understanding atmospheres beyond our Solar System. Recent observations with the James Webb Space Telescope have provided new insights into its atmospheric composition and structure, helping to bridge the gap between planets like Neptune and the more commonly studied hot-Jupiters.
Researchers used a detailed computer model to study K2-18 b's atmosphe...
