Stars | Massive main-sequence starResearchers have closely examined HD 188101, a little-studied star with a weak magnetic field, using both spectroscopic and photometric observations. This star has properties typical of main-sequence B9 stars, including its effective temperature and surface gravity. The study focused on measuring the amounts of several elements in the star's atmosphere and how these compare to the Sun.
The team found that HD 188101 has higher than solar amounts of silicon, titanium, and strontium, while its h...

6. 3. 2026Stars | Sun-like starA new approach has been developed to measure the movement of stars by analyzing their light in detail. This method does not rely on a reference template, which can sometimes introduce errors, especially when the data is not perfect. It is designed to work with different types of stars and instruments, making it flexible for various astronomical studies.
The method, called TILARA (Template-Independent Line-by-line Algorithm for Radial velocity ...
Read article 6. 3. 2026Stars | Exoplanets | Super-Earths | Orange dwarfHD 93083 (Gliese 1137) is a orange star already known to host a Saturn-mass planet, HD 93083 b. In this study, scientists analyzed 13 years of precise spectroscopic data to search for new planets and improve our understanding of the known planet's properties.
The team refined the orbital parameters and minimum mass of HD 93083 b, providing a more accurate picture of this Saturn-mass exoplanet. In addition, they discovered a new planetary candi...
Read article 5. 3. 2026Stars | Exoplanets | Red dwarfM dwarf stars are small, cool stars that are popular targets for finding exoplanets because their size makes it easier to detect planets in their habitable zones. However, these stars often have magnetic activity that can mimic the signals of planets, making it important to understand their activity cycles. This study focused on two M dwarfs, Gliese 617 A and Lalande 21185 (Gliese 411), both known to host exoplanets.
Researchers analyzed 13 ye...
Read article 5. 3. 2026Stars | Planet formation | Exoplanets | Massive main-sequence starβ Pictoris is a well-known star surrounded by a disk of dust and debris, making it a prime example for studying how planetary systems evolve. By observing this disk at different wavelengths, scientists can learn about the structure and behavior of the material around the star. This study focused on measuring the vertical height of the disk using images from mid-infrared to millimeter wavelengths.
Researchers used advanced modeling to analyze t...
Read article 5. 3. 2026Stars | Exoplanets | Planet formation | Young Stellar Objects | Ocean planeHL 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 d...
Read article 4. 3. 2026Stars | Exoplanets | Lava planeK2-141 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...
Read article 4. 3. 2026Stars | Exoplanets | Planetary atmosphereTOI-2076 is a young star system, about 200 million years old, that hosts four planets slightly larger than Earth. 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...
Read article 4. 3. 2026Exoplanets | Young Stellar Objects | Planet formation | Stars | James Webb Space TelescopeTWA 7 is a young star surrounded by a debris disk, which is a ring of dust and small objects left over from planet formation. 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...
Read article 3. 3. 2026Stars | Exoplanets | TESS | Red dwarfResearchers have detected and validated TOI-1080 b (SIPS J1825-5212 b), a small, temperate exoplanet that transits its quiet M4V host star every 3.97 days. 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...
