Stars | Young Stellar ObjeAstronomers have discovered that the unusual star HP Tau/G2 is likely the result of two stars crashing into each other. This 'walkaway' star is currently speeding away from its birthplace alongside another star, KPNO 15, after a complex gravitational dance in a multiple star system caused them to be ejected 5,600 years ago. HP Tau/G2 exhibits strange characteristics for its age, including an oddly large size, fast rotation, and a flattened shape.
The study suggests that after the ejection, t...

15. 2. 2026Stars | ExoplaneScientists have developed a new technique called the Variable Planetary Infrared Excess (VPIE) method to study exoplanets that never transit (pass in front of) their host stars. By analyzing how the total light from a star system changes as a planet orbits and shows different phases—much like the Moon's phases—this method can isolate the planet's heat signature without needing a complex model of the star itself.
Tests using simulated James We...
Read article 15. 2. 2026Stars | Exoplanets | Gaia | Young Stellar Objects | Planet formatioUsing high-precision data from the Hipparcos and Gaia satellites, researchers have analyzed 11 young star systems surrounded by transition disks to find hidden orbiting bodies.
The study successfully detected companions in several systems, including confirmed low-mass stars or sub-stellar objects around HD 142527, AB Aurigae, and MWC 758. In other cases, such as TW Hya and HD 100453, the lack of detection allowed scientists to set strict mass...
Read article 15. 2. 2026Stars | Exoplanets | Planetary atmosphereAstronomers have peeked into the atmosphere of HD 80606 b, one of the most unusual gas giants known due to its incredibly stretched, eccentric orbit. As the planet swings extremely close to its parent star—reaching a distance of just 0.03 AU, much closer than Mercury is to our Sun—it experiences rapid, intense heating. Using high-resolution spectroscopy from the Keck Observatory, researchers looked for signs of chemical changes during this therma...
Read article 13. 2. 2026Exoplanets | TESS | Stars | Super-EarthA statistical analysis of 132 planetary systems reveals a strong architectural link between giant outer planets and smaller inner worlds. Researchers found that stars hosting a 'cold Jupiter'—a gas giant orbiting far from its sun—are significantly more likely to also host 'hot super-Earths' in close-in orbits.
The study suggests that approximately 87% of these giant planet systems also contain at least one smaller rocky planet closer to the s...
Read article 13. 2. 2026Stars | Exoplanets | Red dwarfNew analysis of the four-planet system surrounding the red dwarf LHS 1903 provides a rare look at how planets form when gas is scarce. While the inner planets possess varying atmospheric thicknesses, the outermost world, LHS 1903 e, stands out because it completely lacks a gaseous envelope despite its distant orbit.
This suggests that the planet likely formed from material already depleted of gas, rather than losing its atmosphere later in li...
Read article 13. 2. 2026Exoplanets | StarA new study using the BOREAS model reveals how sub-Neptune planets can transform their atmospheres over hundreds of millions of years. By analyzing how different elements escape into space, researchers found that lighter hydrogen is often stripped away while heavier oxygen remains trapped. This process, known as chemical fractionation, can gradually turn a gas-poor envelope into a water-rich atmosphere. The findings suggest that planets like GJ 9...
Read article 12. 2. 2026Stars | | ExoplaneUsing the advanced HiRISE instrument at the Very Large Telescope, astronomers have performed a detailed analysis of 51 Eridani b, one of the faintest directly imaged planets ever found.
By measuring the planet's radial velocity across four different time periods, the team successfully mapped its full 3D orbit, breaking previous uncertainties. They discovered that the planet follows a highly stretched, or eccentric, path rather than a circular...
Read article 12. 2. 2026Stars | ExoplaneAstronomers have discovered a new massive giant planet, HD 164604 c, which takes about 15 years to orbit its parent star. By combining data from ground-based telescopes and space missions like Gaia, researchers also refined our understanding of a previously known inner planet in the same system.
The study reveals a fascinating orbital dance: the two planets might be moving in opposite directions (a retrograde orbit), suggesting a violent past...
Read article 10. 2. 2026Stars | Exoplanets | White dwarfs | James Webb Space TelescopeUsing the James Webb Space Telescope (JWST), astronomers have conducted a detailed analysis of WD0806 b, one of the coldest planets ever photographed outside our Solar System. Orbiting a white dwarf at a massive distance—about 60 times further than Pluto is from our Sun—this gas giant has temperatures of only 350 K (roughly 77°C). The study identified a cocktail of chemicals in its atmosphere, including water, methane, and carbon dioxide.
