Estrellas | Exoplanetas | Júpiter calienteAtmospheric circulation on ultra-hot Jupiters—massive gas planets that orbit very close to their host stars—can be studied by observing how light emitted by the planet shifts in frequency. A new computational method has been developed to translate these subtle light shifts into precise measurements of wind speeds across the planet’s surface. This approach provides a clearer picture of how gases move on extreme worlds like WASP-76b.
To test this model, the team applied it to synthetic thermal ...

24. 6. 2026Estrellas | Estrellas masivas de la secuencia principal | Formación planetariHerbig Be stars are young, massive stars that are still in the early stages of their development. Understanding whether these stars host disks of dust and gas is essential to determine if they can form giant planets. A recent survey of 24 of these massive young stellar objects, located within 3,000 light-years of Earth, has provided new insights into the existence and nature of these planet-forming environments.
The research identified 1.3-mil...

This rare long-period planet, roughly 9.5 times the radius of Earth, provides researchers with a look into planetary systems that are difficult to study. By capturing this transit, the timing of the planet's passage was measured, confirming significant deviations from expected patterns known as transit timing variations.

Read article 24. 6. 2026Estrellas | ExoplaneTOI-6894 b is a temperate gas giant planet orbiting a red dwarf star. With a temperature of 420 Kelvin, this sub-Saturn sized world is a unique object of study as the only known giant planet transiting a very low-mass red dwarf star. Recent observations have provided a clear look at its chemical composition, showing that its atmospheric structure and metal content closely mirror those of the gas giants within our own solar system.
The planet's...

This new world, designated Beta Pictoris d, joins two previously known planets orbiting this young, nearby star. The discovery was made by combining modern ground-based observations with archival data, revealing a planet that orbits at a greater distance than its siblings while remaining aligned in ...
Read article 22. 6. 2026Estrellas | Exoplanetas | Atmósferas planetarias | TESSSub-Neptunes—planets larger than Earth but smaller than Neptune—exhibit a wide variety of atmospheric compositions. These characteristics are dictated by the raw materials available during a planet's formation, such as rock, water, and refractory carbon, commonly referred to as soot. By modeling how these materials assemble to form planetary interiors and atmospheres, researchers have clarified the chemical history of several known exoplanetary s...
Read article 21. 6. 2026Super-puffs are a class of exoplanets characterized by sub-Saturn masses and extremely low bulk densities. Because these planets have such a low density, they are often compared to cotton candy due to their puffy appearance. While some of these planets can be explained by standard core accretion theory—the process where planets form through the gradual accumulation of dust and gas in a protoplanetary disk—others present a significant challenge to...
Read article 21. 6. 2026Estrellas | 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 r...
Read article 21. 6. 2026EstreDeuterium 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. 2026Estrellas | 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...
