Image: Orbital analysis of Kepler-451 reveals evidence for a circumbinary planet
Kepler-451 is a binary star system hosting a planet that orbits both stars, known as a circumbinary planet. By analyzing the timing of eclipses between the two stars from 2004 to 2024, the study investigated variations in the orbital period. These variations, which appear as shifts in the expected timing of eclipses, provide clues about gravitational influences from additional objects in the system or internal changes within the stars themselves. The analysis focused on building models to exp...

Image: Stellar passage of HD 7977 likely triggered a comet shower in our solar system
Long-period comets, which take thousands of years to orbit the Sun, are traditionally thought to be nudged toward the inner solar system by the gravitational pull of the Milky Way's disk. New evidence suggests that the star HD 7977 may have passed close to our solar system 2.5 million years ago, creating a "comet shower" that continues to influence the number of comets we observe today. The research compared computer simulations of long-period...

Image: Glossy silicate clouds discovered on the dayside of ultra-hot planet LTT 9779 b
LTT 9779 b is an ultra-hot Neptune-sized planet orbiting in a region of space known as the Neptunian desert, where such worlds are typically not found. Recent observations have provided the first clear evidence of clouds on the dayside of this planet. These clouds, made of silicate—a common mineral found in rocks—act as a highly reflective layer, explaining why the planet appears so bright when viewed from space. The analysis confirms that the...

Image: New model measures global atmospheric wind speeds on the planet WASP-76 b
Atmospheric 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 thi...

Image: Circumstellar disks observed around five massive Herbig Be stars
Herbig 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...

Image: Transit of giant exoplanet HIP 41378 f shows significant timing variations
The giant exoplanet HIP 41378 f, which orbits its host star every 542 days, has been observed during a 19-hour transit event. 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. ...

Image: Atmosphere of giant planet TOI-6894 b reveals ammonia and chemical signatures
TOI-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...

Image: Third giant exoplanet discovered orbiting the star Beta Pictoris
A third giant exoplanet has been discovered in the Beta Pictoris system through direct imaging, marking a significant milestone in planetary science. 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 ...

Image: Formation history of sub-Neptunes TOI-421 b and Gliese 3470 b reveals water-poor environments
Sub-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...

Image: Interior structures of cold super-puff planets studied for consistency with accretion theory
Super-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...
