A star’s hidden vibrations, a planet’s escaping helium, and worlds wrapped in shifting clouds reveal how much can be learned from changing light. Recent observations trace WASP 121’s surface motions in infrared for the first time, map the uneven clouds of WASP-43 b, and catch helium streaming ahead of TOI-3884 b. Light patterns also place the massive star HD 74371 on a return journey toward bluer colors after its red supergiant phase, while search interest spans Proxima Centauri b, Alpha Centauri, and many other stellar neighbors.

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. Transit timing variations occur when the gravita...

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...

Image: Orbital motion of spiral structures around HD 135344B indicates a hidden protoplanet
The 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...

Deuterium limits measured in spectra of HD 32115 and 21 Peg

Image: Deuterium limits measured in spectra of HD 32115 and 21 Peg
Deuterium 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...

Image: Three dimensional simulation of photochemical haze formation in the atmosphere of HD 189733b
Photochemical 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...

Image: Geochemical evolution of Gliese 1132 b influenced by internal mantle redox states
The internal state and atmospheric composition of rocky planets are heavily dictated by the exchange of gases between a molten mantle and the air above it. For planets orbiting very close to their stars, this process can continue for billions of years. A new analysis of the super-Earth Gliese 1132 b examines how the oxidation state of a planet's interior—specifically how oxygen availability affects the melting point of rocks—changes how these wor...

Image: HD 48914 binary system characteristics measured via photometric and radial velocity data
HD 48914, also known as V505 Mon, is an eclipsing binary star system consisting of a Be-shell star—a star surrounded by a shell of gas—and a companion star that has lost much of its outer material. This system demonstrates high-speed rotation and complex interactions between the two stars. By combining new observations from the TESS space mission with existing photometric data—measurements of light brightness over time—and radial velocity data, t...
