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: Three massive planets discovered orbiting distant low luminosity red giant stars
Researchers have identified three massive planets orbiting two low luminosity red giant stars, marking a significant addition to our understanding of planetary systems around evolved stars. These stars, which have expanded and cooled after exhausting the hydrogen fuel in their cores, are a unique environment for planet formation and survival. The study, part of a long-term campaign using the CORALIE spectrograph, focused on observing changes in the light spectrum of stars to detect the gravitati...

Image: Two young giant planets discovered with the longest orbital periods for their class
Astronomers have identified two young, large-radius planets orbiting the F-type star HD 114082, marking them as the longest-period young transiting exoplanets currently known. These planets, designated b and c, were detected through a collaborative effort using data from multiple space and ground-based telescopes, including TESS, the Next-Generation Transit Survey (NGTS), the Characterising Exoplanet Satellite (CHEOPS), and the Antarctic Search f...

Image: Three newly discovered hot Jupiters provide insights into late-stage planetary evolution
Understanding how giant planets evolve is essential for building a complete picture of planetary systems. While many exoplanets have been found, studying their changes over time requires observing systems in different stages of development. A recent discovery has added three new gas giant planets — known as hot Jupiters — orbiting stars that are approaching the end of their main sequence, a critical but less studied phase of planetary life. Th...

Image: UV radiation from host stars complicates search for life on TRAPPIST-1 e
The search for life on distant planets often relies on identifying biosignatures — gases like oxygen or methane that are produced by biological processes. However, a new study highlights how the specific ultraviolet (UV) radiation from a host star can significantly influence a planet's atmospheric chemistry, potentially creating false-positive signals that might be mistaken for life. The research focused on the planet TRAPPIST-1 e, which orbits a...

Image: Chemical differences in binary star pair suggest planetary engulfment
Stars born from the same cloud in a binary system are generally expected to have identical chemical compositions. However, some binary systems exhibit unexplained chemical differences, leading researchers to debate whether these anomalies originate from their birth environment or are the result of external events. This study examines the binary pair HD 129171 and HD 129209, which show significant differences in their abundances of iron, lithium, ...

Image: Planetary engulfment may explain the chemical paradox in the binary system HD 81809
The binary star system HD 81809 presents a significant chemical mystery, as its two components exhibit a striking difference in metallicity — the abundance of elements heavier than hydrogen and helium. While the primary star has a low metallicity, the secondary star, HD 81809B, shows a metallicity closer to that of our Sun. Scientists are investigating whether this anomaly could be the result of the secondary star having engulfed one or more plan...

Image: JWST observations confirm magnesium silicate clouds in the atmosphere of HD 209458b
HD 209458b is perhaps the most famous hot Jupiter, having been the first planet where researchers successfully measured atmospheric composition and discovered hints of aerosol-related effects. These massive, hot gas giants provide essential insights into planetary atmospheres, but confirming the specific composition of their clouds has remained a challenge. New observations from the James Webb Space Telescope (JWST) have now directly measured the...

Image: Updated modelling framework reveals the orbital alignment of the hot Jupiter TOI-135 b
Understanding the orientation of an exoplanet's orbit relative to its host star's rotation provides essential clues about the system's past. A key method for measuring this alignment is the Rossiter-McLaughlin effect, which occurs when a transiting planet blocks different parts of a rotating star, creating a characteristic shift in the star's spectral lines. Researchers have now introduced an improved modelling framework within the exoplanet anal...

Image: Pan-Pacific survey clarifies the nature of six candidate companions orbiting evolved stars
The Pan-Pacific Planet Search was a six-year survey that monitored 164 southern evolved stars to detect potential orbiting companions using radial-velocity measurements, which track the slight wobble of a star caused by the gravitational pull of orbiting objects. In their final data release, researchers aimed to resolve the true nature of six speculative candidates that had been identified during the survey. By combining new radial-velocity da...

Image: High-resolution spectroscopy reveals gaseous silicon in the atmosphere of brown dwarf TWA 5 B
TWA 5 B is a directly imaged sub-stellar companion, a type of object often categorized as a gas giant or brown dwarf. Understanding the chemical composition of these atmospheres is essential for learning how they formed. Silicon is a particularly important element, as it is a refractory material — a substance that remains solid at relatively high temperatures — and it plays a major role in the formation of magnesium-silicate clouds, which are sim...
