A giant planet candidate near Boyajian’s star may look oversized because a broad ring system surrounds it, not because the planet itself is unusually large. New atmospheric models also show why methane and carbon monoxide can vary across hot gas giants, exposing major limits in simpler predictions.

Image: Observations reveal evidence of a potential stellar companion for the red supergiant Betelgeuse
Betelgeuse, one of the most prominent red supergiant stars in the night sky, has long been a subject of intense scientific inquiry. Recent analysis has sought to verify the existence of a secondary star orbiting this massive primary. By examining the star’s long secondary period of variability, which suggested the presence of an orbiting body, researchers targeted the system to confirm if a companion star was indeed present in the vicinity of this stellar giant. Using extreme adaptive optics,...

Image: Planet engulfment remains a possible cause for lithium enhancement in TOI-5882
TOI-5882 is a subgiant star—a star in the later stages of its life—that is notably rich in lithium. This star hosts a massive brown dwarf, an object larger than a giant planet but smaller than a star, orbiting every 7.1 days. The high levels of lithium found in the star have led to the hypothesis that the star may have recently consumed a smaller planet, such as a super-Earth or a Neptune-sized world, whose material would alter the star's chemica...

Image: Helium-dominated atmospheres on rocky planets provide unique climate conditions for potential life
Climate models of rocky planets with helium-dominated atmospheres suggest these worlds may possess distinct thermal characteristics compared to planets with more common gases like nitrogen or hydrogen. Because helium is a simple atom with fewer internal ways to store energy, it creates a specific temperature profile that influences how heat is distributed and retained on a planet's surface. The study compared the warming effects of helium to n...

Image: Magnetic field and potential planet candidates of the nearby Red dwarf Gliese 729
Gliese 729 (Ross 154) is the seventh closest Red dwarf to the Sun and serves as a significant subject for exoplanet research. Because Red dwarfs are typically very active, their magnetic fields can create noise that masks the subtle signals of orbiting planets. By analyzing a decade of data, the magnetic field of Gliese 729 has been mapped, revealing how its activity affects the search for small, rocky worlds in its vicinity. The research util...

Image: Horizontal quenching explains missing methane in the atmosphere of planet WASP-43 b
WASP-43 b is a hot Jupiter—a gas giant planet orbiting extremely close to its parent star. By using sophisticated three-dimensional computer simulations to analyze data from the James Webb Space Telescope, researchers have modeled the complex chemistry of the planet's atmosphere. The study focused on understanding how atmospheric circulation and chemical reactions influence the distribution of gases across the planet's day and night sides. The...

Image: Radio signal from HD 189733 system observed using NenuFAR telescope
Researchers have identified potential radio signals coming from the HD 189733 system, a discovery that may offer insights into the magnetic fields of planets outside our solar system. Detecting such auroral radio emissions—light produced when charged particles interact with magnetic fields—is a key method for understanding the interiors and potential habitability of distant worlds. The signal was recorded at low frequencies. The team analyzed ...

Image: Orbital companion dynamics influence the dust disk structure around CQ Tauri
The star CQ Tauri shows indirect signs of a companion affecting its surrounding environment. Observations reveal a large cavity in the disk of material around the star, measuring approximately 25 astronomical units across, with a prominent ring of dust peaking at a distance of 53 astronomical units. An astronomical unit is the average distance from the Earth to the Sun. To understand this structure, researchers simulated how gas and dust behav...

Image: Two low-density planets confirmed orbiting the bright star HD 148797
The bright F-type star HD 148797 hosts two moderate-period planets, classified as sub-Jovian worlds with unusually low density. These planets reside in a region of space known as the Neptunian savanna, a classification for planets with specific ranges of size and orbital distance. The findings provide insights into how such systems form and evolve, suggesting they often develop in dynamically stable environments rather than through violent orbita...

Image: Wide-orbit stellar companions influence formation of giant planets around Red dwarf stars
The giant planet TOI-5628Ab orbits a mid-type Red dwarf star every 4.34 days. This planet is part of a complex system that also includes a distant white dwarf companion, a remnant of a star that has exhausted its nuclear fuel. By studying this system and comparing it to a wider population of similar stars, the research identifies a strong connection between the presence of distant stellar companions and the existence of large planets orbiting ver...

Image: Orbital analysis of π Mensae system updates parameters for three potential exoplanets
The π Mensae star system, which hosts the first exoplanet detected by the Transiting Exoplanet Survey Satellite (TESS), has been the subject of a comprehensive new study. By combining six years of TESS photometry — the measurement of a star's brightness over time to detect dips caused by orbiting planets — with 22 years of radial velocity data, which tracks the tiny wobbles in a star’s motion caused by a planet’s gravitational pull, this research...
