A planet’s helium atmosphere streams ahead of its orbit, while infrared observations reveal the hidden rhythms of its star. New work also shows how neutron-star tilt can reshape X-ray light, traces the past of massive blue supergiants, and maps cloudy and clear zones on the hot Jupiter WASP-43 b.

Image: Simulations show how planets accrete stellar wind from aging stars and may become detectable
As stars like the Sun age and evolve, they lose mass through strong stellar winds, which can affect the planets orbiting them. This study used computer simulations to explore how much material planets can accrete from the wind of a star as it goes through its red giant and asymptotic giant branch phases. The simulations covered planets with masses from half to thirteen times that of Jupiter, at distances of 5, 10, and 20 astronomical units from their star. The results show that planets closer...

Image: TOI-1333 A b: a well-aligned hot Jupiter orbiting an F-type star with a tilted stellar companion
The alignment between a planet’s orbit and its star’s rotation axis can reveal how giant planets migrate and evolve, especially in binary star systems. TOI-1333 A b is a hot Jupiter—a giant planet in a close orbit—around an F-type star that also has a distant stellar companion. By analyzing spectroscopic data taken during a planetary transit, astronomers measured the angle between the planet’s orbit and the star’s spin axis, known as the projecte...

Image: JWST reveals a low-metallicity atmosphere for giant planet TOI-5293 A b around a variable red dwarf
TOI-5293 A b is a giant planet about half the mass of Jupiter, orbiting an early red dwarf star every three days. The planet’s atmosphere was studied using two transits observed by the James Webb Space Telescope (JWST). The host star’s surface changes rapidly, making it challenging to interpret the data. In the first transit, the planet crossed regions of the star with different brightness, which contaminated the spectrum. The second transit allo...

Image: Doppler shadow analysis reveals surface features of HD 189733 during planetary transits
Studying exoplanet atmospheres with transmission spectroscopy can be complicated by features on the star’s surface, which can affect the observed spectra. To better understand these effects, astronomers analyzed the surface of the star HD 189733 by observing two transits of its planet using the ESPRESSO spectrograph. They used a technique called Doppler shadow analysis to probe how the star’s spectral lines change from the center to the edge (lim...

Image: Dust traps create a crescent-shaped planet-forming disk around young star HD 163296
High-resolution images from the ALMA telescope have revealed a variety of shapes in the dust of planet-forming disks, including rings, spirals, and crescents. While most disks show symmetrical rings, some display asymmetric features like blobs or crescents, which may be linked to vortices or the influence of forming planets. This study focuses on the disk around the star HD 163296, where a crescent-shaped arc was observed in the dust using ALMA d...

Image: Precise mass and radius measurements reveal diverse compositions for small exoplanets
A new study has analysed six planetary systems, each with at least one small planet passing in front of its star. By combining new and existing observations from space and ground-based telescopes, researchers have measured the mass and size of these planets with high precision. This allows for a better understanding of what these distant worlds are made of and how they might have formed. The team used data from CHEOPS, K2, TESS, and several gr...

Image: TOLIMAN: a small space telescope to search for planets around Alpha Centauri
The TOLIMAN mission is building and preparing to launch a low-cost space telescope with a unique optical design. Its main goal is to search for rocky, Earth-like planets in temperate orbits around the stars Alpha Centauri A and B, the closest Sun-like stars to Earth. Finding such planets is difficult with current instruments, even though these stars are nearby and bright. TOLIMAN will use a technique called narrow-angle astrometry, which measu...

Image: JWST reveals the spectrum of a giant starspot on the M-dwarf TOI-3884
TOI-3884 b is a rare super-Neptune planet that transits a fully convective M-dwarf star with a persistent giant polar starspot. Because the planet passes over this spot during every transit, astronomers can directly study the spot’s properties using the James Webb Space Telescope (JWST). Seven transits were observed with JWST, covering a wide range of wavelengths from 0.5 to 5.3 micrometers. Each transit showed a recurring signature as the pla...

Image: Brown dwarf theory helps explain silicate clouds in giant exoplanet atmospheres
Silicate clouds are a key feature in the atmospheres of many giant exoplanets, but their formation and composition are still being studied. This research compares the silicate clouds seen in four hot Jupiters observed by JWST with theories developed for brown dwarfs, objects that are between planets and stars in mass and temperature. The study also uses evidence from meteorites to show that giant planets forming in the outer regions of protoplane...

Image: TOI-672 b is confirmed as a hot super-Neptune, shedding light on the Neptunian desert around red dwarfs
The Neptunian desert is a region where Neptune-sized planets are rare at short orbital periods, likely due to intense starlight stripping away their atmospheres or changes in their orbits. Understanding this desert helps scientists learn how planets evolve, especially around different types of stars. In this study, astronomers confirmed the existence of TOI-672 b, a massive super-Neptune orbiting a red dwarf star, using data from TESS, ground-bas...
