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.

Researchers using the James Webb Space Telescope have analyzed the atmosphere of the sub-Neptune planet HD 15337 c, which is about 2.5 times the size of Earth. The study revealed a 'featureless' spectrum, meaning the planet's atmosphere is likely very thick, enriched with heavy elements, or covered in high-altitude clouds and haze. Interestingly, the planet arrived for its transit earlier than expected, suggesting the presence of an undiscovered neighboring planet pulling on it with its grav...

Image: James Webb Space Telescope probes the mysterious atmosphere of radius-valley planet TOI-260 b
Using the James Webb Space Telescope, astronomers have examined the atmosphere of TOI-260 b, a planet roughly 1.7 times the size of Earth that sits in the mysterious 'radius valley'—a gap where few planets are found. The observations revealed a mostly flat spectrum, suggesting the planet might have a very heavy atmosphere enriched with elements other than hydrogen and helium, or perhaps hidden by high-altitude clouds. While a small potential s...

Image: Future ELT telescope will reveal the atmospheres of sub-Neptune planets V1298 Tau b and TOI-451 c
This study explores the capabilities of the upcoming Extremely Large Telescope (ELT) and its ANDES instrument in analyzing the atmospheres of young, distant planets similar to Neptune but smaller. By simulating observations of the exoplanets V1298 Tau b and TOI-451 c, researchers demonstrated that we will soon be able to detect water, hydrogen sulfide, and carbon monoxide on these worlds. The research highlights that by carefully comparing dat...

Image: Discovery of circumstellar disks around young brown dwarf candidates like DENIS J0534552-104808
Researchers have successfully identified 23 nearby young objects, mostly brown dwarfs, that are surrounded by circumstellar disks of gas and dust. By analyzing data from several space missions and ground-based telescopes, the study found that these disks—the birthplaces of potential rocky planets—exist even around very low-mass objects. Highlights include the detection of ten entirely new disk-bearing candidates and evidence of long-lived accr...

Eating planets makes the star Gliese 504 appear younger

Image: Eating planets makes the star Gliese 504 appear younger
The Sun-like star GJ 504 presents a cosmic mystery: despite being roughly 2 billion years old, it rotates rapidly and possesses an intense magnetic field typical of a much younger star. This study investigates the theory that GJ 504 'rejuvenated' itself by swallowing a Jupiter-sized planet. By mapping the star's magnetic field and simulating its stellar winds, researchers found that the star's current high-energy state and rotation speed cann...

Image: Magnetospheric accretion in the DF Tauri binary star system
This research investigates how young stars grow by pulling in material from their surrounding environment, specifically within the DF Tauri binary system. By using high-resolution observations, astronomers analyzed the primary star in this pair to see if its companion affects how it 'feeds' on gas and dust. They found that despite being part of a double-star system, the primary star follows a traditional growth model where a strong magnetic f...

Image: Small red stars lack the typical gap between rocky planets and gas giants
A comprehensive search of over 8,000 small, cool stars known as mid-to-late M dwarfs has revealed that these stars are the most common hosts for small planets in our galaxy. Unlike larger stars like our Sun, which typically show a clear 'radius valley'—a gap where planets of a specific size are rarely found—these small stars host a continuous range of planet sizes peaking at about 1.25 times the size of Earth. The study found that rocky 'supe...

Image: Spectroscopic study of five pulsating Mira stars and their chemical signatures
This study examines the atmospheric behavior and chemical composition of five well-known Mira-type variable stars: RY Cep, SU Cam, T Cep, V667 Cas, and OR Cep. These aging stars undergo dramatic pulsations that create powerful shockwaves in their atmospheres, leading to the appearance of specific emission lines in their light spectra. By analyzing these spectroscopic changes, the research explains how the balance between carbon and oxygen det...

Image: Mapping the depths of the Orion star-forming complex with high-precision radio astrometry
Using the Very Long Baseline Array, researchers have conducted a detailed survey of young stellar objects within the Orion complex to map its three-dimensional structure with unprecedented precision. By detecting 216 compact radio sources and tracking the movement of 58 of them over multiple epochs, the study successfully measured their distances and motions. The findings reveal that the Orion complex spans distances from 380 to 440 parsecs, p...

Astronomers have successfully characterized three new 'warm Jupiters'—gas giant planets similar in size to Jupiter but with much longer orbits than the typical 'hot Jupiters' found close to their stars. Using data from the TESS space telescope and the new PLATOSpec instrument, the team identified TIC 147027702 b, which orbits its star every 44 days; TIC 245076932 b, a planet with a notably oval-shaped, eccentric orbit and a 21-day period; and...
