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.

M dwarf stars are small, cool stars that are popular targets for finding exoplanets because their size makes it easier to detect planets in their habitable zones. However, these stars often have magnetic activity that can mimic the signals of planets, making it important to understand their activity cycles. This study focused on two M dwarfs, Gliese 617 A and Lalande 21185 (Gliese 411), both known to host exoplanets. Researchers analyzed 13 years of high-resolution spectra from the SOPHIE spe...

Image: Vertical structure of the Beta Pictoris debris disk revealed across multiple wavelengths
β Pictoris is a well-known star surrounded by a disk of dust and debris, making it a prime example for studying how planetary systems evolve. By observing this disk at different wavelengths, scientists can learn about the structure and behavior of the material around the star. This study focused on measuring the vertical height of the disk using images from mid-infrared to millimeter wavelengths. Researchers used advanced modeling to analyze t...

Image: Methanol search in the water-rich planet-forming disk around HL Tauri
HL Tauri is a young star surrounded by a disk of gas and dust where planets are forming. Scientists are interested in finding complex molecules like methanol in such disks because these molecules are important for the chemistry that could lead to life. Methanol is often found around other young stars, but its presence in planet-forming disks is rare. In this study, researchers looked for methanol in the disk around HL Tauri, motivated by the d...

Image: Volcanic activity and mantle dynamics shape the lava world K2-141 b
K2-141 b is an ultra-short period planet, known as a lava world, that orbits very close to its star. This extreme environment causes one side of the planet to be extremely hot, covered by a magma ocean, while the other side remains much cooler and solid. Scientists used computer models to study how the planet's interior moves and how this affects volcanic activity, especially on the nightside, which is not directly heated by the star. The rese...

Image: The four planets in the TOI 2076 system reveal early atmospheric loss and fragile orbits
TOI-2076 is a young star system, about 200 million years old, that hosts four planets slightly larger than Earth. These planets, called sub-Neptunes, orbit close to their star and offer a unique look at how planetary systems change in their early stages. Unlike many young systems where planets are locked in precise orbital patterns called resonances, the planets in TOI-2076 are near but not exactly in resonance, making their arrangement less stab...

Image: JWST reveals planetary dynamics and possible hidden companion in TWA 7 system
TWA 7 is a young star surrounded by a debris disk, which is a ring of dust and small objects left over from planet formation. Recent observations with the JWST telescope have directly imaged a planet far from the star and revealed detailed features in the disk, such as a sharply defined inner edge and an unusual horseshoe-shaped structure. These features suggest that the system's planets are shaping the disk in complex ways. Researchers used c...

Image: TOI-1080 b: a small rocky planet around a quiet M4V star is validated for detailed study
Researchers have detected and validated TOI-1080 b (SIPS J1825-5212 b), a small, temperate exoplanet that transits its quiet M4V host star every 3.97 days. The host star is located 25.6 parsecs away. The planet was first identified by the TESS mission and confirmed with both TESS and ground-based observations. Analysis of the light curves shows that TOI-1080 b has a radius of about 1.2 times that of Earth and an equilibrium temperature of 36...

Scientists have used high-resolution transmission spectroscopy from the Gemini-South telescope to study the atmosphere of the temperate super-Earth exoplanet L 98-59 d. This approach, typically used for larger and hotter planets, was successfully applied to a smaller, more temperate world, demonstrating the capability of ground-based facilities to characterize super-Earth atmospheres. The team confirmed the presence of hydrogen sulfide (H2S) i...

Image: TESS survey shows the radius valley vanishes for planets around mid-to-late M dwarfs
Researchers conducted the most comprehensive search for planets around mid-to-late M dwarf stars using data from the TESS mission. Surveying over 8,000 such stars, they identified 77 transiting planet candidates and measured how often planets occur as a function of their size, orbital period, and the amount of starlight they receive. The study found that each mid-to-late M dwarf hosts on average about 1.1 planets larger than Earth within 30 ...

Image: JWST reveals clues to the atmosphere of Jupiter-analog exoplanet epsilon Eridani b
Scientists conducted the most sensitive direct imaging search for the nearby Jupiter-analog exoplanet epsilon Eridani b using the JWST/NIRCam coronagraph between 4 and 5 micrometers. Despite achieving a record-breaking contrast sensitivity at the planet’s expected separation, the planet itself was not directly imaged. The study updated the age of the host star epsilon Eridani to 1.1 billion years, which affects the estimated temperature of t...
