V1298 Tau b showed helium absorption during all four observed transits across four years, but its active host star may affect the signal. The latest findings also point to silicate clouds on TOI-561 b, a warped dust ring around CQ Tau, and a giant planet candidate near Boyajian's star that may be surrounded by vast rings. New atmospheric models reveal why gas compositions can vary across hot giant planets.

Scientists have used X-ray observations to create a detailed map of the Fe K emission in the low-mass X-ray binary system 4U 1822-371. This system consists of a compact object, likely a neutron star, and a companion star orbiting each other every 5.57 hours. The study used data from the XRISM satellite, covering eleven orbits of the system, to track how the X-ray emission changes with the orbital period. By analyzing the Doppler shifts in the Fe K line, the researchers produced the first velo...

Image: Pandora mission will help reveal exoplanet atmospheres with new observations
NASA's Pandora mission is a small satellite project designed to study exoplanets and their host stars by separating the effects of star activity from the signals of exoplanet atmospheres. Pandora will observe both visible and near-infrared light from systems where planets pass in front of their stars, allowing scientists to monitor changes in the star and better understand the atmospheres of the planets. The mission, set to run from 2026 to 20...

Researchers have closely examined HD 188101, a little-studied star with a weak magnetic field, using both spectroscopic and photometric observations. This star has properties typical of main-sequence B9 stars, including its effective temperature and surface gravity. The study focused on measuring the amounts of several elements in the star's atmosphere and how these compare to the Sun. The team found that HD 188101 has higher than solar amount...

Image: A new method measures radial velocities of the Sun-like star 66 G. Centauri
A new approach has been developed to measure the movement of stars by analyzing their light in detail. This method does not rely on a reference template, which can sometimes introduce errors, especially when the data is not perfect. It is designed to work with different types of stars and instruments, making it flexible for various astronomical studies. The method, called TILARA (Template-Independent Line-by-line Algorithm for Radial velocity ...

HD 93083 (Gliese 1137) is a orange star already known to host a Saturn-mass planet, HD 93083 b. In this study, scientists analyzed 13 years of precise spectroscopic data to search for new planets and improve our understanding of the known planet's properties. The team refined the orbital parameters and minimum mass of HD 93083 b, providing a more accurate picture of this Saturn-mass exoplanet. In addition, they discovered a new planetary candi...

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 ye...

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...

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...
