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: TOI-4504’s giant planets locked in deep resonance, echoing Gliese 876’s dynamics
TOI-4504 is an orange dwarf star that hosts two giant planets, both orbiting in a special pattern called a 2:1 mean-motion resonance. This means that for every orbit the outer planet completes, the inner planet completes exactly two. The planets, named TOI-4504 c and d, have orbital periods of 82.8 and 41.3 days, respectively, and show some of the largest known variations in the timing of their transits across the star. Recent data from the TESS mission revealed that the inner planet, previou...

Image: TESS reveals how planet size shapes orbital eccentricity for warm single exoplanets
Astronomers have used data from NASA’s TESS mission to study 347 single exoplanets with orbital periods between 8 and 200 days. These planets, called 'warm' because they are neither too close nor too far from their stars, show a surprising link between their size and the shape of their orbits. The team analyzed the planets by grouping them into size categories: sub-Neptunes, sub-Saturns, and Jovians. They found that most small and medium-sized...

Image: DMPP survey finds new planets and high occurrence rates around active stars
The Dispersed Matter Planet Project (DMPP) is a survey using the radial velocity method to search for planets around stars that show unusual activity, which may be caused by close-in planets losing their atmospheres. This project aims to understand how common such planets are and to find new examples. In this study, researchers discovered seven new planetary signals in five different star systems, including DMPP-2c and d, HD67200/DMPP-6b and c...

Image: Circular orbits are common in binary star systems with periods shorter than three days
An eclipsing binary star system consists of two stars orbiting each other so close that they periodically block each other's light as seen from Earth. Over millions to billions of years, gravity between these stars reshapes their orbits and spinning rates in a process called tidal evolution, which helps us understand how both close star pairs and exoplanet systems change over time. Researchers examined 68 binary pairs (among them EBLM J0040+01...

Image: Nova eruption of RS Ophiuchi in 2021 generated million-degree gas and transformed the companion red giant
RS Ophiuchi is a recurrent nova system, where a white dwarf and a red giant star orbit each other closely. The dwarf sucks material from the giant which leads to repeating eruptions known as nova. In 2021, RS Ophiuchi experienced another eruption, providing astronomers with a rare chance to observe changes before, during, and after the event using near-infrared light. Researchers collected spectra before the eruption, showing the signature of ...

Image: X-ray source in 4U 1822-371 found where the stream of matter from secondary star hits the neutron star
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 ...

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...
