A giant planet candidate near Boyajian’s star may look oversized because a broad ring system surrounds it, not because the planet itself is unusually large. New atmospheric models also show why methane and carbon monoxide can vary across hot gas giants, exposing major limits in simpler predictions.

Image: Two warm saturn-mass planets found orbiting the star TOI-3850
A multi-planet system has been identified orbiting TOI-3850, a G0 dwarf star similar in metallicity to our Sun. The system contains two warm planets—gas-rich worlds that orbit closer to their star than Jupiter, but further than the extremely hot planets commonly found in close proximity to their hosts. These planets are currently situated near a gravitational configuration known as a 2:1 mean motion resonance, where the outer planet completes one orbit for every two orbits of the inner planet. ...

Image: Radial velocity analysis characterizes planetary systems around DMPP-7 HD 67200 and HD 2134
Recent observations have analyzed the environments around three stars - DMPP-7, HD 67200, and HD 2134 — to search for evidence of orbiting planets. By studying radial velocity, which measures the tiny wobbles in a star’s position caused by the gravitational tug of an orbiting planet, the project examined these systems to distinguish between genuine planetary signals and the natural activity of the stars themselves. The researchers used a Bayes...

Image: Analysis of dust rings in the protoplanetary disk around LkCa 15
Protoplanetary disks are vast, swirling clouds of gas and dust surrounding young stars that eventually coalesce to form planets. A new method has been developed to analyze the physical properties of these disks by examining how their dust rings appear when viewed at an angle. By studying these shapes, researchers can determine the intrinsic width, thickness, and light-blocking capacity, known as optical depth, of the dust material within the disk...

Image: Lambda Bootis phenomenon identified in the massive early B-type star HD 37356
The Lambda Bootis phenomenon is a unique chemical condition in stars where certain elements, known as refractory elements (materials that condense at high temperatures, such as iron), are significantly less abundant than expected, while volatile elements remain at normal levels. This feature has now been identified in the massive early B-type star HD 37356, marking the first time this characteristic has been observed in such a massive stellar obj...

Evaporating planet explains gaseous disk formation around white dwarf WD J0914+1914

Image: Evaporating planet explains gaseous disk formation around white dwarf WD J0914+1914
The white dwarf WD J0914+1914 is surrounded by a ring of gas containing hydrogen, oxygen, and sulfur. This material originates from a nearby Neptune-like or super-puff planet—a planet with a very low density—that is losing its atmosphere due to intense radiation from the star. The escaping gas forms a disk around the star, which is then slowly pulled onto the white dwarf's surface, creating the unique light signals observed by instruments. Adv...

Image: Climate simulations of exoplanet Ross 128 b suggest low reflectivity for rocky worlds
The exoplanet Ross 128 b, which orbits a nearby Red dwarf star, serves as a primary model for understanding the atmospheres of rocky worlds. By simulating various climate conditions and atmospheric compositions, new research assesses how these planets reflect light, a critical factor for future observations using high-contrast imaging and high-resolution spectroscopy—techniques that separate a planet's light from its host star to analyze its atmo...

Image: Atmospheric analysis of giant planet TOI-3235 b reveals challenges with red dwarf stars
The giant planet TOI-3235 b, which has a mass about two-thirds that of Jupiter and a temperature of 604 Kelvin, orbits a small Red dwarf star. Studying the atmospheres of such massive planets around small, cool stars is important for understanding how they formed, as current theories suggest they should be rare. However, light from the host star often interferes with these observations, creating signals that can be mistaken for atmospheric featur...

Image: Candidate hot Jupiter planet observed orbiting the star TOI-3272
The star TOI-3272 is currently under investigation for hosting a potential hot Jupiter, a massive gas giant planet that orbits extremely close to its host star. Researchers identified this candidate using data from the Transiting Exoplanet Survey Satellite (TESS), which detects the periodic dimming of stars caused by a planet passing in front of them. The system is particularly interesting because the host star appears to be relatively young, wit...

Image: Stellar activity impacts detection of carbon dioxide on planet TRAPPIST-1f
The TRAPPIST-1 system contains seven Earth-sized planets orbiting a red dwarf star. Studying their atmospheres using transmission spectroscopy—a method where starlight passes through a planet's atmosphere during a transit—is complicated by the star itself. Active regions on the stellar surface, such as starspots, can mimic or mask the signals of atmospheric gases, making it difficult to distinguish between the planet's actual composition and the ...

The sub-Neptune exoplanet HD 191939 b, a world larger than Earth but smaller than Neptune, has been examined to understand its atmospheric composition. Observations were conducted to analyze how light filters through the planet's atmosphere, a method known as transmission spectroscopy, which helps identify the gases present. The results show a flat spectrum with no distinct signatures, suggesting the presence of clouds or hazes that hide the deep...
