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.

Image: TOI-1710 A b orbits in the opposite direction to its star
TOI-1710 A b is a warm Neptune-sized planet that orbits its star in the opposite direction to the star's rotation, a configuration known as anti-alignment. This rare arrangement was discovered using the Rossiter-McLaughlin effect, which measures how the planet's transit affects the star's light. The planet's orbit is almost exactly opposite to the star's spin, with a true obliquity of about 158 degrees. The host star has a distant M-dwarf companion, but this companion is too far away to have ...

Image: JWST and VLT reveal super-solar metallicity and photochemical signs in WASP-96b
WASP-96b is a hot Saturn-like planet whose atmosphere has been studied using both the James Webb Space Telescope and ground-based telescopes. The combined data show clear signs of water vapor, carbon dioxide, and sodium in the planet's atmosphere. While carbon monoxide could not be confirmed, the results suggest that the atmosphere contains two to six times more heavy elements than its star, a property known as super-solar metallicity. The pla...

Image: JWST search for exomoons around TOI 700 d and e sets new limits and refines planet properties
Scientists used the James Webb Space Telescope to search for exomoons, similar to Earth's Moon, around the rocky planets TOI 700 d and e, which orbit in the habitable zone of a red dwarf star. While no exomoons were detected, the study improved the precision of the planets' orbits and sizes, making future searches more effective. The team found a noise signal in the data, likely caused by the star's surface activity, which made it harder to de...

Image: WASP-11 b: transit timing and optical spectrum reveal stable orbit and atmospheric features
WASP-11 b, also known as HAT-P-10 b, is a hot Jupiter with a low density, making it a good candidate for studying its atmosphere. Researchers collected 31 new transit observations and combined them with previous ground-based and space-based data to refine the planet's properties and analyze its orbit over 16 years. The updated analysis shows that WASP-11 b's orbit is stable, with no signs of orbital decay or additional planets affecting its mo...

Image: Aligned orbits found in double M dwarf system and trends across planets, brown dwarfs, and binaries
A new study has measured the alignment between the spin of an M dwarf star and the orbit of its very-low-mass stellar companion, marking the first such measurement for a double M dwarf system. Using the Rossiter-McLaughlin effect, researchers found that the two stars are well aligned, meaning the companion orbits in the same direction as the primary star spins. This suggests the system either formed aligned or was later realigned by tidal forces....

Image: Magnetic field of GJ 436 b revealed by planet-induced changes in its star
GJ 436 is a red dwarf star with a Neptune-sized planet, GJ 436 b, orbiting close by. Scientists have long suspected that magnetic interactions between such planets and their stars could produce detectable signals, but direct evidence has been rare. In this study, researchers analyzed 17 years of spectroscopic data and found repeated increases in the star's activity that match the planet's orbital period and the star's rotation. The team develo...

Image: JWST reveals low-metallicity atmosphere and stellar effects for giant planet HATS-75 b
HATS-75 b is a giant planet orbiting a red dwarf star, recently studied as part of a program using the James Webb Space Telescope. Scientists observed three transits of the planet, where it passed in front of its star, to analyze its atmosphere. The planet's spectrum showed a deeper transit at shorter wavelengths, which can be caused by hazes in the atmosphere or by features on the star's surface, such as starspots and bright regions. By compa...

Image: Turbulence measured in the outer disk of HL Tauri reveals strong nonthermal motions
HL Tauri is a young star surrounded by a protoplanetary disk with rings and gaps, where planets may be forming. Understanding turbulence in such disks is important because it affects how material moves and how planets grow. Until now, the strength of turbulence in the outer parts of these disks was not well known, especially in systems still gathering gas from their surroundings. Researchers used ALMA telescope data to study the disk around HL...

Image: JWST eclipse observations probe atmosphere and surface of rocky planet Gliese 3473 b
Gliese 3473 b (GJ 3473 b) is a rocky exoplanet orbiting close to its star, making it highly exposed to intense starlight. Scientists used the James Webb Space Telescope to observe the planet as it passed behind its star, a phenomenon called a secondary eclipse. These observations help reveal whether the planet has an atmosphere or if it is a bare rock, a key question for understanding how such worlds evolve under strong stellar radiation. The ...

DO Tau is a young star surrounded by a disk of gas and dust, where planets may eventually form. This system is a T Tauri star, a type of young, Sun-like star still gathering material from its surroundings. By combining high-resolution infrared spectra and advanced imaging, researchers have studied the region where the star and its disk interact, revealing new details about how material moves from the disk onto the star. The team used two main ...
