Light patterns suggest the blue supergiant HD 74371 is growing hotter after a past red-supergiant phase. Elsewhere, planets show striking atmospheric weather and escaping helium, while infrared observations reveal a star’s vibrations and a young system’s magnetic activity.

Image: Modeling shows Gliese 486 b
Gliese 486 b is a planet orbiting close to a red dwarf star, where intense radiation likely caused much of its original atmosphere to escape. Scientists used computer models to study how the planet's current water content could be explained by different combinations of an early hydrogen-rich atmosphere and water inventory. They found that even a small amount of hydrogen in the early atmosphere could have protected water from escaping, reducing the amount of water needed to match today's observat...

Image: Hydrogen sulfide detected in the inner disk of HD 163296 reveals sulfur ice sublimation
HD 163296 is a young star surrounded by a disk of gas and dust where planets are forming. Using the ALMA telescope, scientists detected compact emission of hydrogen sulfide (H2S) and sulfur oxides in the innermost part of the disk. The emission comes from a region just 3–5 astronomical units from the star, where temperatures are high enough for sulfur-bearing ices to turn into gas. The observations show that H2S is a major sulfur-containing mo...

Image: Two candidate planets found around Sun-like star HD 161098 in the sub-meter-per-second era
HD 161098 is a Sun-like star located about 30 parsecs away. Using advanced instruments and long-term radial velocity monitoring, scientists have detected two signals that may indicate the presence of planets. The first candidate, HD 161098 b, has a minimum mass of about 3.6 times that of Earth and orbits the star every 72.6 days. The second, HD 161098 c, is more massive, with a minimum mass of about 7.8 Earth masses and an orbital period of 682.5...

HD 25295 b confirmed as a hot sub-Neptune and prime target for future atmospheric studies

Image: HD 25295 b confirmed as a hot sub-Neptune and prime target for future atmospheric studies
HD 25295 b, also known as TOI-4602 b, is a sub-Neptune planet orbiting a bright and quiet star. Precise measurements of its mass and radius show that it is about 2.5 times the size of Earth and 5.5 times as massive. This places it just above the so-called radius valley, a region where few planets are found, and suggests that it is in transition between a sub-Neptune and a super-Earth. The planet's bulk density indicates that it still has a thi...

TOI-1710 A b orbits in the opposite direction to its star's spin, revealing a rare anti-aligned system

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 comp...

JWST and VLT reveal super-solar metallicity and photochemical signs in WASP-96b's atmosphere

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...
